Frequently asked questions
- Is the PDF uploaded when adding a watermark?
- No. The watermark is embedded locally in your browser.
- Do Chinese watermarks work?
- Text watermarks in any language work — check the position and opacity in the preview.
- Does it stop screenshots?
- A watermark discourages reuse but cannot prevent screenshots; combine it with encryption for important files.
