If you have a lot of digital pictures and would like to crop more than one at a time, JPEGCrops is the best freeware option for you. This program lets you maintain the aspect ratio, but still crop your photos to only leave the exact portion of the photo you want to keep.
With JPEGCrops, you can use the same settings to crop a large number of photos in a batch. Alternatively, you can go through each photo and customize the crop for each picture one by one. JPEGCrops comes with many preset print sizes for cropping as well as the ability to define a custom crop size.
Select your images or a folder of images
Then pick a preset (or custom) crop size and crop all or crop individually.
