About MP3 Bitrate Changer
Change an MP3's bitrate in your browser. Some platforms require a specific constant bitrate (audiobook and podcast hosts often want 128 kbps CBR; some IVR/telephony systems want 64 kbps), and DJs standardise libraries at 320. 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 32–320 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 — 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 — decoding and re-encoding run locally in your browser.
