SnapInk Signature App

Sign anything, anywhere. Photograph your handwritten signature once. Then sign, date and export any document or PDF from your phone, in under thirty seconds. HOW IT WORKS 1. Photograph your signature — sign a blank sheet of white paper and hold your phone over it. SnapInk finds the edges of the page and lifts the ink off it. 2. Get a genuinely transparent mark — the paper is removed, not painted over with white. Adjust the threshold and stroke weight until it looks like your pen, then save it. 3. Place it, date it, export it — open a PDF or a photo, drag your signature onto the line, and share a flattened file. Your saved signature is reused from here on. BUILT FOR THE PAPERWORK YOU ACTUALLY GET SENT • Real transparency — signatures are saved with a true alpha channel, so they sit on a page without a white box around them. • A scanner that comes with it — photograph a paper document, straighten it, reorder the pages, and get a clean multi-page PDF. • Snaps to the signature line — drop the overlay near the rule on the page and it aligns to it. • Dates, initials and text — fill in the rest of the form in the same pass. • Export by file size — each quality option shows what it will actually produce. • Nine languages, properly — including a fully mirrored Arabic layout. PRIVACY: NO ACCOUNT, NO SERVER Your signature is one of the few images you should never upload. SnapInk keeps every document and every signature on your device. Nothing is synced, nothing is backed up to us, and there is nothing on our side to lose. • No sign-up • No cloud storage • No document analytics • Works fully offline PRICING Free to try — one saved signature, the full scanner and editor, three exports a month with a small watermark.
