FAQ

Common questions

Can I add my company logo as a watermark?

Yes — use the image watermark option and upload your logo in PNG or JPG format.

Will the watermark be permanent?

Yes, the exported PDF has the watermark baked in. Keep your original if you need an unwatermarked copy.

Can recipients remove my watermark?

A burned-in watermark can't be removed without specialized software. For high-stakes documents, use our Redact tool on a copy first.

Is there a limit on watermark text length?

Text is capped at 120 characters to ensure it fits cleanly on the page.
