wxPackJPG

The larger the resolution of a picture, the more disk space it takes up on your computer. Since mobile phones are fitted with incredibly powerful cameras, you might end up with low disk space and wondering why. In this regard, wxPackJPG comes with the necessary tools to help you compress pictures without affecting quality.

Simple interface quickly gets you up and running

It doesn’t take a lot of time to get the application installed on your computer, so you can check out the set of features before you realize. The main window is pretty intuitive, even though populated by simple elements and buttons. Compression and decompression tools are found in individual tabs so you don’t feel overwhelmed.
Needless to say that the application only accepts JPG pictures as input. Adding files can either be done through multiple selection using the browse dialog, or dropping files and folders over the window so the program automatically loads them. There’s also a preview area to show selected pictures.

Leaves much to be desired

Compressed files can end up in the same directory, with an option to overwrite existing files. On the other hand, you can choose a different destination, which is a good idea considering compressed files can’t be opened with the default viewer. Additionally, the application can verify processed files so no errors occur.
It’s rather disappointing that output files can’t be viewed with regular tools. What’s more, compression can only save up to 20% disk space, so you mostly benefit from compression when processing incredibly large collections. It can take some time to compress, as well as to decompress, process which is done in a similar manner.

A few last words

All things considered, we can state that wxPackJPG manages to get the job done as intended, but overall practicality might not really meet your demands. Compression delivers files in a different format, so preview requires decompression, while space is saved only when processing a considerable amount of files.
