Why Add a Watermark to a PDF?
- Copyright protection — Prevent unauthorized copying or distribution

- Client work — Watermark proofs sent to clients before final payment

Can I Remove a Watermark After Adding It?
Once a watermark is burned into a PDF, it becomes part of the document. Always keep a copy of the original unwatermarked PDF before applying a watermark.
Can I Add Multiple Watermarks?
Yes — you can apply one watermark at a time. For multiple watermarks, apply one, download, then re-upload and add another.
What Types of Watermarks Can I Add?
- Text watermarks — Any text, custom font size, opacity, and angle
- Diagonal watermarks — Standard 45-degree angle across each page
- Page-wide watermarks — Full page coverage for maximum protection
