The formats
M4A
Apple's audio format, used by iPhone voice memos and iTunes. It is AAC in an MP4 container: good quality for a small size, but some players and websites do not accept it.
MP3
The universal audio format. It compresses with loss, almost inaudibly at 192 kbps, and plays on every device, player and app. It is the format to aim for when sharing audio.
Your files stay with you
The conversion runs in your browser, with your device's decoders. No file is uploaded, no copy is kept, and nobody but you sees your photos or videos. You can check it in the Network tab of your browser's developer tools: none of your files goes out.
Frequently asked questions
How do I get a voice memo off the iPhone?
In Voice Memos, tap the memo, then Share and Save to Files. Then open this page in Safari and drop the file.
What about tracks bought on iTunes?
Old copy-protected tracks cannot be read by the browser, so they cannot be converted. Tracks without protection go through fine.
Is the converter really free?
Yes, with no sign-up, no watermark and no limit on the number of files. The conversion runs on your device and costs us nothing, so there is nothing to charge you for.
Are my files sent anywhere?
No. They are read and converted in your browser, then saved straight to your device. No server receives them.
Is there a maximum size?
The limit is your device's memory. Photos and audio files go through without trouble; for a video of several gigabytes, a computer does better than a phone.
Does it work on a phone?
Yes, on iPhone and Android, in Safari, Chrome or Firefox. For video, an up-to-date browser is needed: it provides the decoders being used.
