Pull the soundtrack, background music, or dialogue out of any video file. It's incredibly fast because your video never leaves your computer.
Select Your Video

Choose Audio Format
Select whether you want to save the extracted sound as a standard MP3, an M4A for Apple devices, or a lossless WAV file.
Extract & Download
Click extract. Our local WebAssembly engine strips out the heavy video layers entirely and exports a clean audio file for you to download.
Benefits of Our Video to Audio Converter
No Upload Wait Times
Video files are huge. Waiting to upload a 200MB video file to a remote server just to get a 3MB MP3 is frustrating. By extracting locally, you skip the upload entirely.
100% Private Processing
Your personal videos, family clips, or unreleased music videos never leave your device. We use WebAssembly to extract the audio strictly within your browser's secure sandbox.
Supports Major Video Codecs
Whether you recorded a video on an iPhone (.mov), downloaded it from the web (.mp4), or exported it from a video editor (.mkv), our tool can isolate and extract its audio track.
High Quality Audio Export
When saving as a compressed format like MP3, we default to a high-quality 192kbps bitrate. If you choose WAV, the extraction is fully uncompressed and lossless.
Frequently Asked Questions
No, absolutely not. The tool simply creates a copy of the audio track and provides it to you as a separate download. Your original video file remains untouched on your hard drive or phone.
We recommend uploading video files under 200MB. Because the extraction process happens entirely inside your browser's local RAM (memory), attempting to process massive multi-gigabyte 4K videos may cause your browser tab to crash.
Yes, it is 100% private. Unlike traditional cloud converters, we never upload your heavy video files to a remote server. The WebAssembly engine isolates the audio locally on your machine.
Our audio visualizer (WaveSurfer) is capable of reading the audio channel hidden inside your video file instantly. This allows you to preview the sound and verify you uploaded the right video before you even click extract.
