Do I need to pay or register?

No. Every tool on this site is free, with no account, no email and nothing to install.

Which file types does Detect PDF Fonts accept?

The drop area takes PDF. Files are read from your device in the browser, so the format has to be one a browser can decode — that is why the accepted list on this page is finite and honest rather than "everything".

How big a file can I use?

Up to 100 MB per file and 50 files per batch. There is no server queue behind that limit; the practical ceiling is your browser's memory, so split unusually large documents into two runs.

Does my file get uploaded?

No. The page reads the file through the browser's own file API and processes it in the tab. Closing the tab discards the working copy, which is why there is no storage to clear and no retention policy to read.
