About this tool
Why convert to MP3?
MP3 keeps files small and plays everywhere, so it is the safest choice for sharing, podcasts and adding a voiceover to an editor.
Private by design
Most online converters upload your file to their servers. This one does the work locally, so recordings of meetings, interviews or unreleased music never leave your computer or phone.
Frequently asked questions
How do I convert an iPhone voice memo to MP3?
Share the memo from the Voice Memos app to Files or AirDrop it to your computer. It arrives as an M4A file. Drop it here and download the MP3.
Will converting M4A to MP3 lower the quality?
Both formats are compressed, so there is a small generation loss. At the 192 kbps this tool uses, speech and most music sound the same to the ear.
Is my M4A file uploaded anywhere?
No. The conversion runs inside your browser on your own device. Your file is never sent to FacelessGenie or any server, which also means there is no upload wait.
Is there a file size limit?
You can convert files up to 1 GB. Very long files take longer because your device does the work, but the page shows progress while it runs.
Which browsers work?
Recent versions of Chrome, Edge and Safari handle every format here. Firefox works for most audio files. If a file will not open, try Chrome or Edge, which support the widest range of MP3 encoding.
