A "DRAFT" stamp, a company logo, a confidentiality notice -- watermarking a PDF is one of the most common document-prep tasks there is. Add Watermark applies it across every page in one pass, free.
How to add a watermark
- Open Add Watermark and upload your PDF.
- Choose text (like "DRAFT" or "CONFIDENTIAL") or upload a logo image.
- Adjust position, size, rotation, and opacity to taste.
- Apply and download the watermarked PDF.
Getting a watermark that works
- Lower the opacity for a watermark that doesn't interfere with reading the underlying text.
- Diagonal placement across the page is harder to crop out than a corner stamp, if the watermark is meant to deter copying.
- Use a logo for branded handouts, plain text for internal status markers like "DRAFT" or "INTERNAL ONLY."
Frequently asked questions
Can I use my own logo as the watermark?
Yes -- upload an image and it's applied the same way a text watermark would be.
Can I control how visible the watermark is?
Yes -- adjust the opacity so it's subtle or bold, depending on the purpose.
Does the watermark apply to every page?
Yes, by default -- it's stamped consistently across the whole document.
Can I remove a watermark later if I need to?
If you added it yourself and kept the original file, yes -- for watermarks added by someone else, see Remove Watermark.
Mark it once, apply it everywhere -- try Add Watermark.
