A watermark protects your document — both legally and visually. It signals ownership, marks drafts, flags confidentiality, or just adds a "do not copy" message that's hard to ignore.
The Watermark PDF tool stamps customisable text watermarks across every page. Here's the full walkthrough.
Step-by-step: how to use Watermark PDF
- Open the tool. Visit ilovepdf.cyou/watermark-pdf.
- Upload your PDF. Drag and drop the PDF you want to watermark.
- Enter watermark text. Type the text you want stamped, e.g.
CONFIDENTIALor your name. - Pick opacity & position. Choose opacity from 0.1–0.9 (lower is more transparent). Pick a position: centred (diagonal) or one of four corners.
- Process and download. The watermark is applied to every page. Save as
ILovePDF-watermark.pdf.

- Brand protection. Visible attribution makes unauthorised reuse obvious and harder to crop out.
- Draft & status flags. Stamp DRAFT, FINAL, REVIEWED or CONFIDENTIAL so the document's status is always clear.
- Customisable opacity. Subtle (0.2) for branding, bold (0.8) for high-visibility status flags.
- Five position presets. Centre diagonal, or any of the four corners — covers every common use case.
Common use cases
For Designers
Stamp portfolios with your name so clients can't crop you out and re-share.
For Legal & finance
Mark every page of a contract draft as DRAFT until the final version is locked.
For Education
Watermark exam papers as CONFIDENTIAL until they're officially released.
Pro tips for the best results
1. Lower opacity for branding
Use 0.2–0.3 opacity for subtle brand watermarks. Use 0.7+ for status messages.
2. Diagonal centred is the strongest
Centre position rotates the text 45°, the hardest layout to crop out.
3. Watermark before signing
Apply the watermark first, then run through Sign PDF for the final signature.
4. Combine with Protect PDF
For maximum security, watermark and then password-protect the PDF.
Frequently asked questions
Can I watermark with an image?
Currently text watermarks only. Image watermark support is on the roadmap.
Will the watermark obscure my content?
Lower opacity (0.2) keeps content readable. Higher opacity (0.8+) is for high-visibility flags.
Can different pages have different watermarks?
One watermark per run. Split the PDF first if pages need different stamps, then merge again.
Is the watermark removable?
Watermarks are permanently rendered into the PDF — they can't be programmatically removed.
