littleJPG is a JPG optimizer / recompressor that can drastically reduce the file sizes of your JPG images with very little loss of quality. It is possible to reduce file sizes up to 98% in some cases with no visible degradation! Just drag your JPG files into littleJPG, and click one button to optimize and recompress the entire batch.
Note that littleJPG will re-encode your JPG images, so we recommend that you do not overwrite your original files. While the difference in quality is usually not visible (at least at the default settings), in the end littleJPG is utilizing lossy based encoding algorhithms.
