Re-encode 320kbps voice recordings at 96–128kbps and reclaim most of the space.
Smaller audio uploads faster and transcribes cheaper in automated flows.
Upload above, check the predicted size at each quality level, pick one, download. For voice, level 2 (~128kbps) is usually transparent; level 3 squeezes hardest.
The size prediction tells you before you run — typically 50–75% smaller for high-bitrate voice recordings, less if the file is already low-bitrate.
Re-encoding lossy audio always costs a little, but going from 320kbps to 128kbps for speech is rarely audible. We show the prediction so you can choose your trade-off.
Yes — loudness is normalized during compression, so the output doesn't come out quieter than the original.
