Frequently asked questions

Where do I find my iPhone voice memos?

In the Voice Memos app, you can share the recording and save it to Files; that gives you the .m4a.

My M4A won't open. What should I do?

Try another browser (Chrome or Safari). If the file has iTunes protection (DRM), it can't be converted.

Are my recordings uploaded?

No. Everything is done on your device.

About this tool

M4A is Apple's audio format: iPhone voice memos and many iTunes downloads use it. Some players and programs don't accept it, which is why it's worth converting to MP3.

Your browser decodes the audio, so the result depends on its AAC support. It works in Chrome, Edge and Safari; on other systems it may require codecs installed on the device.
