Pick a quality, see the savings
Skip the kbps math. Choose Basic, Good, High, or Best and we handle the rest. We even check your file's source bitrate first and grey out presets that would make it bigger instead of smaller.
- Plain-language presets — no audio engineering required
- Source bitrate detected in your browser before you compress
- Before / after size bar shows exactly how much you saved
- Output to MP3, M4A, AAC, OGG, or Opus
How it works
Three steps, usually under 10 seconds start to finish.
Drop your audio file
Upload MP3, WAV, M4A, FLAC, AAC, OGG, OPUS, AIFF or WMA, up to 200 MB.
Pick a quality preset
Basic is fine for voice and podcasts. Good and High suit most music. Best stays close to the original. Presets that would make your file larger are disabled automatically.

Your files stay private
