Frequently asked questions
- Can I change how the watermark looks?
- Yes. Type any text, then adjust the opacity and font size with the sliders. The watermark is placed diagonally across the centre of every page.
- Does the watermark go on all pages?
- Yes. The text you enter is stamped onto every page of the PDF in one step.
- Is my PDF uploaded anywhere?
- No. The watermark is applied entirely in your browser — your document never leaves your device.
