How it works
How to add a watermark to a PDF
Upload your PDF, add text such as CONFIDENTIAL or DRAFT, or upload a logo. Choose the placement and opacity, then download the watermarked PDF. No account is required, and everything runs in your browser.
Upload your PDF
Choose the file you want to mark. It stays in your browser and is not sent to SignPaperless.
Add text or a logo
Type something like CONFIDENTIAL or DRAFT, or upload a PNG, JPG, or WEBP logo. Adjust size, opacity, and rotation.
Pick placement and pages
Use center, a corner, or a diagonal tile. Apply to all pages, the current page, or a page range.

Save the watermarked file to your device. Original page text stays selectable.

Good to know
Watermarking a PDF vs eSignature
A watermark is a visual label on a file you already have. It is not encryption and it does not collect signatures. SignPaperless is for sending documents, collecting signatures from other people, and keeping a record.
| Need | Watermark on this page | eSignature platform |
|---|---|---|
| Put a visual mark on a PDF you already have | Yes | Yes (as part of a workflow) |
| Free to use, no account | Yes | Requires an account |
| Prevent copying or editing the file | No | Not by itself; needs access controls |
| Send for others to sign with a record | No | Yes |
If you only need a visual mark on a PDF, stay here. If you need others to sign and keep a record, see what SignPaperless includes.
FAQs
Add Watermark to PDF FAQs
Common questions about privacy, logos, placement, and what a watermark does (and does not) do.
A PDF watermark is visible text or an image placed over one or more pages. It can label a file as DRAFT or CONFIDENTIAL, identify its owner, or show a logo, but it does not encrypt the PDF.
Yes. Upload a PDF, add custom text or a logo, choose where it appears, and download the watermarked file without creating an account.
No. The PDF is processed in your browser. It is not sent to SignPaperless when you use this page.
The PDF must be under 20 MB. If you use a logo, the PNG, JPG, or WEBP image must be under 5 MB.
No. It creates a separate watermarked PDF for you to download. The original file on your device is not overwritten.
Yes. Switch to Logo, upload a PNG, JPG, or WEBP image, then set size, opacity, and placement the same way as text.
No. A watermark is a visual mark. It does not encrypt the file or stop someone from editing or removing it. Use it for labeling drafts and shares, not as security.
Yes. Choose all pages, only the page you are previewing, or a from-to page range. Download once the preview looks right.
Yes. We draw the watermark onto the existing PDF. The document is not flattened into page images.
Encrypted PDFs often cannot be edited in the browser without the password. Unlock or export an unprotected copy first, then try again.
