Stamp text or an image watermark over your PDF.
Stamp text or an image watermark over your PDF. Add watermark runs entirely in your web browser, so your file is processed on your own device and is never uploaded to MyPDFMate.
Answers to the questions people ask most about using Add watermark.
Open Add watermark on MyPDFMate, upload your PDF, type your text or upload a logo, adjust the opacity, angle and position, and click Add watermark. It's stamped on every page.
Yes. It's free with no sign-up, and MyPDFMate adds no watermark of its own.
Yes. Upload a PNG or JPG image. PNG with a transparent background looks best.
Type the word as your watermark text, set the angle to about 45° and the opacity to around 20–30% so the document stays readable.
In the center, tiled across the whole page, or in a corner. Tiled watermarks are the hardest to crop out.
Yes. Use the opacity setting, since lower opacity keeps the content underneath easy to read.
Use Add watermark in any browser, with no Acrobat Pro needed. Mac Preview has no watermark feature.
The watermark is drawn onto the page, so it can't be switched off in a viewer, but a determined person with a PDF editor could remove it. For stronger protection, add a password with Protect PDF too.
The watermark is drawn into the page content, not added as a removable layer. To make it impossible to edit out, convert the watermarked file with PDF to JPG and back with JPG to PDF, which flattens each page into an image (text is then no longer selectable).
The watermark is applied to every page. To watermark only some, extract those pages, watermark them, and recombine with Merge PDF.
No. The watermark is added in your browser, and your PDF is processed in your browser.
