Frequently asked questions

Is my PDF uploaded when I watermark it?
No. Watermarking runs entirely in your browser. Your file never leaves your device.
Can I use an image as a watermark?
Yes. Add optional PNG or JPG artwork in addition to (or instead of) text.
Can I preview before downloading?
Yes. A live preview of page 1 updates as you change text, color, opacity, and position.
Does watermarking modify my original file?
No. A new PDF is created when you download. Your original stays unchanged on disk.
