How do I convert MOV to MP3?

MOV is Apple's QuickTime container — the native recording format of iPhone cameras and the default export of many Mac video tools. Structurally it is the direct ancestor of MP4, and like MP4 it usually carries AAC audio (or, from some pro recorders and screen captures, uncompressed PCM). Converting MOV to MP3 drops the video stream and encodes just the soundtrack.

iPhone videos are the most common source: extracting the audio from a recorded concert clip, a video voice memo, or an interview filmed on a phone. Since the video track dominates the file size, the output MP3 is tiny compared to the MOV — minutes of iPhone 4K video shrink from gigabytes to a few megabytes of audio.

If the MOV's audio is AAC, use 192 kbps+ MP3 to keep transcode loss inaudible; if it is PCM (common in screen recordings and pro camera footage), you are converting from lossless and 320 kbps yields a transparent result. Duration is preserved exactly; use Trim MP3 afterwards to isolate the section you need.

Reasons to convert MOV to MP3 usually come down to compatibility, file-size, or specific feature requirements. Common situations:

• An app or platform only accepts MP3 uploads.
• You need a feature unique to MP3 (e.g. lossless editing, chapter markers, smaller streaming size, etc.) that MOV doesn't provide.
• You're optimising file size — modern formats often produce smaller files than the older format you started with.
• You need a single archival format across a project so files behave consistently in the same viewer.

1. Open the MOV → MP3 tool on mp3.now.
2. Drag your MOV file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
3. The output is fixed to MP3. If the format supports extra options (bitrate, sample rate, channels, volume normalization), tweak them in the options panel.
4. Click Convert. The job runs on our server and finishes in a few seconds for typical tracks.
5. Download the result. Files stay in storage for 24 hours and are then permanently deleted.

The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.

• iPhone-recorded MOV audio is AAC — 192 kbps MP3 output preserves it cleanly.
• Screen recordings and pro camera MOVs often carry lossless PCM audio; use 320 kbps for those.
• The MP3 is a fraction of the MOV size because the video (the bulk of the file) is discarded.
• HEVC vs H.264 video codec makes no difference here — only the audio track is used.
• Trim afterwards to isolate the part you need instead of keeping a long recording.
