Portmarks lets you create portable HTML bookmark files for any web page. Your bookmarks work everywhere—no browser sync, no cloud dependency, just tiny files you own. Free and open source.
- Own Your Data: Bookmarks are saved as local HTML files. You have complete control, with no cloud dependency, tracking, or accounts.
- Universal & Portable: Works in any browser on any OS. Organize your bookmarks in folders, sync them via cloud storage, or share them anywhere.
- Simple & Private: Installs as a lightweight bookmarklet that runs entirely in your browser. The process is completely offline and private by design.
Portmarks generates a minimal HTML file with a .portmark.html extension. This dual extension ensures it's recognized as a standard HTML file by your system while also indicating its origin from Portmarks.
The core design principle is to be as tiny and universal as possible. The entire file is a single line of HTML, containing only the essential meta refresh tag needed to redirect your browser.
Here is an example for https://example.com:
<html><head><meta http-equiv="refresh" content="0;url=https://example.com/" /></head><body></body></html>
- Download the Portmarks bookmarklet from GitHub Releases and unzip it.
- Open the
install.htmlfile in your browser. - Drag the Portmarks button to your bookmarks bar.
- Click the bookmarklet on any page to download a portable bookmark file.
