different.  It recursively unpacks archives of many kinds and transforms
various binary formats into more human readable forms to compare them.  It can
compare two tarballs, ISO images, or PDFs just as easily.

remote diffoscope service}.

Diffoscope tries to get to the bottom of what makes files or directories
different.  It recursively unpacks archives of many kinds and transforms
various binary formats into more human readable forms to compare them.  It can
compare two tarballs, ISO images, or PDFs just as easily.

Results are displayed by default, stored as local text or html files, or made
available via a URL on @url{https://try.diffoscope.org}.  Results stored on the
server are purged after 30 days.")
