I. What does JPEG Compressor do?

JPEG file format is a based on lossy algorithm. Depending on the quality level you desire, you can reduce the size of the original JPEG files to lower quality ones. Since it reduces the sizes, it will save the disk space and speed up the load/display time.

The JPEG files you downloaded from Internet vary in size and qualities. Some of them are too big and the quality can be reduced without even be noticeable. Yamabay's JPEG Compressor can batch process them into smaller size JPEG files at the qality scale you specify. You can also reduce the size of the JPEG files interactively.

You can hightlight any of the file name and click on the button View Umage to view it. The Convert button will convert/compress the files checked, to the JPEG File Quality specified. The Quality level can be from 1 to 100, and the default is 80 .

Under Options menu item, there are: Convert, Remove, Check and View Image. Convert and View Image have been mentioned. Remove means remove from the screen, it does not actually delete the image, and Check means check or uncheck the image for later convert/compress process.
