How do I convert an iPhone voice memo to MP3?
Share the voice memo to Files or send it to your computer, open this page, drop the M4A file and download the MP3. Voice Memos saves recordings as M4A, so no other step is needed.
Convert M4A to MP3
Turn iPhone voice memos and other M4A audio into MP3 files.
Your files never leave this device.
Drop your M4A audio here, keep MP3 selected and download the result. M4A is the audio format Apple uses for voice memos and many downloads, but some players, car stereos and older devices only understand MP3. The conversion runs in your browser, so your recordings are never uploaded.
How to use
- Drop your M4A files onto the page.
- Keep MP3 selected; 128 kbps is plenty for voice, and 192 kbps is the default.
- Trim the start and end if the memo has dead air.
- Download the MP3 files, or all of them together as a ZIP.
Frequently asked questions
What is the difference between M4A and MP3?
M4A usually holds AAC audio, a newer compressed format that sounds slightly better than MP3 at the same size. MP3 is older but plays on more devices, which is the reason to convert.
Will the MP3 lose quality compared with the M4A?
A little, because both formats are lossy and the sound is compressed a second time. At 192 kbps or higher, voice memos and most music show no audible difference.
Why won't my M4A file open?
It may be protected. Files with copy protection, like some old store purchases, cannot be opened here. A normal M4A, such as a voice memo, opens in every browser.
Can I convert several voice memos at once?
Yes. Add all the files together and download them in a single ZIP. Each memo becomes its own MP3.
Is M4A the same as AAC?
Almost. AAC is the compression method, while M4A is the file type that usually carries it. This tool accepts both M4A and plain AAC files.
What bitrate should I use for a voice memo?
128 kbps is plenty for speech and keeps the file small. If you also tick mono, the file gets smaller still, and a single voice sounds the same.
Why would I need MP3 instead of M4A?
Apple devices play M4A without trouble, but the rest of the world is less predictable. A car stereo with a USB port, an old MP3 player, a web form that accepts only MP3 or a podcast platform that asks for a specific file may reject M4A. Converting the file is a one-minute fix that avoids those errors.
It is also a good way to back up an archive. Dozens of old memos kept as M4A can cause trouble when they move between devices and programs, while MP3 copies stay playable almost everywhere.
How do I get a voice memo off my iPhone?
In the Voice Memos app, open the recording, tap the share button and choose Save to Files, or send it to yourself by email or AirDrop. Once the M4A is on your device, select it on this page. If you are on a Mac, the memo can also be dragged out of the app onto your desktop first.
A recording may include long pauses at the start or end. Set start and end seconds to cut them. The main video to MP3 converter lists every option, including mono and the choice of bitrate.
What settings keep voice memos small?
Speech needs far less data than music. For a lecture, an interview or a meeting, 128 kbps with mono gives a clear recording that is often a few megabytes even for an hour of talking. A song, on the other hand, deserves 192 kbps or more.
Before you send a memo to someone, listen to the MP3 once. Background noise stays in the file, and the converter does not remove it. If a memo will be shared, a short test listen of the first and last minute is usually enough to catch problems.
What if the memo is only one part of a larger task?
If you plan to write out what was said, the word counter shows how many words and how much speaking time the text will have. If your audio is a large uncompressed recording, such as one from a studio, the WAV to MP3 page explains the size difference. And if the sound is inside a video, MOV to MP3 covers iPhone clips.

- Only files on your device work; there is no downloading from links.
- Files are limited to 2 hours of audio; very long recordings can fail on phones.
