How it works

1. Upload your file

Drag and drop or choose a PDF file from your device. Everything is checked against its real file type before processing starts.

2. We process it

Your file runs through an isolated job dedicated to Add Watermark, with clear progress so you always know what stage it's at.

3. Download the result

Get your finished PDF file with one click. The original upload and the result are deleted automatically afterward.

What is Add Watermark?

Add Watermark stamps text across the pages of a PDF, such as "CONFIDENTIAL" or "DRAFT". You control the position, rotation, opacity, colour and whether it sits over or under the page content.

Common uses

Marking drafts. Label a document DRAFT so nobody mistakes it for the final.
Confidential documents. Stamp CONFIDENTIAL across every page before sharing.
Ownership notices. Add your company or name so copies are traceable.
Proofs and samples. Show a sample document with a visible mark.

Watermark options
Text	Up to 80 characters
Opacity	5% to 100%, default 25%
Rotation	0, 45, 90, 180 or 270 degrees
Position	Nine places, or tiled across the page
Layer	Over the content, or under it
Pages	All pages, or a range
Sign-up	Not required

Tips for best results

Keep opacity low (20-30%) so the page stays readable.
Use the tiled option for a hard-to-crop mark.
Place it under the content if you do not want it to hide text.
Image watermarks are not supported; text only.

Your file stays private

Add Watermark runs in an isolated processing job. Your upload and the generated result are deleted automatically after your download window ends — we don't keep copies, and download links are random, single-purpose, and expire.

Frequently asked questions

How do I add a watermark to a PDF?

Upload the PDF to Add Watermark, type your text, set position and opacity, and download the stamped PDF.

Can I use an image or logo?

Not currently. This tool supports text watermarks.

Can I watermark only some pages?

Yes. Choose a from-page and to-page.

Can the watermark be removed afterwards?

It is drawn onto the page, so it is not meant to be toggled off. Keep your original unwatermarked file.

Is it free?

Yes, free with no sign-up.

Do I need to sign up to use Add Watermark?

No — this tool works without creating an account. There is no sign-up option at all right now.

What file types does Add Watermark accept?

Add Watermark accepts PDF files and produces a PDF result, up to 1 file per job.

Will my formatting or content be preserved?

Only the specific change you make is applied — everything else on the page stays exactly as it was in your original file.

What happens to my file afterward?

Your file is processed in an isolated job and deleted automatically, along with the result, once your download window ends.
