M4V to MP3 Converter
M4V is Apple’s video container — the format iTunes exports and many Apple apps produce. Drop an unprotected .m4v here and get an MP3 back, converted locally in this page so the file never leaves your computer.

仕組み
Add your M4V
Drop the .m4v file above. Unprotected files from iTunes exports, Apple apps, and camera software all work.
Choose a bitrate
M4V normally carries good-quality AAC audio, so 192 or 320 kbps is worth using.
Download the MP3
Preview it in the page and save. Nothing is uploaded at any point.
主な機能
このm4v to mp3が際立つ理由。
Handles Apple’s AAC audio
M4V files store AAC, which many older devices and editors will not play on its own. The MP3 output plays everywhere.
No upload, no limit
Full-length video files convert without an upload step, so there is no size ceiling and no bandwidth cost.
Honest about DRM
Films and shows bought from the iTunes Store are FairPlay-protected and cannot be converted by any tool. This page tells you rather than failing silently.
Works on any operating system
You do not need iTunes, QuickTime, or a Mac — just a browser. Windows and Linux work identically.
Private and offline-capable
Conversion happens on your machine, and the converter is cached after the first load.
Scriptable via API
POST files to /v1/convert/audio when you need this inside a workflow rather than in a page.
ユースケース
このツールが時間を節約する一般的なシナリオ。
Keep the audio from a home movie
Apple software exports M4V. Pull out narration or music without opening a video editor.
Listen to a recorded talk on the go
Convert a conference recording so it plays in a podcast app instead of a video player.
Play Apple video audio on Android
Android handles M4V inconsistently. MP3 plays on every phone without a special app.
Import into an audio editor
Audacity and similar tools do not open M4V. Convert first, then edit the MP3.
Prepare audio for transcription
Transcription services want audio files. Convert to MP3 and upload a fraction of the bytes.
Automate a library conversion
Batch-convert an archive of M4V exports through the API in a single script.

よくある質問
How do I convert M4V to MP3?
Drop the .m4v file above, choose a bitrate, and click Convert. The AAC audio is decoded and re-encoded as MP3 in your browser, then offered as a download.
Why will my M4V not convert?
Almost always because it is DRM-protected. Films and TV episodes bought or rented from the iTunes Store use Apple FairPlay, and no converter can remove it. Files you created or exported yourself convert normally.
What is the difference between M4V and MP4?
They are nearly the same container. M4V is Apple’s variant, and the only meaningful difference is that it may carry FairPlay DRM. Unprotected M4V files behave exactly like MP4 files.
Do I need iTunes or a Mac?
No. The conversion runs in your browser on any operating system. Windows, Linux, and macOS all work the same way.
Is the audio quality preserved?
Converting AAC to MP3 re-encodes lossy audio, which costs a small amount of quality. At 192 kbps or higher the difference is inaudible in practice.
Is it free?
Yes, the browser converter is free and unlimited. The API is free for 300 credits per month, with paid plans from $19/month.
