SnapInk: Sign PDF Documents

Open any photo from your library and sign it — including the HEIC shots an iPhone takes. No pen nearby? Type your signature in one of four handwriting styles.

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.
