Add watermark to PDF
Add a watermark to a PDF in your browser — faint text or an image, single diagonal or tiled across every page. No upload, no signup.
Watermark a PDF with text or an image without uploading it. Add a single faint diagonal mark across the page, or tile the watermark in a repeating pattern over every page. Useful for labeling drafts, marking documents confidential, or adding a logo behind content. Everything runs in your browser, so the file stays private. Free, no account, no watermark on the output.
