How to add a watermark to a PDF
Add your PDF and watermark
Drop in one PDF (up to 60 MB) and upload your watermark image — a PNG, JPG or WebP (a transparent PNG looks best).
Choose a mode
Quick centers the watermark on every page. Full control lets you drag to position it, resize it, and set it (or skip it) per page.
Adjust it
Set the transparency and size. In Full control, drag the watermark to place it and drag the corner dot to resize.
Apply & download
Click "Apply & download" to save your watermarked PDF.
Frequently asked questions
- Can I place the watermark exactly where I want?
- Yes — Full control mode lets you drag to move it, resize from the corner, and set a different position (or skip it) per page. Quick mode centers it on every page.
- What can I use as a watermark?
- A PNG, JPG or WebP image — a transparent PNG looks best. If your image has a solid background, the tool offers to remove it (free on your device, or a cleaner AI cut for credits).
- Can I watermark an image or Word file?
- This tool watermarks PDFs (up to 60 MB, 200 pages). Convert other files to PDF first.
- Are my files uploaded?
- No — your PDF is watermarked entirely on your device. Only the optional AI background-removal step uses our server.
