Frequently Asked Questions

Does adding a watermark change the PDF standard?

No. The output remains a standard PDF and can be opened in regular PDF readers without special software.

Can I remove the watermark from the PDF later?

The watermark is added to the PDF content. Treat it as a visible mark for drafts, reviews, or confidential documents.

Will the watermark appear on all pages?

Yes. The watermark is applied to every page of the document at the center, with your selected rotation, opacity, color, and font size.

Is my file kept private?

Yes. Watermarking runs in your browser. Your PDF is not uploaded to external servers.
