PDF Watermark FAQ
How do I add a watermark to a PDF?
Upload your PDF, type the watermark text, adjust size, angle and opacity, then download the watermarked file.
Can the watermark be removed?
The watermark is drawn into the page content, so it can’t be simply toggled off. For maximum protection, combine it with Protect PDF.
Is it safe to use this tool with private PDF files?
Yes. Your PDF files are processed entirely in your web browser using JavaScript on your own device. Nothing is uploaded to FaaTools servers, so we never see, store or share your data — you can even disconnect from the internet after the page loads and the tool keeps working.
Is PDF Watermark free to use?
Yes, PDF Watermark is 100% free with no sign-up, no watermark and no daily limits. FaaTools is supported by unobtrusive ads, which keeps every tool free for everyone.
