Convert M4A to MP3
M4A is Apple’s AAC container — fine on iPhones and Macs, but some players and upload forms still reject it. This re-encodes M4A to a universally playable MP3 with WebCodecs in your browser, so the file stays on your device and there is no size cap.
全部在你的浏览器里完成，文件不会上传。

常见问题
Can it convert iPhone voice memos?
Yes — iPhone voice memos are M4A, so drop one in and get an MP3 back. If you want the words instead of the audio, transcribe the memo with ScribeToAny to get timestamped text.
Is anything uploaded?
No. Everything runs with WebCodecs in your browser tab — the file is never sent to a server, which is why there is no account and no size limit. Chrome, Edge and Firefox work best.
