Original Size (MB)

Compressed Size (MB)

A data compression ratio calculator determines how much storage space is saved by compression, and estimates compression/decompression time. Compression ratio = original size ÷ compressed size. Text files typically compress 3–10×; already-compressed files (JPEG, MP4) see minimal benefit.
