You can use DearMob iPhone Manager to transfer voice memos for free. Alternatively, you can share the voice recordings from iPhone with the following steps.

For Mac users, besides using VideoProc Converter AI, you can also resort to iTunes or Apple Music for help.

  • VideoProc Converter AI supports turning voice memos to mp3 (and m4a, wav, flac, aac, ogg, ac3, aiff, m4r…) and iTunes/Apple Music supports aac, aiff, alac and wav besides mp3.

3. How to Convert Voice Memos to MP3 on iPhone

Tools Needed: The Files App, Safari browser, and Voice Memo apps

With the sandbox mechanism, iOS is a relatively closed system that restricted apps to exchange files and information among others. With the release of Apple's Files app, that kind of restriction can be circumvented to some extent.

To convert voice memos to MP3 on iPhone for free, we need to make a copy of the voice memo into the Files app, so that when we use the online converter on iPhone, we can upload the voice memo from the Files app.

Here is a detailed steps to convert voice memos:

Step 1. Inside the Voice Memo app, enable the Share icon by clicking the Edit button on top right and select one or multiple voice memos.

Step 2. In the Share option, make sure to save the Voice Memo into the Files app.

Step 3. Open the Safari app to visit an online converter that you usually use.


1. It is recommended to use Safari, instead of other browser apps in this scenario.

2. If you don't have a preferable online converter, these two works nicely based on my test:

Step 4. Upload the Voice Memos. Make sure to tap the option that uploads from the Files app.

Step 5. Convert Voice Memos to MP3 online, and download the result file.

Step 6. You can find the converted MP3 file in the Files app.


Besides the default Files app, another popular option is to use the Documents app (developed by Riddle). It has a built-in browser so that you can finish the task in one place.
