Real transparency
Signatures are saved with a true alpha channel, so they sit on a page without a white box around them.
iOS · IPADOS · ANDROID
Sign anything,
anywhere.
Photograph your handwritten signature once. Then sign, date and export any document or PDF from your phone, in under thirty seconds.
Free to try. No sign-up, no email, nothing to cancel.
NO ACCOUNT
Open the app and start. There is nothing to sign up for.
ON-DEVICE ONLY
Documents and signatures never leave your phone.
9 LANGUAGES
Including a fully mirrored Arabic layout.
WORKS OFFLINE
Every step runs on the device, with no connection.
HOW IT WORKS
Three steps, and you never do the first one twice.
STEP 01
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.
STEP 02
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.
STEP 03
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.
FEATURES
Built for the paperwork you actually get sent.
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, so nothing lands crooked or half off the line.
Dates, initials and text
Fill in the rest of the form in the same pass, without exporting to another app and back.
Export by file size
Each quality option shows what it will actually produce — about 320 KB, 1.2 MB, 4.8 MB. Share, save to Files, or print.
Nine languages, properly
Arabic runs in a fully mirrored layout, not a translated left-to-right screen with the words swapped.
ALSO ON IPAD
The same app, with more room to work.
SnapInk runs natively on iPad and Android tablets — it isn't a phone screen stretched to fit. Document grids pick up extra columns, forms stay a comfortable width instead of spanning edge to edge, and the scanner and signature editor get the same extra space.
- Native iPadOS and Android tablet layouts, not a scaled-up phone view
- Full-size scanner and signature editor
- Same on-device privacy and offline signing as the phone app
BUILT RIGHT
Light mode, dark mode, and accessibility aren't an afterthought here.
We're strict about this. Every screen ships in both themes, and every colour pairing is checked before it ships — not eyeballed after.
Both themes, properly
- Follows your phone's appearance setting the instant it changes
- Every screen is designed and reviewed in light and dark, not just re-tinted
- Force light or dark from Settings if you don't want it to follow the system
Accessibility, checked automatically
- Every text and UI colour pairing is tested against WCAG AA contrast, in both themes, on every build
- Every tappable control is at least 44pt, with extra invisible hit area on small ones
- VoiceOver and TalkBack labels on every control, and layouts that hold up under Dynamic Type
PRIVACY
There is no account, and there is 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

SUBSCRIPTION TERMS
SnapInk Pro is purchased inside the app, not on this website. It starts with a 3-day free trial. Unless you cancel at least 24 hours before the trial ends, it converts to a $9.99 weekly subscription and renews every 7 days until cancelled. Your store account is charged within 24 hours of each renewal. Manage or cancel the subscription in your App Store or Google Play account settings — deleting the app does not cancel it. Prices are in USD and may differ by region and store. Payment is taken by Apple or Google, not by us.
Sign the next one from your phone.
Free on iPhone, iPad and Android. No account, and nothing to set up before you start.
