Frequently asked questions
Can I use my logo?
Yes: choose “Logo or image”. A PNG with a transparent background looks best.
Does it cover the document's text?
The mark is transparent: choose “Soft” if you want it to barely get in the way of reading.
Can it be removed later?
It's drawn on each page. Keep your original PDF without the mark in case you need it.
Is my PDF uploaded?
No. Everything is done on your device.
