How to convert M4A to MP3
- Drop your M4A file on the box above, or tap it to choose. You can pick several files at once.
- MP3 is already selected. Adjust the quality if you like (192 kbps is a good default, 320 kbps for the best quality).
- Tap the download button next to each file. Your MP3 is saved to your Downloads folder.
M4A (AAC audio) is what iPhones and Apple apps save, but many players, websites and car stereos want MP3. Drop the M4A in and download an MP3.

Frequently asked questions
Can I convert iPhone Voice Memos to MP3?
Yes. Share the memo to Files (Save to Files), then open this page in Safari, tap the box and choose the memo. The MP3 is saved to your Downloads.
Do protected iTunes purchases work?
Only DRM-free files work. Old iTunes songs bought before 2009 with DRM (M4P) can't be opened by any browser.
Which bitrate should I choose?
Voice memos sound fine at 128 kbps. For music, use 192 or 320 kbps; going higher than the M4A's own quality doesn't add detail.
Can I convert several files at once?
Yes. Choose or drop as many files as you like. They are converted one after another and each gets its own download button.
Are my files uploaded?
No. The conversion runs inside your browser on your own device. Your audio is never sent to a server, so it works with private and unreleased recordings.
Is it really free?
Yes. No sign-up, no watermark, no daily limit. Very long files (over about an hour) may be too big for a phone's memory.
