FAQ
How do I convert M4A to MP3?
Drop the M4A in, pick MP3 and a bitrate, and hit convert. iPhone voice memos are M4A, so this is the quickest way to turn one into an MP3 that plays anywhere.
Which formats can I convert between?
Input: anything your browser can decode — MP3, M4A/AAC, WAV, OGG, FLAC and more. Output: MP3 (128, 192 or 320 kbps), WAV (uncompressed 16-bit), or M4A (AAC).
Does converting lose quality?
WAV output is lossless. MP3 and M4A are compressed — at 320 kbps the difference from the original is inaudible for almost everyone. Converting an already-compressed file can't add quality back, so pick the bitrate that matches your use.
Is my audio uploaded to a server?
No. Decoding and encoding both happen in your browser, so the file never leaves your device. That's also why there's no file-size limit or queue.
