Frequently asked questions
- Are my files uploaded to a server?
- No. Everything happens entirely on your own device, inside your browser. Your PDFs and any passwords never leave your computer, so there are no upload waits and no copies kept anywhere.
- How do I add a watermark to a PDF?
- Type the text you want, set the size, angle, colour and opacity, then download. The watermark is drawn across every page of the file.
- Can I make the watermark faint?
- Yes. The opacity slider goes from a barely-there tint to a bold stamp, so you can keep the page readable underneath.
- Can the watermark be removed later?
- The text is merged into each page, so it is not a layer that toggles on and off. Keep your original file if you may need a clean copy.
