The M4A to MP3 converter is part of this page and runs inside your browser. Your audio files are never sent to toany or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
iPhone Voice Memos, GarageBand exports and iTunes purchases are M4A. Car stereos, older MP3 players, some editing and transcription tools and many upload forms only take MP3. Both formats are lossy, so the audio is decoded and compressed a second time; at 192 kbps or higher the difference is hard to hear for speech and most music.
The defaults suit most files. Under Options you can choose the bitrate and trim the start and end.
The conversion uses your browser's own video and audio codecs (WebCodecs), with hardware acceleration where the device has it; the file is read from disk as it goes and can be up to 2 GB. Where the browser lacks a codec, the page falls back to the compatibility engine. MP3 is written at 192 kbps unless you choose another bitrate.
M4A is an MP4 file that contains only audio, usually AAC. iPhone Voice Memos and the iTunes Store use it. It sounds better than MP3 at the same size but is not accepted everywhere MP3 is.

A little, in theory: the audio is compressed a second time with a different codec. At 192 kbps and above most people cannot hear a difference.
No. The M4A to MP3 conversion runs inside your browser, on your own phone or computer. The file is not sent to toany or to anyone else.
MP3 is a lossy format, so a small amount of detail is traded for a smaller file. At the default setting the difference is hard to notice. You can choose the bitrate under Options.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because toany runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the M4A file, press Convert and save the MP3. There is nothing to install.
Yes. Files up to 2 GB are accepted. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
