FAQ
Can I use an image watermark?+
Text only for now. For logo images, you'll need a PDF editor.
Does it support Korean?+
Yes. Korean watermarks like '대외비' (Confidential) work. They render using the system's default Korean font.
Can I watermark only certain pages?+
Currently all pages at once. To watermark a subset, [PDF page extract] those pages first, watermark them, and merge back.
Will it block copying or printing?+
Watermarks are visual only — they don't prevent copying or printing. For real protection, use PDF encryption or copy protection tools.
The watermark hides body text. How can I make it look better?+
Lower opacity to 30–50% and use a gray tone — that keeps body text readable. Diagonal placement (45°) also helps.
Can I remove the watermark later?+
It's flattened into the text layer, so removal is usually difficult. Keep the original safe separately.
