SingleFile is a WebExtension compatible with Chrome, Firefox (Desktop and Mobile), and Opera that helps you to save a complete web page into a single HTML file.



Getting started

  • Wait until the page is fully loaded, you may need to scroll down the entire page to be sure all elements are loaded.
  • Click on the SingleFile button in the extension toolbar to save the page.

Additional notes

  • To save multiple tabs, select them first and click on the SingleFile button.
  • Open the context menu by right-clicking the SingleFile button in the extension toolbar or on the webpage. It allows you to save:
    • the current tab,
    • or the selected content,
    • or the selected frame.
  • You can also process multiple tabs in one click and save:
    • the selected tabs,
    • or the unpinned tabs,
    • or all the tabs.
  • The context menu also allows you to activate the auto-save of:
    • the current tab,
    • or the unpinned tabs,
    • or all the tabs.
  • With auto-save active, pages are automatically saved every time after being loaded (or before being unloaded if not).
  • Right-click on the SingleFile button and select "Options"/"Manage extension" to open the options page.
  • The default save folder is the download folder configured in your browser, cf. about:preferences in Firefox and chrome://settings in Chrome.
  • You can use the shortcut Ctrl+Shift+X to save current or selected tabs in Chrome. Go to chrome://extensions/shortcuts to change it.

More info

See the extension help in the options page for more detailed information about the options, and technical notes. See for some info about the optimizations applied to web pages.

Troubleshooting unknown issues

Please follow these steps if you find an unknown issue:

  • Reset SingleFile options.
  • If resetting options did not fix the issue, try to disable all other extensions to see if there is a conflict.
