Frequently asked questions
Can I add a text watermark with a custom font?›
Yes. Choose your text, font size, colour, opacity, and position (centre, diagonal, corners).
Can I use a logo or image as a watermark?›
Yes. Upload a JPG or PNG watermark image, then adjust its scale, opacity, rotation, and position.
Can I watermark only specific pages?›
Currently, watermarks are applied to all pages. Per-page control is coming in a future update.
Does the watermark prevent copying?›
Text watermarks are visible but not a security measure. For copy protection, use Protect PDF to encrypt the document.
Can I change the opacity of the watermark?›
Yes. Use the opacity slider to make the watermark more subtle or more visible.
Can I place the watermark in a corner?›
Yes. Choose any corner position or use the diagonal layout for a more prominent stamp.
Does the watermark work on mobile?›
Yes. The tool is responsive and works on modern mobile and desktop browsers.
