Manifest V3 Ready
Google is phasing out Manifest V2 in favor of the more secure and performant Manifest V3. Our builder automatically configures your manifest.json with the correct service worker and action settings. If you need to modify individual JSON files later, you can use our JSON Formatter to keep your code clean.
Perfect for Web Apps & PWAs
Many developers use this tool to create 'wrapper' apps for their internal tools, dashboards, or frequently visited websites. By adding a dedicated icon to the Chrome toolbar, you can navigate to your favorite sites with a single click.
How to Use Website to Extension

Common questions
What is Manifest V3?
Manifest V3 is the latest version of the Chrome extension platform. It introduces significant changes to improve security, privacy, and performance, such as replacing background pages with service workers.
How do I install the generated extension?
Download the ZIP, extract it, go to chrome://extensions in Chrome, enable 'Developer mode' in the top right, click 'Load unpacked', and select the extracted folder.
Is my data sent to any server?
No. All ZIP generation and file processing happen entirely in your browser. Your website URL and extension metadata never leave your device.
Can I publish this to the Chrome Web Store?
Yes. The generated files provide a solid foundation. You may need to provide your own professional icons and possibly a privacy policy depending on the website you are wrapping.
Why does Chrome say my extension is 'unpacked'?
Extensions loaded locally via 'Load unpacked' are considered developer extensions. To remove this label, you would need to publish the extension through the official Chrome Web Store.
Does it work with Brave or Edge?
Yes! Since Brave and Microsoft Edge are built on the Chromium engine, they fully support Chrome extensions and Manifest V3.
