SingleFile is a very useful extension for most mainstream web browsers that lets you save the entire contents of what you currently see in your web browser tab (or tabs) to a single HTML file. Great for archiving pages you don’t want to risk losing to the mists of linkrot.
It saves what you see, so is fine for pages on sites you have to be logged in to see.
SingleFile is a browser extension that allows you to save an entire web page, including all its resources (e.g., images, stylesheets, fonts, frames, etc.), as a single HTML file with just one click.
The saved page can be displayed offline in any browser without needing to install any extension. Ideal for researchers, students, and professionals needing reliable offline copies of web pages, or for anyone wanting to keep a record of their favorite web content.
SingleFile is available for Chrome, Edge, Firefox, and Safari. It is free and open source.
