Calculate Data Compression

Calculate data compression rate or data size before and after compression. Enter two of the three values at size and ratio and click Calculate.

Example: a file with 123 MB is compressed with a ratio of 1.5. The compressed file has a size of 82 MB, 33⅓ % space are saved. Space savings are given in percent. Umcompressed (before compression) and compressed (after compression) size must have the same unit, e.g. megabyte.
