How It Works Under the Hood
Why Watermarks Stay in the File
When you add a watermark with our tool, it is drawn into the PDF page content. That means it appears in every reader and is hard to remove without specialized editing—so it is useful for marking drafts, protecting copyright, or labeling confidential documents.
In practice: Your file is processed on your device. Watermark pdf and stamp pdf stay private. You control opacity and position so the document remains readable. You get a free tool with no sign-up and no extra watermarks from us.
How to Use Watermark PDF in 3 Simple Steps
1. Upload Your PDF
Open the Watermark PDF tool and add your file by dragging it in or clicking to browse. The PDF is read on your device only—we do not upload it. That keeps drafts and confidential documents private.
If your PDF is password-protected, you must unlock it first. Use our Unlock PDF tool, then open the unlocked file here to add the watermark.
2. Design Your Watermark
Choose Text and type your label (e.g. "DRAFT", "CONFIDENTIAL", "© 2025 Your Company") or Image and upload a logo. Adjust opacity (transparency) so the content underneath stays readable—often 30–50% works well. Set rotation and position (center, diagonal, or custom). The watermark will apply to every page when you generate the new PDF.
For page numbers instead of a repeating stamp, use our Page Numbers tool. For header/footer text (e.g. date, filename), use Header & Footer.
3. Apply and Download
Click to apply the watermark to all pages. The new PDF is built on your device; we do not store it. The watermark is embedded in the file—removing it later is difficult, which is why it helps protect drafts and copyright. Keep an unwatermarked original if you need to edit later.
To add a password after watermarking, use our Protect PDF tool. To lock forms and annotations (including watermarks) into the page, use Flatten PDF.
Who Is This Tool For?
Drafts & Proposals
Stamp "DRAFT" or "CONFIDENTIAL" on documents shared with clients before final approval.
Legal
Mark court bundles as "COPY" or "ORIGINAL" and add confidentiality notices.
Photography & Design
Place a copyright notice or logo on PDF portfolios to discourage misuse.
Internal Docs
Label internal-only or pre-release documents so recipients know the status.
Troubleshooting Common Issues
Watermark covers the text.
Lower the opacity (transparency) slider to around 30–50% so the content underneath stays readable.
Logo looks pixelated.
Use a high-resolution PNG or SVG for your logo. Small or low-res images will look blurry when scaled.
I cannot watermark; the file seems locked.
Password-protected PDFs must be unlocked first. Use our Unlock PDF tool, then add the watermark to the unlocked file.

Learn more →Can I remove the watermark later?
Watermarks are baked into the PDF, so they are hard to remove. Keep an unwatermarked original if you might need to edit later.
Learn more →What is the difference between watermark and page numbers?
Watermark adds custom text or a logo (e.g. DRAFT, logo) on every page. Page Numbers adds sequential numbers (1, 2, 3…) in the header or footer. Use Page Numbers for numbering; use Watermark for branding or labels.

✕ Using full opacity so the document is hard to read
Solution: Lower the watermark opacity (e.g. 30–50%) so the main content stays readable while the label is still visible.
Tip: Preview before downloading to check readability.
✕ Trying to watermark a protected PDF
Solution: Unlock the PDF first with our Unlock PDF tool, then add the watermark. You can re-protect with Protect PDF after.
Tip: Keep the original if you need to change the watermark later.
