Jhead

Jhead is a simple command-line application that allows you to view and edit EXIF information found in images with the JPEG format. It comes packed with a wide range of options for all user levels.

What command-line tools lack in the visual aspect (since there is no graphical console available), they usually make up in flexibility toward manipulating data. This is because most of the issues while programming complex visual interactions does not exist here.

After launching a command-line dialog, you can check out a list of all options made available through Jhead. For example, you can transfer the EXIF header from one image file to another, or delete comment fields.

It is also possible to delete the IPTC and XMP sections, strip all unnecessary data from the JPEG item in order to reduce its size, create a new minimal EXIF section, as well as save the comment section to a file.

You can set the file modification time to the EXIF time or vice versa, rename files according to the date, fix date and time offsets of multiple pictures at the same time, as well as replace the thumbnails inside EXIF headers, to name but a few of Jhead's options.

The tool does not burden the computer's overall performance, since it uses a very low quantity of CPU and system memory. It works well, without making the operating system hang, crash or pop up error dialogs. Jhead offers users many possibilities when it comes to modifying EXIF information of JPEGs.

All things considered, we can state that Jhead is a little tool with which you can accomplish a lot. Even if it’s not wrapped around a pretty interface, it’s packed with a heavy deal of functionality to meet most of your EXIF editing demands.
