Chrome Extension Source Code Downloader
Download a Chrome extension's source code as a .zip from its Web Store link or ID. Pixellize converts the .crx to a clean ZIP so you can read the manifest, scripts, and CSS.
How to download a Chrome extension's source code
Copy the extension link or ID
From the Chrome Web Store page, copy the full URL or just the 32-character ID (the letters a to p at the end of the link).
Click Get source to build the ZIP
Pixellize downloads the .crx, runs the crx to zip conversion, and shows a download button, no install and no sign in.
Download and open the .zip
Click Download, then unzip the file to read the manifest, scripts, CSS, and HTML source on your computer.
Download Chrome extension source code as a .zip, free
Want to download a Chrome extension’s source code? Paste the extension’s Chrome Web Store link or its 32-character ID, click Get source, and Pixellize hands you the files as a plain .zip. Inside you will find the manifest.json, the background and content scripts, the CSS, the HTML pages, and the images, the same files the extension runs.
A Chrome extension ships as a .crx package, which is really a ZIP with a short signed header on the front. That header makes some unzip tools choke, so Pixellize does the crx to zip step for you and gives you an archive that opens anywhere. The package is pulled from Google’s public update endpoint, the same one Chrome uses to install an extension, which is why a browser cannot download the crx file on its own, cross-origin rules block it. Use the source to audit what an extension really does before you trust it, to study how a feature was built, or to recover your own published code. Respect each author’s license and copyright.

Download Chrome extension source code: FAQ
How do I download a Chrome extension's source code?
Paste the extension's Chrome Web Store link or its 32-character ID, then click Get source. Pixellize downloads the package from Google, converts the .crx to a ZIP, and gives you a download button. Open the .zip to read the source. No sign in or install is needed, and it takes one click.
Can I download a Chrome extension as a ZIP instead of a CRX?
Yes. Pixellize returns the source as a plain .zip, not a .crx, so there is no header left to strip. Open the ZIP on your computer to see every file: the manifest.json, background and content scripts, stylesheets, HTML pages, and images from the extension.
How do I convert a CRX file to ZIP?
A .crx file is a ZIP with a small signed header added to the front, which some tools refuse to open. Pixellize removes that header automatically and gives you a clean ZIP, so you do not need a separate crx to zip converter. The download is already a standard archive.
Can I view a Chrome extension's source code without installing it?
Yes. You download a ZIP of the source files to your computer and read them in any editor, so the extension is never added to Chrome. It is a safe, read-only way to see what an extension contains before you decide whether to install it.
Where do I find a Chrome extension's ID?
The ID is the 32-character string of letters a to p at the end of the Web Store URL, right after the extension name. Paste the whole URL and Pixellize pulls the ID out for you. For example, in chromewebstore.google.com/detail/name/ID, the last part is the ID.
Is it legal to download a Chrome extension's source code?
Reading the code is generally fine. The JavaScript, CSS, and HTML already run in your browser and are readable once installed, and the files come from Google's public download. Copyright still applies, so use the source for security review, learning, or your own work, not for republishing someone else's extension.
