This free tool converts the bookmarks HTML backup file exported from browsers (Chrome, Firefox and others) to Markdown (.md) format.
It runs from a plain HTML file: no installation, no extensions, no command line, no permissions. Use the same browser you used to create the backup. You can also use the online version that requires no download at all.
The online version does not require downloads. It runs directly from the browser and performs the conversions locally. No data is processed on the server side, not data is collected.
