Convert an M4A File to MP3
M4A to MP3 converter takes an Apple-format audio file (an iTunes purchase, a voice memo, a GarageBand export, an Apple Music download) and gives it back as an MP3 that plays on any device or player. Upload the file and download the converted copy, no software or account setup beyond signing in.
What you get:
- An M4A file converted to MP3, ready to download
- Files up to 2 GB in the free online tool on this page, with no set file size limit in the app
- bulk upload of multiple files, so several M4A files convert in one batch
- A transcript of the audio, with speaker labels, in 100+ languages
- AI chat with any recording, so you can ask the converted file a question instead of listening back
- Export the transcript as PDF, DOCX, TXT, SRT and VTT
- Free plan: 3 uploads, lifetime, each with the transcript and AI chat included
How to Convert M4A to MP3
- Upload your M4A file: from a computer, phone, or tablet. The free online tool on this page takes files up to 2 GB; the ScreenApp app has no set file size limit.
- Let it process: the file converts to MP3 and the audio transcribes at the same time. Both are ready in your library once processing finishes.
- Download the MP3: open the file and download it. The transcript, speaker labels, and AI chat are attached to the same recording.
Transcript quality follows the audio: clear narration transcribes cleanly, and a recording with heavy background noise or several people talking over each other will have more gaps. See how we measure accuracy.

Who Converts M4A to MP3
iTunes and Apple Music users convert purchased or downloaded tracks to MP3 so they play on non-Apple devices, older MP3 players, and software that does not open M4A.
iPhone voice memo users convert recordings saved as M4A to MP3 for sharing with people or uploading to platforms that expect the MP3 format.
Podcasters and audio creators convert M4A recordings to MP3 because most podcast hosting platforms expect that format for upload.
Android device owners convert M4A files to MP3 because some Android music apps have limited M4A support.
Audio collectors and archivists convert M4A music libraries to MP3 for long-term compatibility with players and editing software that expect the older format.
