Stamp & Sign
Photograph your stamp on paper once — then put it on any PDF with one tap.
Free, always
- A clean stamp from a photo: the app finds the ink, removes the paper, shadows and background, and keeps the colour — no sliders
- Works with the camera, the gallery and screenshots
- Draw a signature with your finger: three widths, three colours
- Tap a stamp and it lands on the page; drag it, resize it, tilt it like a real one; zoom the page with two fingers
- A new file <name>_signed.pdf in Downloads / Stamp & Sign; the text of the document stays text, the original is not changed
- One stamp and one signature, any number of documents, no watermark
- Light and dark theme, sixteen languages
- No ads, no account, no internet permission at all
Pro — one-time purchase
- Unlimited stamps and signatures
- All pages or the last page in one tap
- Many PDFs at once: the same stamp in the same place on every file

A stamp on white paper, photographed from above in daylight.
Not a digital certificate
The app places an image of your stamp and signature on the page, like on paper. It is not a certificate-based electronic signature.
Everything happens on the phone
The app has no internet permission and no camera permission: photos are taken by your phone’s camera app. Your documents, stamps and signatures physically cannot be uploaded anywhere. Check it yourself on the permissions page in Android settings.
