SingleFile
Saves a full web page, with its CSS, images, fonts and frames, as one HTML file you can open offline.
Why it's a strong pick
SingleFile is free and open source under AGPL-3.0, and the official site says it needs no account, no cloud service, and sends nothing anywhere. The Chrome Web Store listing shows version 1.28.1, updated 4 October 2026. Saved pages open offline without the extension. The trade-off: very dynamic pages may need a second try.
What it does
SingleFile saves a web page as one HTML file. The file holds the page's CSS, images, fonts and frames, so it looks the same when you open it later without the extension. Click the toolbar button or press Ctrl+Shift+Y. The right-click menu can also save a tab, a selection, a frame or links.
Key features
- One-file pages. The saved HTML file opens offline, without the extension.
- Annotate and save. Highlight, add notes and remove content before you save.
- Save many tabs. Save selected, unpinned or all tabs, or batch save from a list of URLs.
- Auto-save. Save pages as they load.
- Cloud upload. Optional upload to Google Drive, Dropbox, GitHub or WebDAV. The official site also lists Amazon S3.
- Self-extracting ZIP. Pack saved pages into one ZIP that opens itself.
Who it's for
SingleFile suits researchers, students and anyone who keeps offline copies of articles and receipts. You get a file you own, with no service in between. If you want to look up old versions of a live page instead, see Wayback Machine. To record a page and replay it, see ArchiveWeb.page.
Does SingleFile need an account?
No. The official site says there is "no account, no cloud service, and nothing is sent anywhere". Uploading to Google Drive, Dropbox, GitHub, WebDAV or Amazon S3 is optional, and you only use it if you turn it on. On the Chrome Web Store, the developer states it will not collect or use your data.
Does SingleFile work with Manifest V3?
It is built on Manifest V3. The project's MV3 repository, which the README calls the new version compatible with Manifest V3, has manifest_version 3 and version 1.28.1, the same as the store listing. The store page does not state the manifest version itself. The main repository's root manifest is the older one.
What permissions does SingleFile ask for?
The MV3 repository manifest lists contextMenus, downloads, storage, tabs, activeTab, scripting, offscreen, sidePanel and declarativeNetRequest, plus access to all sites. Identity, clipboardWrite, nativeMessaging and bookmarks are optional. Chrome shows the current list when you install, so read it before you add the extension.
FAQ
Is SingleFile free? Yes. The official site says "it is free and open source".
Is it open source? Yes, under AGPL-3.0, per the official site and the repository's licence file.
What is the keyboard shortcut? Ctrl+Shift+Y saves the page, per the listing.
Good to know
Let the page finish loading before you click. Clicking again cancels the save, per the listing, so very dynamic pages may need a second try. After saving, open the file once to check it looks the way you expect. A saved file is a snapshot: it does not update when the live page changes.
