Signatur – Sign & Edit PDFs
The PDF app beyond Preview
Free · In‑App Purchases
Signatur Pro is here: 3 documents free, 7-day free trial on yearly, one purchase unlocks iPhone, iPad and Mac.
Sign every document the moment it arrives.
Signatur puts signing, verification and PDF editing in one app. Quotes, approvals, onboarding papers, agreements — any document that needs your signature gets signed and sent back in minutes, no printer, no scanner.
SIGN LIKE ON PAPER
• Handwritten signature, stamp and date — drop them exactly where they belong
• Face ID confirms before the ink lands, so every signature is yours
• Seam stamp for multi-page documents, one mark across every page pair
• Form fields detected automatically — name, date, company filled in one pass
EVERY DOCUMENT CAN BE VERIFIED
• Signed files carry an invisible watermark — if anything changes, one check reveals it
• Verification is free forever for anyone you send files to, no account needed
• Optional scannable QR receipt in the corner that survives printing
MORE THAN PREVIEW
• Merge PDFs, password-protect files
• Redact sensitive content for real — removed, not covered
• Page tools: delete, rotate, reorder
• Scan paper with the camera, stitch chat screenshots into a PDF
BUY ONCE, USE EVERYWHERE
One purchase unlocks iPhone, iPad and Mac. Sign on your phone, keep editing on your Mac.
YOUR FILES STAY ON YOUR DEVICE
Signing, watermarking and verification all happen locally. There is no server holding your documents — by design.

• Yearly — 7 days free, a reminder 2 days before any charge, billed only if you stay
