EpubCheck

EpubCheck is a handy command-line tool that helps you check your IDPF ePub files for any errors. It can find issues related to the OCF container structure, OPF and OPS markup, and even internal references. Basically, it's there to make sure your ePub files are in tip-top shape!

Easy Setup with EpubCheck

The best part? You don't need to go through a complicated setup process. If you've got Java installed on your computer, you can easily run EpubCheck from the Command Prompt. Just type a few lines and you're good to go!

Portable Use

You can even save EpubCheck onto a USB flash drive or any storage unit. This way, you can run it on any PC without a hassle as long as Java is installed there too.

No Traces Left Behind

One cool feature of EpubCheck is that it doesn't mess with your Windows Registry or Start menu. No new entries are created when you use it, so once you're done, it leaves no traces behind after removal.

How to Use EpubCheck

Using EpubCheck is super simple! Just point it to the path of an ePub file and hit a key to start checking for errors. It will quickly show any problems or warnings that pop up. There aren't many extra options here, but it gets the job done.

Reliability and Speed

In our tests, we didn't run into any issues—the application didn't freeze or crash at all! It responds quickly and runs scans fast while using very little CPU and RAM. So if you're looking for an easy-to-use tool for checking ePub files, EpubCheck is definitely worth considering!
