iPhone Voice Memos
Recordings come off an iPhone as M4A. Converting makes them playable and uploadable anywhere that expects MP3.
192 KBPS MP3 · TAGS & CHAPTERS KEPT · NO INSTALL
M4A to MP3, tags and chapters intact.
Drop in M4A, M4B, M4R, or MP4 and M4V video and get 192 kbps MP3s back with the title, artist and album still attached — and, for audiobooks, the chapter marks too. This is the Apple audio format, so it is what your Voice Memos, iTunes rips and downloaded audiobooks already are. Up to 50 at a time, no install, no watermark.

How to convert M4A to MP3 — two steps

converted.mp3
192 kbps · tags intact
Grab it within the hour. Download links expire 60 minutes after conversion. Whether the MP3 is bigger or smaller than what you sent depends on what was inside the M4A — see below, because it surprises people either way.
Why a paid converter is the one worth using
Free audio converters pay their server bill with ads, size caps and daily limits — and plenty of them strip your tags, drop audiobook chapters, and encode at 128 kbps. M4A to MP3 Cyborg is funded by you, so it works for you.
50 files in one pass
Queue an album, an audiobook or a folder of voice memos instead of feeding them in one at a time.
Anonymous & private
Voice memos and personal recordings stay yours. We don't track who converts what, and files are never handed to third parties.
Chapters survive
An M4B audiobook keeps its chapter marks in the MP3. Most converters flatten a twelve-hour book into one unnavigable file, which is the difference between usable and useless.

How €1 compares to “free”
| M4A to MP3 Cyborg | Free online converter | Desktop app | |
|---|---|---|---|
| Files per batch | 50 | 1–2 | Many |
| File size cap | 200 MB per file | Capped, often 20–100 MB | None |
| Output bitrate | 192 kbps | Often 128 kbps | You choose |
| Nothing to install | Desktop app | ||
| Ad-free & untracked | Ad-funded | ||
| Price | from €1 | Free (ad-funded) | €20–60 |
Free M4A-to-MP3 tools exist because ads pay for them — and they still cap your upload size, throttle you after a couple of files a day, strip your tags, flatten audiobook chapters, or encode at 128 kbps without telling you. M4A to MP3 Cyborg starts at €1 for a day, installs nothing, takes 50 files at a time at up to 200 MB each, and encodes every one at 192 kbps with tags and chapters intact.
What actually happens to your file
M4A is a container, not a codec, and what is inside decides how this goes. Most M4A files hold AAC, which is already lossy — converting those is a second lossy pass and the MP3 comes out larger. A few hold ALAC, Apple's lossless codec, and those shrink dramatically. Both are normal.

AAC inside: expect it bigger
1.5×An ordinary M4A holds AAC, which is more efficient than MP3. Matching its quality costs more bits, so a 128 kbps AAC becomes roughly one and a half times the size as a 192 kbps MP3. You are converting for compatibility, not to save space.
ALAC inside: expect it smaller
1/8If your M4A is Apple Lossless, it is uncompressed-grade audio and the MP3 will be a fraction of the size — around an eighth in our tests. Same tool, opposite outcome, decided entirely by what is in the file.
Tags and chapters come along
ID3Title, artist and album transfer into the MP3, and M4B chapter marks are written as ID3 chapter frames — verified, not assumed. A long audiobook stays navigable.
Voice Memos and ringtones
iOSiPhone Voice Memos are M4A and iPhone ringtones are M4R. Both convert here, and both keep a proper bitrate instead of being dropped to something tinny because they happen to be mono.
MP4 and M4V video too
MP4Drop in an MP4 or M4V and you get just the soundtrack back as MP3. Useful when all you wanted from a video was the audio.
The honest caveat: DRM
Music bought from the iTunes Store before 2009 is FairPlay-protected M4P, and no converter can decrypt it — not this one, not any of them. The uploader will accept the file and the conversion will fail. Anything you ripped, recorded or downloaded DRM-free is fine.
Need uncompressed audio instead? MP3 to WAV Cyborg produces PCM WAV.

When you need the MP3
M4A is what Apple hands you. MP3 is what everything else expects. Here is where the gap shows up:
R
Audiobooks on a non-Apple player
M4B is an Apple format. Converting keeps the chapters and lets the book play on an Android phone or a plain MP3 player.
P
Car stereos and older players
Plenty of head units read MP3 from a USB stick and ignore M4A entirely.
F
Pulling audio out of an MP4
Drop the video in and get the soundtrack back, without a separate extraction step or a second tool.
T
Uploading to a service
Podcast hosts, transcription tools and upload forms very often accept MP3 and nothing else.
S
Sending a recording to someone
MP3 is what the person at the other end can definitely open, whatever phone or computer they use.
Whatever the destination, upload your M4A files and get tagged MP3s back.
Different format — or a different job?
Looking for the MP3 downloader rather than a converter? That's MP3 Cyborg. Starting from a lossless format? FLAC to MP3 or WAV to MP3. Coming from Ogg or Opus? OGG to MP3. Want the audio out of any video format, not just MP4? Extract Audio — all included in one account.
Common questions
Getting started
What is M4A to MP3 Cyborg?
A web app that turns Apple audio files into 192 kbps MP3s with their tags intact. It accepts M4A, M4B, M4R and M4P, plus MP4 and M4V video whose soundtrack is extracted — up to 50 at a time, nothing to install.
Does it work on a phone?
Yes. It works on all Android phones, and on iOS 12 and higher. Conversion happens on our servers, so a phone finishes as fast as a desktop — you only need a browser. That matters here, since the files often start life on an iPhone.
How do I convert M4A to MP3?
Two steps. Drag your files onto the uploader at the top of this page — up to 50 at a time — then download the results individually or as a single ZIP. There is nothing to install and no settings to choose; every file comes back at 192 kbps with its tags.
Quality, size & batches
Will I lose quality?
It depends what is inside. Most M4A files hold AAC, which is already lossy, so converting is a second lossy pass — small at 192 kbps, but real and not reversible. If your M4A holds Apple Lossless (ALAC), then this is the first lossy step, exactly like converting a FLAC. Either way you cannot get quality back by converting the MP3 onwards.
Why is my MP3 bigger than the M4A?
Because AAC is a more efficient codec than MP3. It fits the same perceived quality into fewer bits, so matching it in MP3 costs more space — a 128 kbps AAC typically becomes about one and a half times the size as a 192 kbps MP3. If instead your file shrank dramatically, it was Apple Lossless rather than AAC.
How many files can I convert at once?
Up to 50 per batch. Filenames are preserved, and you can download the results individually or as a single ZIP.
Is there a file size limit?
200 MB per file. That covers most music and voice memos easily, but a single long audiobook can exceed it — if an M4B is rejected, split it before uploading.
Do audiobook chapters survive?
Yes. M4B chapter marks are written into the MP3 as ID3 chapter frames, so a long book stays navigable instead of collapsing into one continuous file. This is worth checking before you use any other converter, because losing chapters is the usual outcome elsewhere.
Can I convert music I bought from iTunes?
Only if it is DRM-free. Purchases from before 2009 are FairPlay-protected M4P files, and no tool can decrypt those — the upload will be accepted and the conversion will fail. Everything Apple has sold since 2009 is DRM-free and converts normally, as does anything you ripped or recorded yourself.
Can I convert an MP4 video to MP3?
Yes. Drop the MP4 or M4V in and you get its soundtrack back as an MP3; the picture is discarded. For video in other containers — MKV, AVI, MOV and so on — use Extract Audio instead.
Pricing, privacy & limits
How much does it cost?
A €1 day pass gives you 24 hours of unlimited conversions. Yearly (€6) and lifetime (€30) plans are also available (+ VAT). Every plan unlocks all 79 AppsCyborg tools, not just this one.
How long does my download link stay valid?
60 minutes. After that the link expires and the converted files are removed — just re-run the conversion if you need them again.
Do you track or keep my files?
No. We don't run ad or analytics tracking on what you convert, and your files are never sold or shared for marketing. Uploaded audio is processed only to build your MP3s and is removed once the 60-minute download window closes.
Is there a limit on how often I can convert?
No. While your day pass, yearly or lifetime plan is active you can run as many 50-file batches as you like — there is no monthly quota and no per-conversion charge.
Still have a question?
We usually reply within a day.
Your MP3s are minutes away.
