Watermark PDF

Why watermark a PDF?

A watermark marks a document as yours, or as not for circulation. Stamp "CONFIDENTIAL" across a contract, "DRAFT" on a proposal, "SAMPLE" on a portfolio, or your own logo across every page of a report you're about to send out. It's a clear visual signal of ownership or status that travels with the file wherever it goes. You can watermark with text or with your own logo. For text, type the words, choose from a large font library, then set the size, colour, opacity and angle, and either place it in one spot or tile it across the whole page. For a logo, upload a PNG or JPG and size it to taste. Either one can sit over the content or tuck below it, on every page or just a page range you specify. One honest note: a "below content" watermark can disappear behind scanned or solid-background pages, and a watermark drawn over a page is a visual mark rather than encryption, so a determined editor could remove it. Everything runs in your browser, so your PDF and your logo never leave your device.

How do I add a watermark to a PDF for free?

Pick Text to type words like CONFIDENTIAL, or Logo to upload a PNG or JPG, then set the opacity, angle and size, choose whether it sits over or below the content, and apply it to every page or a page range. It all happens in your browser, so the PDF and your logo are never uploaded.

Frequently asked questions

Can I use my own logo, or only text?
Both. Switch to Logo and upload a PNG or JPG to stamp your image across the pages, or use Text to type words like CONFIDENTIAL or DRAFT and style them however you want.
Can I control the opacity and angle?
Yes. Set the opacity anywhere from faint to solid (5% up to 100%) and rotate the watermark to any angle, including the classic 45-degree diagonal. You can also tile it so it repeats across the entire page.
Can I watermark only some pages?
Yes. Choose All pages, or pick Custom and enter a range such as 1-5, 8, 11-13 to mark just those pages.
Should the watermark go over the content or behind it?
Your call. "Over content" sits on top and stays visible everywhere. "Below content" tucks under the text for a subtler look, though on scanned or solid-colour pages a below-content watermark can end up completely hidden.
Is the watermark permanent and tamper-proof?
It's a visual watermark drawn onto the page, not encryption or DRM. Basic fonts stay as selectable text while decorative fonts and logos are placed as images, but in all cases it's a visible mark, so treat it as a deterrent rather than a lock.
Can I watermark several PDFs at once, and is anything uploaded?
You can add a batch and apply one watermark to all of them, or give each file its own. Nothing is uploaded: the PDF and your logo are processed entirely in your browser.
