How to Add a Watermark to a PDF — Step by Step
-
Drop your PDF
Drag any PDF onto the dropzone above, or click Select PDF to browse. The file loads into your browser memory only — there is no server upload.
-
Choose text or image watermark
Text watermarks are the default — type CONFIDENTIAL, DRAFT, INTERNAL, your name, or anything else. For image watermarks (company logo, signature, stamp) toggle to image mode and upload a JPG or PNG.
-
Pick layout + opacity + rotation
Three layout presets: single position (one watermark per page, anchored to a corner or center), diagonal (one large rotated stamp across the page), or repeating tile (the watermark repeated across the whole page in a grid). Adjust opacity 0-100%, rotation -90° to 90°.
-
Preview + apply + save
The modal shows a live preview as you adjust settings. Click Apply to bake the watermark into every page (or a specific page range), then Save to download the watermarked PDF. No upload, no watermark on the watermark.

For a watermark you'll add once and never think about, the cloud tools work fine. For repeated watermarking of contracts, drafts, or anything you wouldn't paste into a chat, local-only is the right answer.
Common Watermark Use Cases
CONFIDENTIAL stamp
Diagonal text at 45° across every page, 30% opacity, large size. The most common pattern for legal, HR, and financial documents that shouldn't leave the company.
DRAFT marker
Repeating tile pattern in light gray, low opacity. Communicates "not final" without obscuring the content for review.
Company logo
Image watermark, anchored to a corner, 60-80% opacity. Brands every page of contracts, proposals, and external deliverables without distracting from the content.
Author / copyright
Text watermark with your name + year, anchored bottom-center. Common for original work shared in PDF form (sheet music, photography portfolios, technical manuals).
SAMPLE / DEMO
Repeating tile pattern in red or orange, 40% opacity. For sample chapters, demo files, and "evaluation copy" distribution.
RECEIVED / APPROVED
Single-position stamp in a corner, full opacity. The digital equivalent of an office stamp for inbound document handling.

Is this watermark tool free?
Yes, 100% free forever. No trial, no premium tier, no per-file charge, no daily quota.
Is my PDF uploaded?
No. The watermark is added entirely in your browser. Adobe, iLovePDF, Sejda, Smallpdf, PDF24 all upload — we don't.
Can I add an image watermark?
Yes. JPG and PNG images are supported for image watermarks (logos, signatures, stamps).
Can I add a text watermark like CONFIDENTIAL or DRAFT?
Yes — text watermarks are the default. Type any text, choose font, size, color, opacity, rotation.
Can the watermark repeat across the page?
Yes — the layout option offers single-position, diagonal stamp, or repeating tile (text repeated across the whole page in a grid).
Will the watermark be on every page?
Yes by default. The modal also offers per-page-range options (e.g. pages 1-3 only).
Is the watermark permanent?
Yes — the watermark is baked into the PDF as real content-stream operators. Removing it requires PDF surgery.
Does the output have a watermark on the watermark?
No. iLovePDF and Smallpdf add their branding to some free-tier outputs; we never do.
Is there a file-size limit?
No artificial limit.
Does it work on mobile?
Yes — iPhone Safari, iPad, Android Chrome.
Does it work offline?
Yes once the page has loaded.
What is the best PDF watermark tool?
For privacy-first watermarking with no upload and no watermark-on-watermark, we believe pdfedit.com is the best free option. For desktop / batch work, Adobe Acrobat is the gold standard but costs $19.99/month.
