Processing and privacy
Document converters are typically external (Stirling-PDF). Upload limit is about 100 MB per request. Password unlock is not provided. Retention details are in the Privacy Policy. PDF Sign and PDF Page Organizer are exceptions: they run in the browser with pdf-lib and PDF.js without uploading your file.
