JpegCrop

JpegCrop is a very simple program that allows us to cut (to run the crop) JPEG image without loss of quality.

If virtually all graphics programs allow you to cut at will Jpeg images, because very few can do so without any loss of quality, leaving intact the original quality.
As is well known, in fact, every time you edit a JPEG image and prompted a subsequent rescue with subsequent recompression: This goes to affect the image quality (which does not happen with non-lossy graphic formats, like BMP and PNG, for example).

So if we work on a JPEG image that has already been compressed to the maximum and that would not support a new recompression, or if you just want to take a portion of a JPEG image without losing in quality, here JpegCrop comes to our aid.

It's a very light program (just over 600kb), which requires no installation. Its use is very intuitive, so that any user can use it in a few seconds (because it's not that hard to cut and save a portion of the image...).
