Frequently Asked Questions

Are my PDF files uploaded to your servers?

No. This tool is built using next-generation client-side technologies. Your PDF is processed entirely inside your own web browser's memory. No files are ever uploaded, saved, or stored on our servers.

Can I use an image as a watermark instead of text?

Yes! You can switch to the 'Image Logo' tab in the designer and upload any PNG or JPG image. We even have a built-in toggle to automatically remove solid white backgrounds from logos.

How do I make a diagonal watermark across the page?

Simply use the 'Angle Rotation' slider in the designer panel. Setting it to 45° or -45° will create a perfect diagonal watermark. You can then use the font-size slider to make it span the entire page.

Can I apply the watermark to only specific pages?

Absolutely. Scroll down to the 'Page Distribution Selector' where you can choose to stamp only the first page, only the last page, or a custom range (e.g., '1-3, 5').
