Frequently asked questions

Can I use an image or HTML as a watermark?

No. For security, this tool only draws plain text — it doesn't accept HTML, JavaScript, or fonts loaded from an external URL.

Is it applied automatically without confirming?

No. The watermark is only applied to the PDF after you explicitly confirm the text and the options.
