QuickSign - Sign PDF

QuickSign makes signing documents a matter of seconds — and it all happens locally on your device.

Receive a document via WhatsApp or email sharing, "Open with," or file selection (PDF / JPG / PNG). Tap where you want to sign, sign by hand or with a saved stamp, and send back. The signed document is permanently flattened — the signature is burned into the page pixels and cannot be moved or extracted.

• Complete privacy — documents never leave your device. No server, no upload.
• Hand-signed or saved stamp signature, including signing all pages at once.
• Stamp extraction from a document photo — the white background is automatically removed.
• Add text comments in Hebrew and English, full WYSIWYG.
• Rotate pages, drag, zoom in/out, delete with undo.
• Export with sharing, save to Drive / OneDrive / any folder, or download.
• Optional backup of signatures and settings to Google/Apple/email account — not documents.

No required registration, no ads, no tracking.
