Connected browser-local PDF workflow

v10.84 connects page organization, merge/split, rotation/deletion/extraction, conversion, compression, annotation, forms, metadata, page sizing, N-up/booklet/poster printing, comparison, and repeated header/footer work without replacing the established historical PDF engines.

PDF processing boundaries

These tools operate within browser memory and the capabilities of pdf-lib/pdf.js and the existing local engines. 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.

Practical tips and limits

Keep the original PDF before editing or splitting. Browser memory and PDF features vary, so visually inspect the exported result before sharing it.
