How to Extract Audio from Video on iPhone

Quick answer
To extract audio from a video on iPhone, install the free ConvertEase app, tap Video, choose Extract Audio, pick your video (MP4, MOV, AVI, MKV, or WEBM), and tap Extract. The audio is pulled from the video entirely on your iPhone and saved to Files in seconds — no upload, no account, works offline.
Extracting audio from a video is one of those tasks that looks simple but has no obvious one-tap solution built into iOS. You might want the soundtrack from a video someone shared with you, a voiceover you recorded as a video clip, a lecture captured on your phone, or the background music from a clip before you delete the original. Whatever the reason, you need the audio track out — without re-recording the screen or uploading the video to an online service.
Online audio extractors work, but they require uploading the whole video first. That is slow on mobile data, consumes your data allowance, and is a poor fit for personal or sensitive recordings. A dedicated on-device app processes the video entirely on your iPhone, so the clip never leaves your device.
What does "extract audio from video" actually mean?
A video file contains at least two streams: the video track (frames) and the audio track. Extracting audio means saving only the audio stream to a standalone audio file. The result is typically an M4A file — Apple's native high-quality audio container, which plays directly in the Music app, Files, Voice Memos, and any iPhone audio player.

This is different from converting the video to another video format — such as converting MOV to MP4 — which keeps the video track intact. Audio extraction removes the video entirely and keeps only the sound. Because no re-encoding is needed, the process is fast and the audio quality is identical to the original.
How to extract audio from a video on iPhone (step by step)
The cleanest method is a dedicated on-device tool. No upload, no account, no waiting for a remote server to finish:
- Download ConvertEase free from the App Store and open it.
- Tap Video, then choose Extract Audio.
- Select your video from Files or Photos — MP4, MOV, AVI, MKV, and WEBM all work.
- Tap Extract. The audio is saved to your Files app in seconds, processed entirely on your iPhone.
Once the audio file is in Files, you can share it via iMessage, Mail, AirDrop, or any app that accepts audio files. If you specifically need MP3 rather than M4A — for Android compatibility or a podcast platform — see the convert MP4 to MP3 guide for the extra conversion step.
Extract audio: app vs. iMovie vs. online extractor
There are a few ways to get audio out of a video on iPhone. Here is how they compare in practice:
| Method | Ease of use | Privacy | Best for |
|---|---|---|---|
| ConvertEase (on-device app) | One tap, any video format | Files never leave your iPhone | Quick extraction, private videos, offline use |
| iMovie "Detach Audio" | Requires a project, multiple steps | Stays on device | Video editors already working in iMovie |
| Online audio extractor | Simple browser upload | Full video uploaded to a server | Non-sensitive clips on a strong Wi-Fi connection |
iMovie can detach an audio track, but it requires creating a project, importing the clip, detaching the audio, then exporting it — four or five steps for what should be a single tap. Online extractors are simpler to start, but force you to upload the entire video file to a remote server, which can take minutes for a large clip and is not suitable for personal recordings.
Tip: check the audio before deleting the original video
After extracting, tap the saved M4A file in the Files app and press play to confirm the audio sounds correct before removing the original video. Some videos — especially clips recorded in unusual conditions or with very low volume — can have a near-silent audio track. If the extracted file sounds too quiet, keep the original video as a backup. And if large video files are still eating up storage space, compress your videos on iPhone to shrink them without losing the footage.
