Video to MP3 Converters
Extract audio from MP4 video and save as MP3. Ideal for lectures, Zoom recordings, screen recordings, and any MP4 file — compact output plays everywhere.
Convert iPhone and QuickTime MOV files directly to MP3. No quality loss vs. the source audio, no upload required. Works in Safari on iOS too.
Need WAV output instead? MP4 to WAV and MOV to WAV are available for editing-quality uncompressed output.
Why MP3?
MP3 is the universal audio format. It plays natively on every smartphone, music app, podcast platform, and browser without any additional software. When you extract audio from a video to share it — as a podcast episode, a voice memo, a recorded lecture, or a music clip — MP3 is almost always the right choice: the files are small, broadly compatible, and indistinguishable from the source at 192 kbps for voice and everyday music.
The audio track inside an MP4 or MOV file is typically stored as AAC, which is already compressed. Converting to MP3 involves one re-encode. At 192 kbps the output is transparent for voice recordings, lectures, meetings, and most music. AudioUtils uses FFmpeg compiled to WebAssembly, so this entire process runs inside your browser — no server, no upload, no privacy risk. If you later need to edit the MP3 in a DAW, you can convert it to WAV to avoid any further generational loss.
When to Convert Video to MP3
Podcast from video
Record your podcast episode on camera, then extract the audio track as MP3 and publish directly to Spotify, Apple Podcasts, or any RSS feed — no separate audio recorder needed.
Lecture / meeting audio
Turn Zoom or Teams MP4 recordings into MP3 for transcription, replaying at 2× speed, or sharing with colleagues who missed the call — without distributing the full video file.
iPhone interview
Shot an interview on your iPhone? Convert the MOV file to MP3 for easy sharing via email or upload to transcription services like Otter.ai or Rev without the video overhead.
Music / live performance
Recorded a live gig or acoustic session on your phone? Extract the audio as MP3 and add it to your library or share it without keeping the large video file around.

Frequently Asked Questions
What video formats can I convert to MP3?
MP4 and MOV are supported. MP4 covers Zoom recordings, screen recordings, Android videos, and most camera footage. MOV covers iPhone recordings and QuickTime exports — between the two, you can convert virtually any common video file to MP3.
Does my video file get uploaded to a server?
No. AudioUtils runs entirely in your browser using WebAssembly. Your video file never leaves your device — nothing is uploaded or stored on any server. Safe for private meetings, unreleased content, or any sensitive recording.
What MP3 bitrate does the output use?
192 kbps by default — high quality for both voice and music, indistinguishable from the source for most listeners. Higher bitrates produce larger files with diminishing returns; 128 kbps is acceptable for voice-only content.
Will the video's audio quality be affected?
Minimally. The audio in MP4 and MOV files is already compressed as AAC. Converting to MP3 at 192 kbps involves one re-encode. For voice recordings, lectures, podcasts, and most music the result is indistinguishable from the original.
Does it work on iPhone in Safari?
Yes. AudioUtils works in Safari on iOS 15.4 and later. Select a MOV or MP4 from your Camera Roll, Files app, or iCloud Drive and convert to MP3 directly on your iPhone — no app download required.
Is this free?
Yes. The free tier lets you convert with a 30-second preview limit so you can verify quality before committing. Pro ($9/month) removes the limit entirely and supports full-length conversions for files up to 500 MB.
