How to Extract Audio from Video
-
Upload Your Video File
Drag and drop your video file into the upload area or click to browse your device. The converter accepts MP4, WebM, MKV, and MOV formats up to 500MB in size. -
Choose Your Output Format
Select the audio output format you prefer. WAV is always listed because it is lossless PCM, while MP3, OGG, FLAC, and AAC appear only when your browser can encode them. Set an optional start and end time if you want one section rather than the whole track. -
Extract the Audio Track
Click the Extract Audio button to start processing. The tool reads the audio track out of your video with WebCodecs through the Mediabunny library and writes it in the format you chose. The video file does not leave your device, and there is no playback while it works. -
Download Your Audio File
Once extraction is complete, preview the audio output to verify quality. Click Download to save the audio file to your device. You can then use an audio format converter or audio trimmer to further edit the result.

Why use our Video to Audio Converter?
The Video to Audio Converter is a browser-based tool that extracts audio tracks from video files without uploading anything to a server. Whether you need to pull a soundtrack from an MP4, rip dialogue from a recorded meeting, or save a voiceover from a tutorial video, this tool handles it in seconds. It supports MP4, MOV, WebM, and MKV input, always offers WAV output because that is the one format every browser can write, and adds MP3, OGG, FLAC, or AAC when your browser can encode them.
Unlike server-based converters that require you to upload sensitive files, this tool reads the audio track locally with WebCodecs through the Mediabunny library. Your video file never leaves your device, which suits confidential recordings, private meetings, and anything you would rather not store on third-party infrastructure. Files up to 500 MB are accepted, there is no signup, and there is no watermark on the output. If you need to convert the extracted audio to a different format afterward, use the Audio Format Converter. For trimming the result, the Audio Trimmer lets you cut specific sections. You can also convert videos between formats using the Video Format Converter or create animated previews with the Video to GIF converter.
This tool is particularly useful for content creators who repurpose video into audio-only formats, students extracting lecture audio for revision, and anyone who wants to separate a music track from a video recording. Combined with other FindUtils media tools, you have a complete browser-based workflow for video and audio processing without installing any software.
How it compares
Most online video-to-audio converters require you to upload your file to a remote server, wait for processing, and then download the result. This raises privacy concerns and adds unnecessary wait time, especially for large files. Server-based tools like CloudConvert and Online-Convert offer broad format support but require accounts for larger files and process your data on their infrastructure.
The FindUtils Video to Audio Converter runs entirely in your browser. There is no upload step, no account creation, and no file size queue. Extraction begins as soon as you click and runs faster than real time, because the data never travels over the network. The trade-off is that output format options depend on browser codec support: WAV is always there, while MP3, OGG, FLAC, and AAC appear only when your browser can encode them. For the common case of pulling audio out of an MP4 or WebM, that is more than enough, and there is no privacy risk.
Tips for Best Results
- Use high-quality source videos for better audio output. The extracted audio can only be as good as the original recording.
- Preview the video before extracting to make sure it contains the audio track you need. Some screen recordings may have no audio.
- For large video files, ensure your browser tab stays active during processing. Switching tabs may slow down extraction.
- If you need MP3 specifically, choose it in the output picker. It is listed only when your browser can encode MP3; otherwise pick WAV, which every browser can write.
- Set the start and end time before extracting to keep only the section you need, or trim the result afterwards with the Audio Trimmer.
