Stamp & Sign: PDF Signature

Stamp & Sign puts your real stamp and signature on any PDF — contracts, invoices, forms, reports — right on your phone. Photograph the stamp on paper once: the app removes the paper and keeps the ink, with a transparent background. Then open a document and place it in two taps. WHAT IT DOES Turns a photo into a clean stamp. The app finds the ink by itself, removes the paper, shadows and background, and keeps the colour. No sliders. Works with photos from the camera, the gallery and screenshots. Draw a signature with your finger: three widths, three colours. Keeps them in My stamps and signatures — open the app and they are right there. Tap a stamp and it lands on the page. Drag it into place, pull the corner to resize, tilt it like a real stamp. Saves a new file _signed.pdf in Downloads / Stamp & Sign. The text of the document stays text; the original PDF is not changed. Ink colour in one tap: as in the photo, blue, black or red. FREE, ALWAYS One stamp and one signature. Any number of documents. Share and save the signed PDF. No watermark. Light and dark theme. 22 languages. No ads. No account. No internet permission at all: nothing can leave the phone. PRO — 7 DAYS FREE ON THE YEARLY PLAN Pro by the year (7 days free to try, once per Google account), by the month or once forever — cancel anytime in Google Play. • Every page or the last one — a 290-page report gets your stamp on every page in one tap, or the signature lands straight on the last page. • Date and name — today's date, your full name or any line next to the signature, placed and moved like a stamp. • Photo of a document → sign — the contract came on paper? Photograph its pages: they become one PDF right in the app, ready for your stamp and signature. • Many PDFs at once — the same stamp in the same place on every file. • Unlimited stamps and signatures. Inside Pro there is more: send the result as one ZIP. NOT JUST CONTRACTS Any picture from your gallery can be a stamp: a logo, a PAID or COPY mark, a SALE tag. Put it on an invoice, a price list or a photo of a product — the photo becomes a PDF with your mark, ready to send or print. HOW IT WORKS Add your stamp: take a photo, pick one from the gallery, or draw a signature. Choose a PDF, or share a PDF to the app from mail, a messenger or your file manager. Tap the stamp, move it into place, tap Save PDF. Share the result or send it as a ZIP. Best results: a stamp on white paper, photographed from above in daylight. This is an image of your stamp and signature on the page, like on paper. It is not a certificate-based digital signature.
