How it works
Add M4A files
Drop in one M4A file or a whole batch - or click to choose them.

MP3 is already selected at 192 kbps - change it if you like.
Convert & save
Everything is converted on your device - save each file, or all of them at once.
How to convert M4A to MP3 online
M4A is Apple's audio format (AAC in an MP4 box). It sounds great but not every car stereo, editor or website takes it - MP3 plays everywhere.
Add your M4A files
Drop them on the box above or click to choose. Several at once is fine.
Choose the quality
MP3 is already picked. For MP3, 192 kbps suits most music, 320 kbps is the best, 128 kbps is smallest.
Convert
Press Convert. Each file shows a tick and its new size when it's done.
Save
Save files one by one, or Save all - allow multiple downloads once if your browser asks.
Frequently asked questions
How do I convert iPhone voice memos to MP3?
Share the memo from the Voice Memos app to Files (or AirDrop it to your computer), then drop the .m4a file here and press Convert.
Can it convert protected iTunes songs?
No - songs bought with DRM (before 2009) can't be read by the browser. Normal M4A files work.
Does converting M4A to MP3 lose quality?
A little, as with any MP3. At 192 or 320 kbps you won't hear the difference for most audio.
Can I convert many files at once?
Yes - drop in as many as you like and press Save all when they're done.
Why does Save all ask for permission?
Browsers protect you from sites that download many files at once. Allow it once for swarasound.com and the rest save automatically.
Got lyrics but no song yet?
Turn them into a finished, original song with Swara Sound - free, unlimited, and every file is yours.
