FAQ
What buyers usually ask first.
What does the commercial license actually cover?
The commercial license is intended for teams using ZingPDF in paid products, internal business systems, or client-delivered software where a proprietary licensing path is required.
What if my company needs procurement, invoicing, or custom terms?
That is what the Enterprise option is for. It gives you a direct path for larger seat counts, redistribution rights, and support expectations.
How mature is the library today?
ZingPDF already covers practical workflows like page editing, forms, metadata, encryption, watermarking, compression, and incremental save behavior, with ongoing work to keep the product release-ready.
Can I evaluate the library before committing to a larger purchase?
Yes. ZingPDF is fully functional prior to purchase. See the developer docs to get started with the API and current capabilities.
