JPEG compression tool that can help you batch reduce the size of your image files and optimize your photo library without compromising on quality
Photo collections can take up a lot of space while sharing images at their full size require more bandwidth and time to load. JPEG Jackal is an easy to use OS X utility that can help you batch optimize your JPG files.
Scan entire folders for JPEG images that can be compressed to save space
To start using the JPEG Jackal application, you must simply drag and drop the picture files you want to process on top of the app’s main window. Note that the utility can only handle the JPEG file format.
Worth mentioning is that you can also drop entire folders on the JPEG Jackal main window and the app will start scanning them for files that can be optimized. Via the JPEG Jackal Preferences you can also choose to have the subfolders analyzed.
The same JPEG Jackal Preferences panel allows you to adjust the compression level, going from high compression to high quality: just move the marker along the slider bar to change the configuration.
Experiment with the built-in compression algorithm without altering the originals
Since JPEG Jackal allows you to output the optimized file to a separate folder, you can experiment with the configuration until you get a satisfactory result. The app can prompt you for the output directory each time you launch a compression task.
On the other hand, JPEG Jackal allows you to change the default settings either to overwrite the files or to automatically save them to the selected folder.
Once the process is done, in the JPEG Jackal main window you get to see how much space has been freed up. The app expresses the information in percentages, but also generates a graph to help you visualize the information.
Reduce the size of your photos collection without losing out on quality
To sum up, JPEG Jackal comes with a built-in JPEG optimization algorithm that enables you to decide if you want to increase the compression level and reduce the files’ size, or you want to preserve the quality.
