We're polishing this tool — read on to learn what it'll do, or try one of our working tools above.

Watermarking is how you mark a PDF as confidential, draft, or owned-by-someone before you share it. Converterzilla will let you place a text or image watermark across every page with control over rotation, opacity and position — all without uploading the document anywhere.

How to use Add Watermark in your browser

  1. Drop the PDF. Choose the document you want to watermark. We handle multi-page PDFs of any reasonable size.
  2. Set up your watermark. Type text or upload an image, then set rotation, opacity and which corner (or center) you want it placed in.
  3. Apply and download. Converterzilla stamps every page with your watermark and saves the result as a new PDF.
