FAQ
Is there a file size limit?
No server-side limit since processing is local. The limit is your device's available memory, which handles most files easily.
Why is this free with no limits?
Since compression runs in your browser, there's no server cost for us. That's why we don't need to restrict file sizes or charge fees.
