Why convert M4A to MP3?
iPhone voice memos and iTunes downloads use M4A, which some players, cars and older devices don't support. MP3 is the most widely supported audio format there is.

Frequently asked questions
Is it really free?
Yes. Converting M4A to MP3 is free with no sign-up and no watermark. The free plan handles several files per batch; an optional premium licence removes ads and raises the limits.
Are my files uploaded anywhere?
No. Your M4A files are read and converted by your browser on your own device. You can confirm it by opening your browser's developer tools and watching the Network tab while you convert: no file upload ever appears.
Will I lose quality?
That depends on the target. Lossless targets such as PNG keep every pixel. Lossy targets such as JPG and WebP let you choose the trade-off between file size and quality with the presets or the fine-tune slider.
