Calculate the compression ratio, space saved and size reduction from original and compressed file sizes, free online.
À propos de cette calculatrice
Compression ratio = original size ÷ compressed size (a ratio of 4:1 means the file is a quarter of its size). Space saved = 1 − compressed ÷ original. Also shown: the bitrate saving and the time to transfer each version.
