How to add a watermark to a PDF
Add a watermark puts your own words across every page. Type up to 80 characters, like DRAFT or CONFIDENTIAL, in the "Watermark text" box. Extra spaces at the start and end are removed. The words appear once in the middle of each page, tilted, in light gray and faint, so the page underneath stays easy to read. The size grows with the page. The watermark is text, not a picture, so you can't add a logo here. It does not lower the quality of your images, and it does not remove a watermark that is already there. The text on your pages stays selectable. You get one file named watermarked.pdf, and your original is not changed. We never add our own name or mark. Want a ready-made word? Try the DRAFT or CONFIDENTIAL stamps.
Your PDF stays on your device. It's never uploaded, and you don't need to share an email address. Your browser makes the new file and saves it as watermarked.pdf. When you close the page, nothing is left behind. Your watermark words stay on your device too.
Add a watermark is free. There's no account, no page limit, and no watermark. Very large files depend on your device's memory, so a huge PDF may not open.
If the text box is empty, you'll be asked to type a word or short phrase. If your text is longer than 80 characters, shorten it and try again. If your PDF won't open, it may be damaged or may not be a real PDF. Try another copy. Password-protected? It won't open here. Unlock it first with Unlock PDF, then try again.
