Watermark PDF stamps custom text across your document to mark ownership, draft status, or confidentiality. Control the font size, color, opacity, rotation, and position, and apply the watermark to every page or just a range.
Watermarking runs entirely in your browser, so sensitive drafts and internal reports never touch a third-party server. Your original PDF stays on disk unchanged, and you download a separate watermarked copy. You can preview the placement on the first page before committing, so the mark lands exactly where you want it.
How it works
Upload your PDF
Drop the document you want to watermark into the upload area or click to browse for it.
Configure the watermark
Type your text, then adjust font size, color, opacity, rotation, position, and whether it covers all pages or a page range.
Apply and download
Click Apply Watermark to render the marked PDF, then download it. The source file is left untouched.
