Frequently Asked Questions
What is PDF stamping and how does it work?
PDF stamping automatically adds the buyer's name and email to each page of downloaded PDF files, discouraging unauthorized sharing by making each copy uniquely identifiable.
How are files delivered to customers?
After purchase, customers automatically receive an email with a secure download link. The link can be configured to expire after a set number of downloads or a specific time period.
Is there a file size limit for uploads?
File size limits depend on your plan. The free plan includes 1 GB of total storage, while paid plans offer significantly more. Individual file size limits are generous enough for most digital products.
