Frequently Asked Questions
Can I remove the watermark later?
Our tool applies a permanent layer to your PDF. While some advanced PDF editors might be able to remove it, it serves as a strong deterrent for most users.
Does it support transparent logos?
Yes. If you upload a PNG with transparency, it will be rendered perfectly on top of your PDF content.
