Add Watermark — questions
Can I use my logo as the watermark?
Yes — switch the type to Image and pick a JPG or PNG. It is embedded at your chosen scale with the same opacity controls as text.
What do tiled vs centered mean?
Centered places one large mark in the middle of each page; tiled repeats a smaller mark across the whole page so it can't be cropped out.
How transparent is the watermark?
You choose: subtle (12%), medium (25%) or strong (45%) opacity. Subtle keeps content readable, strong is hard to ignore.
Is my original file changed?
No — the watermark is applied to a new copy. Your original PDF stays untouched on your device.
