FAQ
What does compression ratio mean?
It shows how many times smaller the compressed file is compared to the original.
Is a higher ratio better?
Yes, a higher ratio indicates more compression.
Can the compressed size be larger?
Yes, then the ratio will be less than 1.
Do units need to match?
Yes, use the same units for original and compressed sizes.
Additional Information
- A ratio of 5 means the compressed file is one-fifth the size of the original.
- Lossless methods preserve all data while lossy compression sacrifices quality for smaller size.
- Percentage reduction can be computed as (1 - 1 / ratio) * 100.
