EPUB-Checker1.8.0

EPUB-Checker is a compact and portable application that allows you to check the validity of your ePUB files, namely their formal structure to compare it with the official ePUB specification.

Can even be run from a USB flash drive

The software utility comes packed with just a few settings that can be configured by anyone, even users with little or no experience in computer software.Since there is no setup pack involved, you can drop the executable file anywhere on the hard disk and just click it to run.It is also possible to save EPUB-Checker to a pen drive or similar device, in order to run it on any machine with minimum effort and no previous installers.What's more, the utility does not create new entries in the Windows registry or Start menu, leaving the disk clean after removal.

Analyze details and save log to file

The interface is represented by a regular window with a plain and simple structure, where you can point out an ePUB file for validation using the file browser only, since drag-and-drop is not supported.The simple click of a button is required to start validation. EPUB-Checker shows details in the main frame, including the ePUB version that the file is tested against, along with time and date.Furthermore, you can save the log to a plain text document for closer inspection or set EPUB-Checker to automatically save it on task completion, as well as change the UI language.

In conclusion

The application quickly verifies ePUB files and uses low-to-moderate CPU and RAM in the meantime. Other apps may become less responsive during this task. However, no error dialogs were shown in our tests, and the tool did not hang or crash. All in all, EPUB-Checker serves its purpose.
