Add a text or image watermark in seconds. Pick the typography, transparency and position, see it live on your page, then download. It all happens inside your browser.
or choose a file from your device
It opens straight in the page using your browser's own PDF engine. No network request involved.
Type text or add an image, then adjust font, colour, transparency, size, rotation and position. The preview updates as you go.
The watermark is written onto the chosen pages on your device, and the new PDF saves like any other download.
Contracts, proposals and unreleased work never pass through a third party's server just to get a "DRAFT" stamp.
The tool builds a new file. Text and images in the pages stay as they were, and text stays selectable.
Processing uses your own device, so there is no upload cap, queue or account.
No. The file is opened and stamped inside your browser tab. Nothing is sent to a server, and closing the tab discards everything.
Yes. The tool adds the watermark on top of the existing pages instead of redrawing them, so original text, links and images are kept. Watermark text in the classic fonts is also real, selectable PDF text.
For a background-style mark that doesn't hinder reading, 15–30% works well. For a clear stamp such as "APPROVED", try 50–80%. The live preview shows exactly how it will look.
PNG, JPG, WebP, GIF and SVG. A PNG with a transparent background gives the cleanest result, because only your logo or signature is drawn, not a white box.
Yes. Choose all pages, the first page, odd or even pages, or a custom range such as 1-3, 5, 8-, where "8-" means page 8 to the end.
Yes. Choose "Repeat across page" to tile the stamp in a staggered pattern. Lower the size slider for a denser pattern.
Yes. Classic fonts are embedded as real PDF text when your text uses standard Latin characters. For other scripts, accents outside that set, emoji, or the designer fonts, the watermark is drawn as a sharp, high-resolution image instead.
A watermark is a visual deterrent, not security. Someone with a PDF editor may be able to remove or cover it. For stronger protection, combine it with a password or permissions in a dedicated PDF security tool.
Yes. The stamp is positioned relative to the page as you see it, including landscape pages, rotated pages and PDFs with cropped page boxes.
Password-protected files must be unlocked first. Corrupted files may not open either. Very large files can also be slow on phones, because everything runs on your device's memory.
Once the page and its PDF libraries have loaded, watermarking does not need the network again.
