Frequently asked questions

Which files compress best?

Text, CSV, logs, JSON and office documents often shrink 60-90%. JPGs, MP4s and ZIPs are already compressed and barely change.

Is there a size limit?

Only your device's memory - a few hundred MB is typically fine since everything runs locally.
