The free and open-source project behind Google Chrome


Here, you see your Chromium version.
Works only if your browser is based on Chromium like Google Chrome, Chromium browser, Opera, Vivaldi...

Windows 10, 8, 7

Chromium is not available on XP and Vista since version 50. For help, version 49 (stable and portable) works fine.

Chromium on iOS is a big fake!

Check the official build instructions to understand that Chromium cannot use the existing content/implementation, which is based on V8/Blink and is multiprocess. Go your way! ^^


Obviously, you know this site is not the Chromium official website. As a regular user (not an expert), I created it because I did not find a simple way to download good releases. I try to keep it as safe and fast as possible! ;) This is absolutely a non-profit site. Please, read the #privacy-policy (on the right-hand side).

In short:
  • The official website is development oriented. Users are invited to download Google Chrome.
  • The official download page gives to users only "Nightly" builds (using the official Snapshots repository).
  • This site gives to users a choice of builds: "Nightly" (also on its simplest download page), LKGR, stable and portable builds.

All downloads are from reliable sources only:
  • Google Storage → official "Nightly" builds (Check Chromium Buildbot ^^)
  • SourceForge → most of other free and open-source builds
  • well-known file hosting sites → few other free and open-source builds


1. Project

Chromium exists since 2008. It is the free and open-source project (#features) behind the famous Google Chrome browser. Intrinsically, Chromium is a Google project maintained by many authors (developers, engineers, graphic designers, security researchers...) from Google, Opera, Yandex, Samsung, Intel, Nvidia, Adobe, Hewlett-Packard, BlackBerry... So Chromium is not made by Google!

2. Stable Chromium version

Officially, Chromium does not have a stable release. The official developers do not release it to end users. So it is continually in development. Google Chrome is the stable release... but is not open-source.

In fact, Chromium has a stable version. ^^
Example: The current stable version on #linux is 55.0.2883.75. In this version, there are 75 patches which correct many issues (bugs, feature requests, enhancements...). Because Chromium is open-source (#source-code), anybody can build it. You must be a developer to do this. Just get the current stable version (55.0.2883.75) from the official Git repository and compile it!

The stable version is used in:

3. Development

Basically, Chromium has few versions every day, but you can stick with a version for about a month before you need to upgrade.

Snapshots builds are compiles of the Chromium code whenever there are submitted code changes. A snapshot build will be created as long as the code compiles successfully and its binary files will be stored in the Snapshots repository of Google Storage. Each snapshot build is then run through the automated tests. If that snapshot build successfully passes the automated tests, it is considered as LKGR build.

Note LKGR builds were stored in the Continuous repository until Friday, 18 Mar 2016 (8 months ago). The Chromium team has removed few LKGR builders (407399, 576253 and chromium-dev) but LKGR testers still work (Status dashboard for LKGR, List of the last 100 potential LKGRs, Latest LKGR commit, Latest LKGR builds). Finally, there is no LKGR binary shared by the Chromium team... but any developer can re-compile it! ^^

In resume:
  • Snapshots: Untested and may be unstable versions (known as "Nightly" builds). Official download page
  • LKGR: Tested and more stable versions. Also used by Google Chrome channels: Canary, Dev, Beta and Stable.

4. Finally

Except for stable and LKGR versions, this site uses the official Snapshots repository.

So I give you the opportunity to download only nice Chromium releases ;)
If you want, check the simplest multilingual page: → download/

This entire website (#news and #api included) is auto-updated each hour by the server itself.

Thanks for your attention.
Have a good time! ;)


Chromium vs Google Chrome.

Chromium browser has:
  • only open-source licenses (BSD license, MIT license, LGPL, MS-PL and MPL/GPL/LGPL tri-licensed code) plus unlicensed files. It is a FOSS project. A full list of software developed by third parties is available within the browser at chrome://credits
  • a blue-colored logo
  • the similar sandboxed processes as Google Chrome
  • the similar UI and settings as Google Chrome
  • the built-in Chrome PDF Viewer, on Windows OS (known as PDFium)
  • the built-in Chromoting Viewer (To use it, you need to first install the Chrome Remote Desktop app)
  • the built-in Google Native Client
  • the built-in Print preview and print system
  • no stable version offered by the official team (aka The Chromium Authors)
  • no digital signature
  • no auto-update system (Solutions: Use an #updater • Use PPA on #linux)
  • no built-in Flash player (Solution: Check the #flash part)
  • no support of proprietary codecs (AAC, MP3, H.264) (Solution: Check the #html5-audio-video part)
  • no user RLZ identifier
  • no user metrics (usage statistics) (opt-in option)
  • no crash report (opt-in option)
  • More details on the official site, focused on Linux.

Some developers maintain forks of Chromium that offer more features and enhancements. Thanks a lot for developers! ;)

And if you want to follow new Chromium features, check the Google+ posts of the Chromium Evangelist at Google


There is 1 type of Flash plugin for Chromium:
  • The PPAPI plugin: PepperFlash
  • The NPAPI plugin: Flash Player (#npapi)

PepperFlash is more secure because it works in sandboxed processes.

On Windows, Chomium find PPAPI Flash (.dll file) without command-line flags.
I tested on Win7 (64-bit) and WinXP (32-bit) with Chromium (32/64-bit) + Adobe's Flash installers → It works!

Now the tutorial is simpler:
  1. Install PepperFlash (PPAPI) from Adobe
  2. Check chrome://plugins
  3. Enjoy!

Jerry • Saturday, 7 Mar 2015

Now, the full manual installation tutorial...
(If Google Chrome is already installed, go directly to the step 3)

1. Get PepperFlash (PPAPI)

This plugin is a non-free (proprietary) software developed by Adobe, and distributed bundled with Google Chrome. So get it from the official sources: Adobe or Google.

1.1 From Adobe

Different official ways:
After install, the plugin path will be:
- On a 64-bit #windows:
  • C:\Windows\system32\Macromed\Flash\pepflashplayer64_[version].dll (64-bit version)
  • C:\Windows\SysWOW64\Macromed\Flash\pepflashplayer32_[version].dll (32-bit version)
- On a 32-bit #windows:
  • C:\Windows\system32\Macromed\Flash\pepflashplayer32_[version].dll (32-bit version)

1.2 From Google Chrome

Canary channel:
Optionally, get the Flash version number:
(If you want to see the correct version number on Chromium internal pages)
  • On all platforms, open the manifest.json text file in the PepperFlash folder.
  • On Windows, you can do a right-click → Properties → Version, on the .dll file

2. Change the plugin directory

If you want, prefer a short path for the plugin. It will be easier for the next step. ^^
Example on Windows: Put this .dll file in a path like C:\PepperFlash\ (Create the directory if needed)

3. Add command-line flags

By default, Chromium does not know PepperFlash exists.
Use these #command-line-flags:
  • --ppapi-flash-path=[plugin path]
  • --ppapi-flash-version=[plugin version]
  • And optionally --allow-outdated-plugins to disable browser notifications about outdated plugins

On #windows, create a Chromium shortcut. Then go to its properties and edit the target field: --ppapi-flash-path="C:\PepperFlash\pepflashplayer.dll" --ppapi-flash-version="" --allow-outdated-plugins
On #mac, you will need to launch it from the command-line (in the Terminal): /Applications/ --ppapi-flash-path=/Library/Internet\ Plug-Ins/PepperFlashPlayer/PepperFlashPlayer.plugin --ppapi-flash-version= The "&" at the end is not a typo. It is there to make sure Chromium is launched in a separate thread. Without the "&", Chromium would exit as soon as you quit the Terminal. Moreover, to simplify the Chromium launch, check How to create simple Mac apps from shell scripts (Archive: 1). Also see the #comment-566 and #comment-344.

4. Restart the browser

Relaunch it to apply changes.

5. Check the installation

6. Enjoy!

Now, even after browser updates, Chromium uses PepperFlash. ^^

NPAPI plugin support

Chromium build 45.0.2416.0 (331982) is the last version which still has NPAPI plugin support enabled via chrome://flags or group policy registry. (sourceNPAPI deprecation)

Solutions to still use NPAPI plugins:
  • Switch to another browser like Firefox (Firefox: info about plugins, NPAPI deprecation)
  • or install an older Chromium version (Ex: 331982, 331959, 331938, 331935...)
  • or install the IE Tab addon which allows users to view pages using the IE layout engine

More info on site archives:

HTML5 audio/video

By default, Chromium does not support proprietary codecs (AAC, MP3, H.264/MP4) in the HTML <audio> and <video> elements.

  • On #windows, use Nik builds. All codecs are enabled ^^
  • or compile Chromium from #source-code
  • or install an older version having ffmpegsumo file (Ex: 333350, 333334, 333283, 333258...)
  • or choose other #browsers
  • On #linux, you can use Chromium with proprietary codecs

Before 4 June 2015, we used an alternative with the Google Chrome ffmpegsumo file and our Patch HTML5 Media extension. More info on site archives:

1. Check HTML5 audio/video support

If there is a video issue, disable hardware acceleration (see #browser-crash).


1. Internal pages

To access to all internal pages, use chrome://about. Copy and paste this special URL directly into the address bar (omnibox).
Obviously, this special URL works only in Chromium and Google Chrome.

Few internal pages:
Note: About configuration settings, there is nothing similar to Firefox's about:config in Chromium.

Example: How to clear DNS cache?
Open chrome://net-internals/#dns and click on the Clear host cache button.

2. Keyboard shortcuts

To use keyboard shortcuts (on Windows, Mac and Linux), check this full list of official shortcuts... and this one if you are developer. Most of the shortcuts are similar to IE, Firefox or any other browser.

3. User data directory

About your bookmarks, profile... it is important to know where is stored your user data

4. Command-line flags

There are command-line flags (or "switches") that Chromium accept in order to enable particular features or modify otherwise default functionality. Note flags often contain experimental or obsolete code, so they tend not to stick around for long.
Example: How to start Chromium directly in incognito (or private) mode on Windows?
Add flag at the end of the Chromium shortcut and restart the browser. (screenshot)
"C:\{...}\Chromium\Application\chrome.exe" --incognito

5. External extension installation

How to install an external brower add-on?
  1. Get source .crx file of any extension directly from the Chrome Web Store via CRX Viewer or via a site like Chrome Extension Downloader, Crx4Chrome
  2. Go to chrome://extensions
  3. Drag and drop the .crx file on the page

If it does not work...
  1. Unzip the .crx file
  2. Go to chrome://extensions
  3. Drag and drop the unzipped folder on the page... or click on Developer mode then Load unpacked extension...

About updates:
  • You have to update manually
  • You can update when you want! ^^
  • If ever a new version sucks, just re-install the previous one

6. Source code

Before all, check the official guide for developers

Official links to easily get or see the full Chromium source code:
Interesting info:

7. Older version

Never update your browser with a very old version. It even does not start.

To install an older Chromium version:
  1. Uninstall your actual version
  2. Destroy the main folder, the #user-data-directory (and the registry entries, on Windows)
  3. About official builds, get your older version from the → download/ page or the Snapshots repository
  4. Install it. Enjoy!

8. Browser crash

You have encountered a browser crash or issue :/

Few ways to help you:
- To disable hardware acceleration: - To disable/enable a browser feature: chrome://flags
- To disable plugins: chrome://plugins
- To check for conflicting software: chrome://conflicts
- To disable extensions/add-ons: chrome://extensions

Also you can use #command-line-flags: --disable-extensions, --disable-gpu, --disable-accelerated-video-decode...
Note that incognito mode disables all extensions by default.


This is a free and simple API for developers to update Chromium to the latest good build via a bash (shell) script, an add-on... Read my #notes.

Please, do not use this API to build other websites. To prevent abuse, the site can audit each API request.

GET request parameters:
  • os(required) windows or mac or android
  • bit(optional • 64 by default) 64 or 32
  • out(optional • json by default) json or string or xml or revision

Open-source browsers:
Proprietary browsers:
  • Vivaldi (based on Chromium • by Vivaldi Technologies)
  • Opera (based on Chromium • by Golden Brick Silk Road/Qihoo 360, since July 2016)
  • Chrome (based on Chromium • by Google)
  • Safari on Mac (by Apple)

I do not recommend:
Why not recommended?
Because all of these browsers are closed-source, outdated and based on Chromium like Google Chrome and Opera... and most of the features they remove don't even exist in Chromium, in the first place. Control your personal info and #privacy yourself ^^

Moreover, InsanityBit explains this very well on his blog: SRWare Iron Browser – A private alternative to Chrome? (2012 • Archives: 1, 2)

Note if a new browser with "better privacy" than Google Chrome is based on Chromium and is fully open-source, it should be ok for me. But... Google is famous. Its private policy and marketing strategy are well known. So you have to ask you some questions. Do you trust in an unknown team more than Google? Is an outdated Chromium fork?
Few free and open-source Chromium forks:


For a better privacy protection, use open-source #browsers like Chromium or Firefox. Do not forget: It is open-source does not mean it is secure and respects user privacy (and security ≠ privacy). But, if your browser is fully "open-source", it means that somebody with the capability can review the #source-code. With versioning tools like SVN or Git, it is easy for developers to find malicious code (Ex: Chromium downloads a Chrome extension as a binary without source code). Only an open-source code allows such defense. This is better for secure browsing and user privacy. While I recommend Firefox as the most reliable browser for privacy enthusiasts (cf. about:config settings), Chromium is probably a reasonable alternative for everyday web browsing.

1. Browser update

The reason for updating to the latest version is security. As security threats are found, they are fixed. Using an old version may expose user to a number of security issues. Browsers are far more subject to hacking than other software.

2. Browser settings

Adjust all settings and advanced settings in chrome://settings:

3. Hosts file

Modify your hosts file to prevent your OS from connecting to domains who serve ads, spyware and malware. This will increase your OS security and save bandwidth.


4. DNS services

By default you are using the DNS servers of your ISP but you do not have to stick with them. Free alternative Internet DNS services for personal use:

5. Search engines

Choose a web search/metasearch engine which respect your privacy:

6. Extensions

Note: Extensions hosted on Chrome Web Store are updated via the Chrome update mechanism (cf. Chromium source code) which developers and users do not control. For a manual installation, read the #external-extension-installation part.

For Chromium (and Firefox):
  • Browser VPN: Do not use Hola! or ZenMate. Hola! is a botnet (more info on 8chan). ZenMate needs a free user registration. (Prefer to pay for a safe and secure VPN service... or use a free VPN service without registration)
  • If you use Adblock Plus or AdBlock, disable "Acceptable Ads" option.
  • µBlock Origin (wiki) is pattern-based filtering, while µMatrix (wiki) is matrix-based filtering which gives you more control over the filtering process.
  • µBlock Origin and ScriptSafe can also protect against WebRTC IP leak.

Reputable and reliable sites to show or prevent user data tracking:


You have downloaded Chromium and your antivirus detect a malicious software like a virus or trojan. It is a false positive. The detection is generic (heuristic). There is absolutely no backdoor or other malware inside. Remember that the full #source-code is available! More on #privacy...

These reports are known for few years ago:
  • Make sure you download Chromium from reliable sources (like on this site ^^)
  • Prefer an open-source #updater

If you find an issue:
  • Contact your anti-virus or anti-malware support
  • Report it on the official Chromium supports. For links, see my #comment-1 below.

Chromium updater

To update Chromium automatically.

As always, never install a closed-source software especially if you have never heard it before! SearchCode, GitHub (and its Gist service) are good places to find good stuff. So, try these open-source Chromium updaters:

Thanks a lot for developers!
I do not support these tools. Please, contact the developers for thank, issue, help...

'Aw Snap!' error seems to be caused by chrome://flags/#enable-asm-webassembly flag, so if someone has it enabled disable it.
Also on the newest 57.0.2935.3 Canary build there seems to be a problem with Reddit Enhancement Suite, you get 'Aw Snap!' errors while browsing Reddit with this extension.

Tried disabling this as per other posts. chrome://flags/#enable-asm-webassembly
Also tried resetting all flags to defaults. Several sites still 'Aw Snap!'.
This is annoying
@nik: Testing your latest No-Sync build and I'm unable to enable pdf-plugin, it's grayed out with a message "Disabled by enterprise policy".
@This is annoying: what arch? i'm using right now the latest lkgr build 2933 64-bit and pdf is work
@Spring & @Nik The borders are gone in my latest Clang build, which I should have ready for release later tonight.

I did not notice the borders when instrumenting my latest PGO build, either. It is currently in phase two building, so it probably will be late tonight or tomorrow before releasing it.

I think the recent crasher now should be resolved, too. :)

@RobRich, your builds have the 'all-codecs' like Nik's builds?

thx for the builds Rob and Nik.
I build with the default open source and branded proprietary codecs enabled using predefined GN build system parameters.

I think Nik builds with all codecs available, including those in the codebase perhaps needing build file edits to manually enable, so there could be differences.
Just want to share:
I just tried to upgrade Chromium portable (regular dev) from 57.0.2929.0 to 57.0.2939.0 and get this message on start up:

Failed To Create Data Directory
Chromium cannot read and write to its data directory:


The portable configuration are the same, so it's kinda weird. But maybe more luck with latest release so I tried with 57.0.2940.0, but no luck!

I thought it was the portable configuration, but when I run the last release (57.0.2929.0), surprisingly it's OK no strange error message.

Happen both on 32 and 64 bit. Anyone with the same experience?

@versapps Same here.
It's a bug
Fixed soon.

Why the newer Chromium doesn't contains flash plugin? I don't want to install flash into my system. I'd be happy to have it only in Chromium.

@1592: use chrlauncher with PPAPI plugin ^^

@1593. Thanks. But I forgot to mention Chromium for macOS.

Just install and tested No sync • No WebRTC • No Widevine • 55.0.2883.75 (423768) • Friday, 2 Dec 2016
ALL GOOD and somehow is much much more blazing fast-er than b4
still i pref the old non-Material Design User design - which ver is the last copy again pls?
Thanks for your good work
Also thanks jerry for your site
@1595: i think it's the 54.0.2840.99
@all: I'm thinking to drop the NOSYNC build (and it's great that RobRich doing dev builds) and keep only SYNC build. The reason for that is time, when a single non-PGO build lasts for ~1.5 hours (and both only ~3hours), a PGO build takes ~8-9 hours on my pc (i have 32gb of ram) and both (sync and nosync) pgo builds lasts for 16-18 hours :(
so something like this..
Anonymous (1598)
do you have more user for nosyc or sync?
i pref nosync
perhaps you can do a alternate ver - sync when 54.0.2840.99 then nosync when 55.0.2883.75
or like once a month or couple of months or even quater or half-yearly - like a major upgrade...
not sure if the everyday user needs to update ver everytime chorme new release
unless there is a major bug
so pls consider keeping the nosync (be it not regular updates)
appreciate your work and time :)
@Anonymous, thanks for the bug link :)

@Nik. Yes! Let Rob do the NoSync.
Kind of hoping no-sync doesn't get dropped. It's the only active builds of chrome/chromium without webrtc (prevents IP leak...etc).
Is it possible to keep no-sync, but just compile without PGO (like you used to)?
Anonymous (1601)
I also prefer NoSync. Hell.. if the choice was between using Sync and using NoSync without PGO, I'd rather see PGO dropped than the entire build.
Looking at PGO build stats, only around 0.2% of functions are compiled for speed. The vast majority are compiled for size, which likely is not much of a concern for modern systems with plenty of memory.

I suppose there is the issue of cold and dead paths, but again, I supect most of us are running systems with plenty of memory and probably processors with decent cache sizes.

Point? PGO is not a tremendous performance improvment on decent hardware compared to full WPO, which uses heuristics instead of instrumented profile data for optimization. Full WPO is build intensive, as PGO uses it too, but it does not require instrumentation profiling or second phase linking - a potential build time savings of several hours.

I know Pale Moon (forked Firefox) dropped PGO, and IIRC, the decision was made quite a long time ago. I suspect it might have been done due to similar results as we are noting here.

I have an updated PGO build that just completed last night. I can do a full WPO build easily enough. How about I then post both bulds, and a few of us comparison test them for feedback on any actual usability peformance differences?

In terms of daily usage, snapshot dev and even my own Clang dev builds peform decent enough - IMO anyway - on my various systems, including my older notebook with an early AMD A10 processor.
