About this tool
Watermarks serve as a visual label on every page of a document — marking it as a draft, confidential, a proof copy, or associating it with a brand or author. Add Watermark to PDF stamps either a text string or an image onto every page, with full control over position, opacity, rotation, and tiling.
For text watermarks, choose the font size, colour, and angle. A diagonal 'DRAFT' stamp across the centre is a few clicks. For image watermarks, upload a PNG (transparent backgrounds are respected) or a JPG logo. Place it in a corner as a branding mark, or tile it across the whole page at reduced opacity for a more thorough coverage pattern. You can restrict the watermark to specific page ranges if only some pages need marking.
Watermarks are added as a content layer on top of the existing page, which keeps them easily visible and readable. Because the tool runs in your browser, confidential drafts are watermarked locally — the file content is never sent to an external service.
