Frequently Asked Questions
Can I use a custom image logo as a watermark?
Yes. Upload a transparent PNG or JPG logo, scale it to your desired size, adjust its opacity, and position it precisely on the page with rotation control.
Can I change the transparency of the watermark?
Yes. An opacity slider lets you make the watermark faint enough to read through or bold enough to stand out, with a live preview as you adjust.
Can I apply watermarks to only specific pages?
Yes. Apply the watermark across all pages, or exclude specific pages like the cover sheet, directly from the page selection controls.
Can watermarks be removed after applying?
Once exported, the watermark becomes part of the PDF pages. Keep your original file if you may need an unmarked version later.
