Frequently Asked Questions
Can I customize the watermark text, color and opacity?
Yes — set your own text, pick a color, adjust the opacity and set the font size before applying it.
Does the watermark repeat across the page or appear once?
It’s stamped once per page, centered, at a 45-degree angle — not tiled repeatedly across the page.
Will the watermark appear on every page of my document?
Yes — the same watermark is applied to every page in the PDF; there’s no option to skip specific pages.
Can I use my own logo image as a PDF watermark instead of text?
Not on this tool — it’s text-only. For a logo watermark, use the Logo/Image Watermark tool on images before converting them to PDF.
Can I watermark multiple PDFs at once?
No — this tool processes one file per request.
