A watermark is a text or logo stamped over the content of every page — like "DRAFT", "CONFIDENTIAL" or your company logo. It marks the document's status and ownership without blocking the reading.
The opacity slider (10–100%) controls how visible the watermark is — lower values keep the document easy to read while still marking it.
Watermarking runs entirely in your browser. Your PDF and logo are never sent to any server and never stored.
Yes. Type the text (e.g. DRAFT, CONFIDENTIAL, your name or company) and it is stamped on every page. You can adjust the size, position, rotation and opacity.
Yes. Switch to the image option and upload a logo — PNG with transparency works best. It is placed on every page at the size and position you choose.
No. The watermark is drawn over the pages in a new copy — the original text, images and links stay intact and selectable. The original file is never modified.
For marking a document without hiding content, 20–40% is typical. For 'CONFIDENTIAL' stamps you want people to notice, 50–80% works well. 100% is fully solid.
Yes. The diagonal option rotates the text (or image) across the page — the classic watermark look. You can also keep it horizontal with center, top or bottom positions.
No. Everything happens locally in your browser — the file and the logo never leave your device.
