This tool decodes your MP3 and re-encodes it at exactly the CBR bitrate you choose, entirely on your device.

Frequently asked questions

What bitrate do podcast platforms want?+

Most hosts recommend 128 kbps CBR for stereo or 96 kbps for mono speech; Apple's spec accepts 32โ€“320 kbps. When in doubt, 128 kbps CBR is the safe universal choice.

Does raising the bitrate improve sound?+

No. Detail discarded by the original encode is gone forever โ€” raising the bitrate only makes the file bigger. Choose a higher bitrate only when a platform demands it.

CBR or VBR?+

This tool produces CBR (constant bitrate), which is what platforms with strict specs almost always require, and what seeking-sensitive players handle best.

Is my file uploaded?+

No โ€” decoding and re-encoding run locally in your browser.
