How to Convert MOV to MP3 (Extract Audio from iPhone & QuickTime)

MOV is QuickTime's container format. If you recorded a video on an iPhone, iPad, Mac (QuickTime or Screen Recording), or most DSLR cameras in video mode, you got a MOV file. Inside that container sits a video track and an audio track — usually AAC-encoded audio.

Sometimes you only need the audio. A voiceover you filmed on your phone, an interview you shot as a video, a live performance you want to save as music, or a tutorial screencast where you want the narration without the screen recording. Converting to MP3 gives you a small, universally playable audio file and lets you delete the bulky video.

The 30-Second Version

1. Open the MOV to MP3 converter. 2. Drop your .mov file (or tap to select on iPhone). 3. Pick a bitrate. 192 kbps for most cases; 128 kbps for podcasts and voice-only. 4. Click Convert. The tool extracts the audio track and re-encodes it as MP3. 5. Click Download.

The original MOV is never modified. The tool reads it, extracts the audio track, and produces a new MP3 file. Your video stays intact on your device.

It Works with iPhone Videos

iPhone recordings from the Camera app save as .mov files with AAC audio (unless you specifically enabled "Most Compatible" in Settings, in which case they're .mp4 — use the MP4 to MP3 tool instead).

Supported iPhone sources:

• Camera app (front and back)
• Screen Recording (Control Center)
• FaceTime captures (saved locally)
• Shared videos received via Messages or AirDrop

Sync the video to Files (iCloud Drive or On My iPhone), open audioutils.com in Safari, select the file, convert, save.

It Works with Mac Screen Recordings

macOS screen recordings from QuickTime or Command+Shift+5 save as .mov. So do videos exported from iMovie, Final Cut Pro, or Photo Booth. Drop them in and extract audio the same way.

Useful for extracting:

• Narration from tutorial screencasts
• Audio from Zoom recordings saved locally (the ones that show up as .mov in your Documents/Zoom folder)
• Music from a live performance you captured
• Interview audio from a video call you recorded

Which Bitrate for MOV to MP3?

The source audio in most MOV files is AAC at 128–256 kbps. The MP3 output can't add quality that wasn't in the source, so match or go slightly above:

• 192 kbps — safe default. Preserves all the quality in a typical iPhone recording.
• 256 kbps — bump up if the MOV has high-quality audio (external mic, professional camera).
• 128 kbps — podcast standard. Good for interview and voice-only content where file size matters.

Don't go above 256 kbps when extracting from a phone MOV — you're just making the file bigger without improving quality. If you need the absolute highest quality and plan to edit further, extract to WAV instead using MOV to WAV — no transcoding loss.

File Size Expectations

A 10-minute 1080p iPhone video is typically 200–400 MB total, but the audio track is usually only 10–20 MB as AAC. Converting to MP3:

• 192 kbps → ~14 MB for 10 minutes
• 128 kbps → ~9.4 MB for 10 minutes

Converting is fast — the video isn't being re-encoded, just discarded — so a 10-minute clip processes in about 5–10 seconds on a modern laptop.

Multi-Track MOV Files

Most phone and camera MOV files have a single audio track. Final Cut Pro exports and some professional cameras produce MOV files with multiple audio tracks (e.g., a stereo mix plus a commentary channel). The converter extracts the first (primary) track. For multi-track extraction, use a desktop tool like ffmpeg directly.

Screen Recordings from Zoom / Teams / Meet

Zoom saves local recordings as .mov (or .mp4, depending on version). Drop the .mov directly into the converter. For .mp4, use the MP4 to MP3 tool — everything else works the same way.

Microsoft Teams and Google Meet typically save recordings as .mp4, so those also route through MP4 to MP3.

Troubleshooting

"Unsupported codec" or silent output. Rare, but possible on MOV files from older cameras using non-AAC audio (e.g., PCM). The converter handles standard AAC; exotic codecs may need a desktop tool.

File too large. Free tier accepts up to 20 MB MOV files, which covers short clips only. Pro handles up to 500 MB (roughly 20+ minutes of 4K iPhone video). For very long videos, trim first in iMovie or QuickTime.

Audio is quiet. The extraction preserves the source volume. If the original recording was quiet (phone mic in a noisy room), the MP3 will be quiet too. Normalize or boost in an audio editor after extraction.

iPhone tells me the format isn't supported. Make sure you're opening the file in a browser that supports WebAssembly with SharedArrayBuffer (Safari 15.4+ on iOS, current Chrome/Firefox). Older iOS versions can't run the converter.
