Frequently asked questions
Can I change the watermark's position or size?
The watermark is placed diagonally across the center of each page at a size that scales with the page, giving consistent coverage without extra configuration.
Will the watermark make the original text hard to read?
The watermark uses a light, semi-transparent style so the original content stays readable underneath.
