How to Extract Audio from Video Online
Drop a video file into the extractor above and choose your output format: AAC (M4A), Opus (OGG), or lossless WAV. The tool decodes the video’s audio track and re-encodes it in your chosen format. Download the result. No server involved. No account needed.
Common use cases include ripping audio from interviews for transcription, pulling music from a video clip, and extracting voiceovers for reuse. If your video needs trimming first, run it through the video trimmer before extracting.
AAC vs Opus vs WAV: Which Format to Choose
AAC is the most widely supported lossy format. It plays on every phone, browser, and media player. Choose AAC when compatibility matters. Opus is a modern codec that delivers better quality at lower bitrates, but support outside of browsers and Android is more limited.
WAV is uncompressed audio. It preserves every sample from the original track, making it ideal for editing or archiving. The file will be much larger. For podcasts, social clips, and general sharing, AAC at the default bitrate is the right pick.
Why Extract Audio in the Browser?
Desktop tools like FFmpeg can do this, but they require installation and command-line knowledge. Online upload-based converters add wait times and expose your files to third-party servers. This browser-based audio extractor gives you the speed of a local tool with zero setup.
The extraction runs via WebCodecs on your hardware. Your video stays on your device throughout the process. You can also convert video formats or compress video using the same local processing engine. For caption workflows, explore Velocaption. See all tools on the tools page.
