Frequently Asked Questions
Can I add an image watermark to my PDF?
Currently, only text-based watermarks are supported. You can customize the text content, font size, color, opacity, rotation, and position to create the exact look you need. Image watermark support is planned for a future update.
Can I adjust the opacity and rotation of the watermark?
Yes. Opacity can be set from fully transparent to fully opaque, and the rotation angle is fully customizable. A diagonal watermark at around 45 degrees with medium opacity is a popular choice for document marking.
Where can I position the watermark on the page?
Five positions are available: center (most common for diagonal watermarks), top-left, top-right, bottom-left, and bottom-right. The watermark is applied consistently to every page of the document.
