What this tool does
This page stamps a watermark over your PDF pages: a word like CONFIDENTIAL or DRAFT, or your logo as an image. You control the size, color, transparency, angle and position, and the live preview shows page 1 with your settings as you move them, so the stamp holds no surprises. Tiled mode covers the whole page with repeating stamps instead of one centered mark.
Text stamp or logo: pick what fits
Text stamps say things: CONFIDENTIAL for internal papers, DRAFT for versions, a company or website name for anything that leaves your hands. Image stamps show things: your logo, a signature graphic, a rubber-stamp drawing. A text stamp with your web address is the classic choice for documents you share publicly, a logo stamp brands portfolios and proposals.
Your files never leave your device
The big watermark tools upload your document and your stamp text to their servers, so a file marked CONFIDENTIAL travels across the internet to be stamped. Here everything happens in your browser: the PDF is read from your computer, stamped there, and saved straight back to your downloads. Turn off your WiFi after the page loads and the whole flow still works.
A watermark is a stamp, not a lock
Honest truth: anyone with a PDF editor can remove or cover a watermark, so a stamp expresses ownership and intent, it does not enforce them. Tiled stamps are harder to brush away than one centered mark. If the file must actually stay private, add a password on Protect PDF as well, one tool stamps, the other locks.
Need a different result?
Signing a form instead of stamping it? Sign PDF places your signature where it belongs. Need the stamped file to stay private? Protect PDF adds an AES-256 password. File too big to send after stamping? Compress PDF shrinks it.
Frequently asked questions
How do I add a watermark to a PDF for free?
Drop the PDF on this page, type your stamp text or pick a logo image, adjust the size and position while watching the live preview, then click Add Watermark. The stamped PDF downloads straight away. It is free, with no account, no watermark-of-the-watermark and no daily task limit.
Can I use my company logo as the watermark?
Yes, switch to Image stamp and choose a PNG or JPG. PNG keeps its transparency, so a logo with a clear background stamps cleanly over text. Set the width as a percentage of the page and lower the opacity until the document underneath stays readable, or turn on tiling to repeat the logo across the whole page.
Does this tool work if I turn off my WiFi?
Yes. Turn off your WiFi, this tool will still run 100% locally. Once the page has loaded, the preview and the stamping both happen on your own computer, and the watermarked file is saved straight to your downloads.
Can a watermark be removed from a PDF?
By a determined person with a PDF editor, yes, and any tool that claims otherwise is selling luck. A stamp marks ownership and intent. Tiled stamps are harder to remove cleanly than a single centered one, and an AES-256 password on Protect PDF protects the contents far better than any stamp can.
Which pages get the watermark?
Every page by default. Type a range like 1-3, 5 to stamp only those pages, handy for marking a cover sheet, the first page of a contract, or everything except an already-stamped appendix. The preview always shows page 1, so pick ranges that include it to see what you are getting.
