PDF processing boundaries

These tools operate within browser memory and the capabilities of the browser PDF libraries used on this page. Encrypted, malformed, scanned, XFA, unusual forms, complex signatures, OCR-dependent documents, and advanced desktop-editor features can require specialist software. Always verify generated files before discarding the source.
