About this site
Favorites File does two things, and they share a name for a reason.
The tools
Free utilities for the file your browser keeps your bookmarks in: find the links that have rotted, collapse the duplicates, merge exports from browsers and machines you've long since stopped using, and convert the whole thing into something a spreadsheet or a notes app can read. Alongside them, guides to where that file actually lives on every platform, and how to get it back when it disappears.
All of it runs in your browser. There is no upload endpoint, no account, and no server-side copy of anything you drop in — the JavaScript reads the file on your machine, renders the results locally, and generates any download locally too. Close the tab and it's gone.
That isn't a marketing position, it's a design constraint we accepted costs for. It's the reason the dead link checker can tell you a domain is gone but can't tell you a page returned a 404: reading a status code from another site requires a server making the request, and a server making the request requires your bookmarks. Every browser you've ever used has been carrying a list of everything you read, bank with and shop for. It doesn't need to be uploaded to be de-duplicated.
The File
The other kind of favorites file: a dossier on one category at a time, with the rejects published alongside the picks. Some of those links earn a commission — how that works — and none of them decide what gets recommended.
Corrections
If a path in a guide is wrong, a tool mangles your file, or a recommendation doesn't hold up, say so and it gets fixed. Bug reports that include the browser and what the file came from are especially welcome. Never send the bookmark file itself.
