OnyxPDF

About this product

Every 'free PDF tools' site uploads your file to their server — your contracts, bank statements and ID scans sit on a stranger's computer for a retention period you can't verify. OnyxPDF removes the server: 50 PDF and image tools run 100% in your browser via WebAssembly — merge, split, compress, convert, OCR in 7 languages, true redaction, signing, and AES-256 encryption, all on your device. No upload. No account. No cost. Test it in airplane mode — every tool still works.
