How to add a watermark to a PDF online
Upload your PDF using the box above, choose whether you want a text or image watermark, pick a position, then click Apply Watermark. The watermark is stamped onto every page and your new PDF downloads automatically.
Can I use my own logo as a watermark?
Yes. Choose the Image option and upload a PNG or JPG — a transparent PNG works best so the watermark blends into the page rather than covering it with a solid box.
💡 Tip: marking a draft as confidential? A light, semi-transparent text watermark like "DRAFT" or "CONFIDENTIAL" in the center of the page is the most common choice.
