Chrome vs Chromium: What's the Difference?

Chromium is the open-source browser project. Google Chrome is a product Google builds on top of Chromium and ships with extras. Both use the same rendering engine, so web pages look and behave almost identically. The differences are in what Chrome adds: extra media codecs such as H.264 and AAC, Google's branding, tested and signed releases and, depending on the platform, automatic updates and Google services.

For everyday browsing, pick Chrome. For open-source builds, Linux distributions, or developer tooling that bundles a browser, you will often meet Chromium. This guide lays out the real differences, what is still unclear, and how to choose, including for browser automation.

#Key takeaways

• Same engine, different packaging. Chrome is built from Chromium's code plus Google-specific additions.
• Codecs differ. Per the Chromium project's own comparison, Chrome adds H.264 video and AAC audio that Chromium does not include.
• Branding and telemetry differ. Chromium has a blue logo and never reports crashes or usage metrics. Chrome reports them only if turned on.
• Updates and testing differ. Chrome releases are tested before shipping. Chromium's testing and updates depend on who packages it.
• Many other browsers are Chromium-based. Edge, Brave and others build on the same project.

#What is Chromium?

Chromium is the open-source browser project that supplies the rendering engine, the JavaScript engine and most of the browser's code. Anyone can build it, modify it and ship it. That is why a lot of browsers share it as a base. Distributions and companies take the code, change it and package it their own way.

#What is Google Chrome?

Chrome is Google's browser. It takes Chromium's code and adds Google's own components, branding and release process, then ships it as a finished product with official installers.

#Chrome vs Chromium: side-by-side

The table below uses the Chromium project's own Linux comparison page, so some rows describe Linux specifically.

#The differences that matter most

#Media codecs

If you open a video that uses H.264 or an audio file that uses AAC, Chrome plays it and a vanilla Chromium build may not. Some Linux distributions add the missing codecs back, so your experience can vary by package.

#Updates and security

Chrome ships through Google's release process with new releases tested first. For Chromium, update speed depends on your distribution or whoever builds it. The Chromium project encourages distributions to track stable releases, but it does not guarantee they do. On a desktop you rely on, that gap is the biggest practical risk of Chromium.

#Privacy and telemetry

Chromium never reports crashes or usage metrics. Chrome reports them only if you turn the setting on. Neither is a complete privacy picture, so check each browser's settings for sign-in, sync and search features.

#Google services

Several third-party write-ups say Chromium lacks parts of Chrome's Google integration, such as sign-in and sync or DRM components like Widevine. The official comparison page does not cover those points, and they can differ between distributions, so verify them for the exact build you use.

#Chrome vs Chromium for developers and automation

Browser automation tools commonly drive Chromium builds, and some can also drive branded Chrome. For scraping, testing and screenshots, what matters is consistency: pin one browser version so results do not change under you.

Points to keep in mind:

• Codec gaps can break tests. A page that plays H.264 video may behave differently in a Chromium build that lacks it.
• Version drift causes flaky runs. Pin the version in CI rather than using whatever is installed.
• Real Chrome can behave differently from bundled Chromium on features tied to Google components, so test the browser your users actually run.

#Other Chromium-based browsers

Because Chromium is open source, many browsers build on it, including Microsoft Edge and Brave. They share the same engine, so web compatibility is similar, while features, privacy defaults and update policies differ by vendor.

#FAQ

#What is the main difference between Chrome and Chromium?

Chromium is the open-source project. Chrome is Google's product built from it, adding extra codecs such as H.264 and AAC, Google branding and a tested release process.

#Is Chromium safer than Chrome?

Not automatically. Chromium sends no crash or usage reports, but its updates and testing depend on whoever packages it. Chrome ships tested releases through Google. Security depends mostly on staying up to date.

#Can Chromium play YouTube and Netflix?

YouTube mostly works because it can serve codecs Chromium supports, but behaviour varies. Streaming services that rely on DRM or on H.264 or AAC may not work in a vanilla build. Some distributions add support, so check your build.

#Is Chrome built on Chromium?

Yes. Chrome is built from Chromium's code with Google-specific additions.

#Which browsers are based on Chromium?

Many, including Microsoft Edge and Brave. They share the engine and differ in features and policies.

#Should I use Chrome or Chromium for web scraping and testing?

Use whichever your tool pins, and keep the version fixed in CI. If your users run Chrome, test on Chrome too, since codec and Google-component differences can change behaviour.
