Can I add images as watermarks?

Currently, we support text-based watermarking. Support for image-based watermarks (logos) is coming soon in a future update.

Does this affect the text in my PDF?

No, the watermark is added as a semi-transparent layer on top of your existing content, ensuring all original text remains readable.

Is the watermark permanent?

The watermark is embedded into the PDF structure of the new file we generate. You will always keep your original original document unchanged.
