Frequently Asked Questions
Is the watermark removable?
The watermark is drawn as a text layer. Determined users with professional PDF editors may be able to remove it. For tamper-proof watermarks, use Pro.
Can I use an image as a watermark?
Text watermarks are supported in the current version. Image watermarks (logo files) are coming in the Pro plan.
Will the watermark cover my content?
Use low opacity (15–30%) for a subtle watermark that does not obscure content. Higher opacity makes it more visible.
Does it work on all pages?
Yes — the watermark is applied to every single page of the document automatically.
