Frequently asked questions
Can I watermark only specific pages?
Yes. Set the "From Page" and "To Page" fields to target a specific range of pages within your document.
What is mosaic mode?
Mosaic mode repeats the watermark in a tiled pattern across the entire page, making it difficult to crop or remove.
Can I use my company logo as a watermark?
Yes. Switch to image mode and upload your logo. You can adjust its opacity and position to suit your branding needs.
Will the watermark reduce PDF quality?
No. Watermarks are added as overlay elements without recompressing the existing content.
