How this works
Your browser decodes the M4A file using its own built-in audio engine, then encodes the decoded audio as a real MP3 file using a genuine MP3 encoder running entirely in your browser — no audio is uploaded, and no server-side conversion is involved.

Frequently asked questions
Is this M4A to MP3 converter free?
Yes. It is completely free, with no signup and no limits.
Is my audio uploaded anywhere?
No. The conversion happens entirely in your browser. Nothing is sent to Inqita or stored.
Can I convert an iPhone voice memo with this?
Yes — iPhone voice memos are saved as M4A files, which this tool can convert directly to MP3.
What bitrate should I choose?
128 kbps is a good default for most uses. Choose 192 or 320 kbps for higher quality, or 96 kbps for a smaller file.
Is this a real MP3 file?
Yes. It's encoded with a genuine MP3 encoder, not renamed or repackaged audio, so it plays correctly in any MP3-compatible app or device.
