JHOVE (pronounced “jove”), the JSTOR/Harvard Object Validation Environment, is an extensible software framework for performing format identification, validation, and characterisation of digital objects. The OPF have assumed active responsibility for the project and software creating a permanent, sustainable home for JHOVE.


We’re currently curating a copy of the original JHOVE website at http://jhove.openpreservation.org/ to ensure it is up to date and accurate. The site provides user and developer documentation.


You can download the installer for the latest version of JHOVE below:

Support JHOVE

JHOVE is open source: it is free to download, use and modify. However, it is not free of costs to host, maintain, support or develop the software. JHOVE is one of the most widely-used digital preservation tools, but currently only OPF members support JHOVE financially as part of their membership fees.
