JPEG Optimizer Pro

Not all pictures you take are saved at maximum quality, and this can mostly be done because images at maximum quality take up considerable more disk space. However, to quickly fix this issue, specialized applications like JPEG Optimizer Pro allow you to enhance quality, and change resolution for more pictures at a time.

Lightweight, and easy to use

With only a little time spent installing the application, you get to check out the set of features before you realize. There’s one thing to consider though, and that’s whether or not .NET Framework is installed on your computer for JPEG Optimizer Pro to work, although modern Windows iterations come with it as a default feature.
The initial window gives you the possibility to optimize a single picture, or an entire collection in a custom folder. Regardless of your choice, you’re only able to work with JPG files, just like the name clearly points out.

Adjust quality, and size of JPG pictures

Once you load a picture, or a whole folder, with or without associated subfolders, a new menu shows up, with a large preview of the first picture. Size specifications are shown, so you get an idea of how much bigger, or smaller the new file is. In addition, you can set a maximum size limit by simply writing down values for width, and height.
Unfortunately, the only optimization you can perform is adjusting the general JPG quality slider. This isn’t necessarily a bad thing, especially since most JPG files get created at 90 percent quality. However, it would have been useful to see at least basic color manipulation sliders, or several quick presets.
It doesn’t take a lot of time for the application to process your entire collection. Don’t worry about the original files, because they’re not replaced, unless you enable this to happen. The alternative is to save them to a new folder, which is automatically created in the source directory.

To sum it up

In conclusion, JPEG Optimizer Pro comes with good intentions, and can get the job done as expected, helping you reduce, or increase the quality of JPG pictures, and even modify size. However, it could have used a bit more customization options, or at least a few style presets.
