This is a Free web Tool to Reduce the File Size For JPEG Images, Compress Image To 100kb For Free, When a digital file is compressed, the data bits are removed to reduce its size. The two types of compression are lossless compression, which reduces files without losing quality, and lossy compression, which decreases files without sacrificing quality. Due to the characteristics of JPEG files, only lossy compression is practical for this type of photography. You may, however, control how much compression the image receives to achieve a fair balance between file size and image quality. , .
