SnapInk: Sign PDF Documents

Sign PDF documents from your phone, with your own handwritten signature — no account, nothing uploaded.

SnapInk turns your phone into a signature stamp for any document.

Photograph your handwritten signature once. SnapInk lifts it off the paper and gives it a genuinely transparent background, so it sits cleanly on any page, on screen or printed.

SIGN ANY DOCUMENT
• Scan with the camera, or open a PDF from Files or Photos
• Place your signature, then resize and position it exactly
• Add the date, your initials, or any typed text
• Sign across every page of a multi-page document

A PROPER SCANNER
• Edges detected automatically, page by page
• Original, colour, greyscale and black-and-white modes
• Reorder, rename and delete pages before saving

NO PEN NEARBY? TYPE IT
Four handwriting styles, if typing your signature suits you better than photographing one.

EXPORT AND SHARE
PDF, JPG or PNG, at the quality you pick. Share it, save it to Files, or print it.

KEEP YOUR DOCUMENTS IN ORDER
Search, sort and group into folders. Rename, duplicate or delete anything.

YOUR DOCUMENTS NEVER LEAVE YOUR PHONE
No account. No sign-in. No server. Your signatures and your documents are stored on this device and nowhere else.

NINE LANGUAGES
English, French, Spanish, Portuguese, Russian, Turkish, Chinese, Japanese and Arabic.

SNAPINK PRO
The free version keeps one signature, allows a few exports each month, and adds a small watermark in the corner. Pro lifts all three: unlimited signatures, unlimited exports, no watermark.

WHAT SNAPINK IS NOT
SnapInk places an image of your handwritten signature on a document. It does not verify your identity, issue certificates or keep an audit trail, and it is not a qualified electronic signature service. Whether a document signed this way is accepted depends on the document and on where you are.
