    Frequently asked questions

    Can I use my own logo instead of text?

    This tool currently supports text watermarks only. Image/logo watermarking is on the roadmap — see the project README for how to extend it.

    Can the watermark be removed later?

    It becomes part of the page content, like any other stamped text — it isn't a removable "layer" in most PDF viewers.

    Does the watermark appear on every page, including blank ones?

    Yes, it's applied uniformly across every page in the document.
