Q: I created some layers in a PDF document that I no longer need, how can I delete these layers in PDF Studio?
A: As of version 2019, PDF Studio is not able to delete existing layers in a PDF, though this feature will soon be implemented and added to a future version.
For now, as a workaround, you can follow the steps below. The process consists in creating a new PDF and appending your layered PDF. This process will remove any layers present in the document.
