How does audio compression work?

Audio compression reduces file size by encoding audio at a lower bitrate. Our compressor converts audio to MP3 at your chosen quality level, which can dramatically reduce file sizes from lossless formats like WAV or FLAC.

What quality settings should I use?

For music, 'High' (320kbps) preserves excellent quality. For voice recordings or podcasts, 'Medium' (192kbps) is ideal. 'Low' (128kbps) creates the smallest files and is fine for speech content.

Can I compress WAV files?

Yes. WAV files are uncompressed and benefit enormously from compression. Converting a WAV to MP3 at 192kbps typically reduces file size by 90% or more.

Will I notice quality loss?

At 192kbps or higher, most people cannot distinguish compressed audio from the original in normal listening conditions. Below 128kbps, some quality loss may become audible.

Is my audio file uploaded anywhere?

No. All compression happens in your browser. Your audio file stays on your device throughout the entire process.
