Explanation:
Detailed explanation-1: -File compression reduces the size of the file as much as 90%, without losing any of the primary data. Compressing a file is also known as zipping. Therefore, file compression helps the user save a considerable amount of disk space.
Detailed explanation-2: -I compressed my video file, but after upload/conversion the file is actually a little bigger. Why? The quality and file size of a video are directly related to bitrate. To make the file size smaller, you reduce the bitrate of the video (compression), but you also begin to lose quality.
