Frequently Asked Questions
Can I customize the watermark appearance?
Yes. You can configure the watermark text, font size (12–120pt), rotation angle (-90° to 90°), opacity (5–100%), and color using a color picker.
Is the watermark applied to every page?
Yes. The watermark text is added to every page of the PDF at the center position with your chosen settings.
Can the watermark be removed later?
The watermark is embedded directly into the PDF content. It cannot be easily removed with standard PDF viewers, making it suitable for document protection.
Does watermarking change the file size?
The file size increase is minimal — typically just a few kilobytes — since the watermark is vector text, not an image.
