PDF clean & stamp

ClariPage

Clear overlay marks from PDFs, stamp your own, and sharpen a dull scan — all on the phone. A phone scan of a salary slip comes out grey, shadowed and crowded with marks from the last copier. ClariPage cleans the page, lets you stamp a copy, and whitens the paper, without the file ever leaving the phone.

Where it helps

The scan with a grey background

Deep clean fades grey backgrounds and light marks on scanned pages, with a live preview before you commit. Smart clean removes overlay marks, stamp annotations and mark layers from PDFs that have a text layer, and leaves the text selectable.

The copy that needs a stamp

Choose from twelve presets such as Approved, Paid, Draft and Certified true copy, or type your own text in any language, or use a logo. Diagonal, tiled or rubber-stamp seal, with colour, opacity, size, angle and an optional date, and it stays upright on rotated pages.

The photo of a document that looks dull

Enhance Scan removes shadows and yellowing, whitens the paper and darkens the ink. Pick colour, grayscale or black and white, and compare before and after.

What it does with your data

Your PDFs, images and logos are processed on the phone. No document is uploaded, and there is no account or sign-in.
The free version shows ads from Google AdMob. The Google Mobile Ads SDK may collect your advertising ID, approximate location from your IP address, app interaction and diagnostic data. Where consent is required, such as the EEA and UK, you are asked first, and you can change your choice under Settings, Ad privacy choices.
The internet permission is for ads and Google Play purchases only. Your documents are never sent.
ClariPage Pro is a one-time Google Play purchase, shows no ads and is restored with your Google account on a new phone.

Good to know

Please use ClariPage only on documents you own or are authorised to modify. It is in closed testing on Google Play now; the public listing will be linked here when it opens.
