Frequently Asked Questions
Can I change the watermark color or size?
Currently it's a semi-transparent gray watermark at a medium size that fits most documents. More customization is coming soon.
Does the watermark appear on every page?
Yes, it's placed diagonally across the center of every page in the file.
Can I use Arabic text as a watermark?
Not yet. The standard PDF fonts we draw with cover Latin letters, numbers and punctuation only, so the tool will tell you which characters it cannot use rather than failing silently. Adding Arabic properly needs font embedding plus real letter shaping, and we would rather build that well than ship something that renders your text backwards.
