Video to MP3 with the iPhone Shortcuts App: Does It Work?
Search “video to mp3 iphone” and you'll find people recommending the Shortcuts app. It's a real method and it's free — but it has one catch nobody mentions upfront: Shortcuts cannot produce an MP3 file. Its audio output is M4A.
Here's exactly how the shortcut works, when M4A is good enough, and when you'll want a real converter instead.
How to build the shortcut
Create a new shortcut
Open Shortcuts → + → add the action Encode Media.
Set it to Audio Only
Expand the Encode Media options and toggle Audio Only. Format will be M4A.
Add “Save File”
Append a Save File action so the result lands in Files. Optionally enable “Show in Share Sheet” so you can run it from any video.
Where the shortcut falls short
- No MP3. M4A is fine on Apple devices, but car stereos, older players, some editors and upload forms still demand .mp3.
- No trimming. You get the entire audio track — cutting out one section means another app anyway.
- No batch mode. One video at a time, run manually.
- Fragile. If an action gets misconfigured, it fails silently or saves in the wrong place — a common complaint in the Reddit threads that recommend it.
Shortcut vs converter app — honest comparison
If you need M4A once in a while and don't mind the one-time setup, the shortcut is genuinely fine — that's why we documented it here. Use it.
A converter app earns its place when you need true MP3 output, want to trim before saving, convert several files at once, or just don't want to maintain a DIY shortcut. Video to MP3 Converter does all of that on-device, with WAV and AAC as bonus formats.
