Compress Audio, answered.

How do I compress an audio file? +

Upload any common audio format above. You'll see predicted output sizes for each quality level before you commit — pick one and download.

What's the best compression level for voice? +

Level 2 is the sweet spot for speech: significant size savings while keeping the speech band fully intact. Level 3 is for when the size cap is brutal.

Audio vs MP3 compression — what's different? +

This tool accepts every format (WAV, FLAC, M4A, OGG…) and re-encodes to an efficient target; the Compress MP3 tool is the focused version for MP3-in, MP3-out.

Will it hurt transcription accuracy later? +

No — compression here protects the frequency range speech recognition uses. Cleaned, normalized, compressed audio often transcribes better than the original.
