Add text or image watermarks to every page of your PDF. DRAFT, CONFIDENTIAL, your logo — whatever you need.
Need to mark a PDF as a draft, confidential, or brand it with your logo? Adding a watermark is the professional way to do it.
Adding a watermark to a PDF sounds like it should be a basic feature. But in most PDF editors, it is either hidden so deep you cannot find it, or it is a pro-only feature behind a subscription paywall. Adobe Acrobat Pro does watermarks, yes — for 15 dollars a month. With an online watermark tool, you do it for free. Drop the file, set up your watermark, download. Done. With PDFNeo, it all happens locally in your browser too. Your document never gets uploaded to a server. That is important for watermarking because you are usually marking documents precisely because they contain sensitive or proprietary information. The last thing you want is to send that to some random company's cloud. And it works on any device with a browser.
Marking documents as DRAFT or CONFIDENTIAL. You are sharing a document internally and you want to make it clear it is a draft, not final. Or it contains sensitive information that should not be shared further. A big diagonal watermark gets the message across.
Branding documents with your logo. You are sending out proposals, reports, or invoices and you want your company logo subtly visible on every page. It looks professional and reinforces your brand.
Protecting content from unauthorized sharing. You are sharing proprietary information and you want to deter people from passing it off as their own. A watermark with a name or company makes it clear where the document came from.
Adding status labels to shared documents. FOR REVIEW ONLY, APPROVED, DO NOT DISTRIBUTE — different stages of a document need different labels. Watermarks make the status instantly visible to anyone who opens it.
Use the right opacity for your use case. For a draft or confidential watermark, go higher (0.5 to 0.7) so it is clearly visible. For branding that should not distract from the content, go lower (0.1 to 0.2) for a subtle effect.
Diagonal watermarks are harder to remove. If you are watermarking to protect content, a diagonal watermark across the whole page is harder to crop or edit out than one tucked in the corner. Think about placement based on why you are watermarking.
Text watermarks work great for status labels. CONFIDENTIAL, DRAFT, DO NOT DISTRIBUTE — text watermarks are perfect for these. Use a bold font and make it big enough to read at a glance but not so big it blocks the content.
Test one page first if you can. Before watermarking a 100-page document, test on a single page to make sure the size, opacity, and placement look right. It saves you from doing the whole thing twice.
Yes — you can use either text or an image file as a watermark. Upload your logo, signature, or custom watermark graphic and place it on the pages.
Absolutely. The opacity slider lets you control how visible the watermark is. Make it bold and obvious or faint and subtle — whatever works for your use case.
Nope. Everything runs locally in your browser. Your document and your watermark image never leave your device. Close the tab and everything is gone from memory.
Yes — the watermark is applied to all pages of the PDF. If you only want it on certain pages, extract those pages first, add the watermark, then merge everything back together.
This tool adds watermarks. Removing an existing watermark is much harder — once it is baked into the PDF pages, it is part of the content. Some editing tools can help, but results vary.
It depends on why you are watermarking. For status labels like CONFIDENTIAL, large and diagonal is standard. For branding logos, smaller and in a corner is more appropriate.
100 percent free. No sign up, no watermarks on the tool itself, no page limits. Just a watermarking tool that works in your browser.
