Frequently asked questions
Can I use a logo with a transparent background?
Yes. Choose a PNG or JPG up to 5 MB and 4 megapixels. PNG transparency is supported; the opacity control affects the whole watermark.
Which watermark text is supported?
One line of Latin text and common symbols, up to 80 characters. Use an image containing your text for Arabic or other scripts that the built-in font does not support.
Does a watermark protect my PDF from copying?
No. A watermark is a visible mark over the content. It is not encryption, a signature or access control, and it does not securely redact information.
Can I watermark only some pages?
Yes. Enter page numbers and ranges, such as 2-5,8, or leave the field blank for all pages. Every original page remains in the output.
