How do I add a watermark to a PDF?

Open pdfedit.com/watermark-pdf in any browser, drop your PDF, the watermark modal opens automatically. Pick text or image, set message + layout + opacity + rotation, click Apply. Save the watermarked PDF. No account, no upload, no watermark on the watermark.

How do I watermark a PDF?

Same answer — drop the PDF on this page, configure the watermark in the modal, click Apply, save. Works for text watermarks (CONFIDENTIAL, DRAFT, your name) and image watermarks (logo, signature, stamp).

How do I insert a watermark in PDF?

Drop the PDF on this converter — the watermark modal opens automatically with text and image options, layout presets (single position, diagonal stamp, repeating tile), and live preview.

Is this PDF watermark tool free?

Yes. 100% free forever — no trial, no premium tier, no per-file charge, no daily quota, no watermark on the watermark output.

Do I need an account?

No. No signup, no login, no email, no captcha, no credit card.

No. The watermark is added entirely in your browser using pdf-lib. Your PDF never touches our servers. Adobe, iLovePDF, Sejda, Smallpdf, and PDF24 all upload — we don't.

Can I add an image watermark (logo)?

Yes. The modal accepts JPG and PNG images for image watermarks — useful for logos, signatures, or visual stamps. Adjust opacity to make it subtle or bold depending on the use case.

Can I add a text watermark like CONFIDENTIAL or DRAFT?

Yes. Text watermarks are the default. Type any text, choose font, size, color, and rotation. CONFIDENTIAL diagonal across every page is the most common pattern; DRAFT and INTERNAL are also one-click presets.

Can I make the watermark repeat across the page like a tile?

Yes. The layout option offers single-position (one watermark per page), diagonal (one large rotated stamp), or repeating tile (text repeated across the whole page in a grid pattern, common for confidential / proof-of-concept docs).

Can I control opacity and rotation?

Yes. Opacity is 0-100% (default 30% for the subtle confidential look). Rotation is -90° to 90° in 1° increments — diagonal stamps usually use 45°.

Will the watermark show on every page?

Yes by default — the watermark applies to every page. 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 a real content-stream operator (text or image). Anyone opening the file sees it; it's not just metadata. Removing it requires PDF surgery and isn't trivial. For a watermark someone shouldn't remove, combine with PDF protection (set the 'editing' permission to off).

Is there a watermark on the output (a watermark on my watermark)?

No. The output PDF carries only your watermark, not ours. iLovePDF's free tier adds an iLovePDF watermark to some tool outputs; Smallpdf gates premium features. Ours is clean every time.

Is there a file-size limit?

No artificial limit. Memory is the only ceiling — modern laptops handle hundred-MB PDFs fine.

Does it work on mobile?

Yes. iPhone Safari, iPad, Android Chrome — any modern mobile browser.

Does it work offline?

Yes once the page has loaded. The PDF Edit engine is cached in your browser.

What is the best free PDF watermark tool?

For privacy-first watermarking with no upload, no signup, and no watermark-on-watermark, we believe pdfedit.com is the best free option. For desktop / batch automation, Adobe Acrobat is the gold standard but costs $19.99/month.
