FAQ

Can I add both text and image watermarks?

Yes. Switch between text and image watermark modes in the tool. Text watermarks support custom font size and rotation. Image watermarks support PNG, JPG, and WebP formats.

Can I apply the watermark to specific pages only?

Yes. After uploading, select which pages should receive the watermark using the page picker. You can apply to all pages or a custom selection.

How do I control the watermark transparency?

The opacity slider controls transparency from 0 (invisible) to 1 (fully opaque). Values between 0.15 and 0.35 produce subtle watermarks; 0.5 and above are more prominent.

Can I position the watermark anywhere on the page?

Yes. Choose from preset positions (center, top-left, top-right, bottom-left, bottom-right) and adjust the rotation angle. Custom rotation values are also supported.

Are watermarks permanent?

Yes. Watermarks are embedded into the PDF content and cannot be removed with standard PDF viewers. The watermarked file is a new output file; your original is not modified.
