Extract Audio From Video to MP3 — Free, Fast, No Signup
Got a lecture recording, podcast, or music video but want just the audio? Extract to MP3 in your browser — no upload, no signup, no watermark.
Audio extraction is one of the most-searched conversion tasks. Reasons vary: saving lecture recordings to listen on commute, ripping podcast audio from YouTube interviews, pulling music from concert footage, archiving voice notes from video calls. Browser-based extraction keeps your videos (which often contain private content) entirely on your device.
Open MP4 to MP3 ConverterStep-by-step
Open the MP4 to MP3 tool
Click below to launch. Works with MP4, MOV, WebM, AVI, and most other video formats.
Drop your video in
Drag and drop, or click to browse. The tool reads the video locally — your file never uploads anywhere. Bigger videos may take a few seconds to load.
Choose audio quality
192kbps is a great balance — clean audio without a huge file. 128kbps is fine for spoken content (lectures, podcasts). 320kbps for music if you want maximum quality.
Download the MP3
Extraction usually takes 10-30 seconds depending on video length. You get a clean MP3 file with just the audio — no video, no metadata you didn't ask for.

Open MP4 to MP3 ConverterFrequently asked questions
Can I extract audio from any video format?
Most common formats yes — MP4, MOV, WebM, AVI, MKV, FLV. The tool auto-detects the format. If a specific file doesn't work, it's usually because it uses an exotic codec; converting it to MP4 first with a video converter will fix this.
Will the extraction lose audio quality?
Minimal loss. The audio inside videos is already compressed (usually AAC or MP3). Extracting and re-encoding to MP3 at 192kbps+ preserves the audio quality as well as possible. Pick a higher bitrate for music, lower for voice.
Is this legal?
Depends on the source. Your own recordings, public domain content, and Creative Commons content — fully legal. Copyrighted videos (e.g. ripping a song from someone else's YouTube video for commercial use) — that's copyright infringement. Personal use is a gray area; consult your local laws.
How long can the video be?
Limited by your device's memory. Most modern phones and laptops can handle videos up to several hours. For very long videos (3+ hours), you may want to split the video first to avoid running out of memory.
