What is SingleFile?

SingleFile is a free, open-source browser extension by developer Gildas Lormeau that saves a complete web page — CSS, images, fonts, and frames included — as one self-contained HTML file you can open offline in any browser. It runs on Chrome, Firefox (desktop and mobile), Edge, Safari, Brave, Vivaldi, Opera, and other browsers, and a companion CLI tool exists for scripted archiving. Beyond one-click saves, it can batch-save multiple tabs, auto-save specified tabs, save selections or frames, and annotate pages with highlights and notes before saving. Files land in your downloads folder by default, or upload to Google Drive, Dropbox, GitHub, or a WebDAV server. It is a mature, actively maintained project (22k+ GitHub stars, AGPL-3.0 licensed) with around 600,000 Chrome users.

Best for

People who want faithful, offline, self-hosted copies of web pages — researchers, archivists, and privacy-minded users who prefer plain HTML files they own over saving into a proprietary app.

Entirely free and open source (AGPL-3.0) with no account required
Output is a single standard HTML file that opens in any browser, forever
Very broad browser support, from Chrome and Firefox to Safari and Brave
Mature and actively maintained, with 22k+ GitHub stars and frequent releases

Cons

Pages that depend heavily on JavaScript or DRM-protected content may not capture perfectly
No native mobile apps; mobile use is limited to browsers that support extensions, such as Firefox for Android
