Frequently asked questions
Is compressing audio free?
Completely — no signup, no watermark, no limit. There is no server, so there is nothing to charge for.
Is my audio uploaded?
No. Compression runs entirely in your browser. Your audio never leaves your device.
Does compressing lose quality?
Yes — this re-encodes to MP3 at a lower bitrate, which is lossy. The file gets smaller but a little detail is lost. We tell you this plainly and let you pick the quality/size trade-off.
Which setting should I pick?
192 kbps keeps near-original quality with modest savings; 128 kbps is a good all-round balance; 96 and 64 kbps make the smallest files and suit voice notes and podcasts.
