Frequently asked questions

How do I put my company logo on every page?

Choose "Image (logo)", upload a PNG with a transparent background, pick a corner position and select "All pages".

What's the difference between a stamp and a watermark?

A stamp is a single overlay placed at an exact spot (like a logo or "APPROVED" mark), while the Watermark tool repeats text across the whole page.

Are my PDF and logo uploaded anywhere?

No — the overlay is drawn in your browser; neither the PDF nor the image leaves your device.
