While precompiled binaries are available for Google Chrome for Windows, Mac, Linux, Android, and iOS, the Chromium browser does not release official binaries; users can either build from source or find downloadable binaries from other sources such as Ubuntu’s official repositories or third-party websites. The most common reason Chromium users cite for their preference of the browser over Google Chrome is better privacy — Chrome includes some trackers that send anonymized usage data to Google.
DIFFERENCE BETWEEN CHROME AND CHROMIUM:
|License||MIT License, BSD License,LGPL, MPL/GPL/LGPL, and MS-PL.||Free under Google Chrome Terms of Service|
|Developer||The Chromium Project||Google Inc.|
|Flash player||Not built in; requires a plugin||Plugin is built-in; can be disabled|
|Media codecs supported||Vorbis, WebM, Theora||Vorbis, WebM, Theora, AAC, MP3, H.264|
|Related software||Chromium OS||Chrome OS|
|PDF viewer||Not built in; requires a plugin||Plugin is built-in; can be disabled|
Chrome includes a variety of closed-source bits that Chromium lacks:
1. AAC, H.264, and MP3 Support: Chrome includes licensed codecs for these proprietary media formats, giving you access to a wider variety of media content — particularly sites using HTML5 video to stream H.264 videos. Both browsers include the basic, free codecs: Opus, Theora, Vorbis, VP8, VP9, and WAV.
2. Adobe Flash (PPAPI): Chrome includes a sandboxed Pepper API (PPAPI) Flash plug-in that Google automatically updates along with Chrome. This is the only way to get the most modern version of Flash on Linux. Even on Windows and Mac, you’re better off with the sandboxed PPAPI Flash plugin from Chrome than the older NPAPI Flash plug-in available from Adobe’s website. (You can actually get a Pepper Flash plug-in from Chrome and then install it and use it in Chromium if you like.)
3. Google Update: Windows and Mac get a program that automatically keeps Chrome up-to-date. Linux users use their standard software management tools.
4. Security Sandbox (?): Google also notes that some Linux distributions may disable Chromium’s security sandbox, so you’ll want to navigate to about:sandbox in Chromium to ensure the sandbox is enabled and functioning by default. This is one of the Chromium (and Chrome’s) best features.
While it’s not Google-branded, Chromium is still very Google-centric. It contains the same sync features found in Chrome, allowing you to log in with a Google account and sync your data.
Chromium for Linux community builds:
Linux distributions like Ubuntu offer Chromium binaries in their public repos (repositories) or sometimes bundles with the distro as pre-installed software. Debian, FreeBSD, Lubuntu, Puppy Linux and Ubuntu offer Chromium as available or default web browser. Arch Linux and Gentoo Linux set Chromium as an official repository while being an unofficial repository for Fedora.
Some developers maintain forks of Chromium that offer more features. Joli OS offers a rebranded version called Nickel.
Devices using Chromium and Chrome:
Google Chrome and Chromium are available not just for laptops and desktops but also for tablets and Android and iOS smartphones. Chrome is now the default browser on Android phones. Chrome is available for non-RT Windows 8 devices both as a traditional app and a “metro” app. A version of Chrome is also available for iOS. Availability on such a plethora of devices lets Google offer some features with Chrome that are not available on Chromium, notably syncing via “Sign into Chrome”. Users can seamlessly access their open tabs on one device when they move to a different device, as long as they are signed in (to the Chrome browser, not just to Google.com) using the same Google account on both devices.
Chromium also runs on mobile devices with its availability for Android, MeeGo’s netbook version and Maemo 5 mobile OS for Nokia.
Which one should you use?
Chromium is nice because it allows Linux distributions that require open-source software to package up a web browser that’s almost identical to Chrome and ship it to their users. Such Linux distributions could even use Chromium as their default web browser instead of Firefox if they liked — and some do.
If you’re into open-source software and try to avoid any closed-source bits, Chromium is a good option for you.
However, many Linux users who aren’t so passionate about open-source software might want to install Chrome. Installing Chrome gets you a better Flash player if you’re using Flash and unlocks a larger amount of media content online. For example, Google Chrome on Linux can now stream Netflix videos. This requires H.264 support for HTML5 video.
On Windows and Mac, the choice is clear — Chromium is too finicky to actually use as you can’t get official stable builds that will update themselves. Why not use Chrome?
I hope, this (Difference between chrome and chromium) tutorial helps.
