How to validate my ePub file
You can validate your epub file online or locally by epubcheck or by ePub Maker.
Now there are several sites providing free validation service.
- You can upload the official IDPF site to validate it.
- We also has a validation site on ePuubValidator.com. The validation is only under ePub 2.0 standard.
How to setup ePubCheck
If you want to validate your ePubs on your own computer, you need to install ePubcheck first. Then set it up in ePub Maker.
