Choose the mark that fits your document.

Before You Watermark
Know what a watermark cannot do
- Not encryption. A stamp does not restrict opening or copying.
- Not redaction. Underlying content may remain readable or selectable.
- Restricted PDFs. Encrypted or damaged files may fail to process.
- Digital signatures. Changing a signed PDF may invalidate its signature.
- Original files. Keep a clean copy for future changes.
Troubleshooting
| Problem | Likely cause | What to try |
|---|---|---|
| Stamp covers text | The stamp is too large or opaque. | Reduce the size or opacity. |
| Stamp is missing | The selected pages or layer may hide it. | Check the page selection and choose “Over the content.” |
| Logo looks blurry | The source image has a low resolution. | Use a clearer source image. |
| Processing fails | The PDF may be restricted or damaged. | Try a working, unrestricted copy. |
