A watermark tells readers at a glance what a document is: a DRAFT that shouldn't be quoted, a CONFIDENTIAL file that shouldn't be forwarded, a SAMPLE of a paid report, or a proof that belongs to your studio. You can use text or an image such as your logo, and adjust opacity, rotation and position so it's visible without making the page hard to read.
Watermarks are added in your browser and your PDF is never uploaded.
A watermark is a deterrent and a label, not a lock. A determined person with editing software can often remove it. For sensitive material, combine it with Protect PDF, or flatten the document so the watermark is part of the page.

Good to know
- Watermarks can be removed by someone with PDF editing tools; they are not a security control.
- Very opaque watermarks can make scanned or dense pages harder to read.
Frequently asked questions
Can I use my logo as a watermark?
Yes. Upload a PNG or JPG. A PNG with a transparent background usually looks best.
Can a watermark be removed?
It's harder for casual readers, but someone with editing software may remove it. Use it as a label or deterrent, and use Protect PDF for access control.
What opacity should I use?
Something around 20–40% is usually visible without hiding the text underneath. Preview and adjust to suit your document.
Is my document uploaded?
No. The watermark is added in your browser; the PDF never leaves your device.
