How do I convert iPhone voice memos to MP3?

Export the voice memo from the Voice Memos app (Share → Save to Files), then drop the .m4a file into FileConvertir. The MP3 is ready in seconds.

Can I convert Apple Music or iTunes M4A to MP3?

Yes for unprotected M4A files (your own recordings, free songs, podcast files). DRM-protected M4P files from older iTunes Store purchases cannot be converted by any browser tool — that's a deliberate Apple restriction.

Are my audio files uploaded to a server?

No. FFmpeg runs in your browser via WebAssembly — your files never leave your device. There is no upload, no logging, and no server-side storage.

What bitrate is the MP3?

The MP3 is encoded at 192 kbps CBR, which is high quality for music and excellent for voice. This roughly matches the perceptual quality of the M4A source.

Will I lose audio quality?

Some quality loss is unavoidable when converting between two lossy formats (M4A/AAC → MP3). At 192 kbps the loss is inaudible to most listeners on most playback equipment.

Why won't my car stereo play M4A files?

Many car stereos and older Bluetooth speakers only support MP3 and WMA. Converting to MP3 fixes the playback issue.

Can I batch convert M4A to MP3?

Yes — up to 20 files at once. Drop them in, wait a moment, download the ZIP.

How long does it take?

Roughly real-time on a modern laptop — a 3-minute song converts in about 3 seconds. First conversion takes a bit longer because FFmpeg.wasm has to load.

What's the max file size?

100MB per file. A typical 1-hour podcast at 192 kbps is around 86MB, so this fits.
