✳ FREE CALCULATOR
Compression ratio calculator
Compare the original and compressed sizes to see the real saving, the ratio, and how much quality budget each remaining megabyte represents.
- Compression ratio
- 5.56:1
- Space saved
- 82.0%
- Size difference
- 205.0 MB
- Resulting bitrate
- 6,291 kbps
Calculated as: ratio = original ÷ compressed; saved % = (original − compressed) ÷ original × 100
What this assumes
- A high ratio is not automatically good - it only tells you about size, never about how the result looks.
- Re-compressing an already-compressed file often produces a poor ratio and visible damage together.
Koldflux works these numbers out for you when it exports - the calculators exist because our own pipeline needed them first.
