An audio extractor is a tool that separates the audio track from a video file, saving it as a standalone audio file you can play anywhere. Every video file contains at least one audio stream multiplexed alongside the video stream. Extraction pulls out that audio data without re-encoding the video, making the process fast and lossless when using compatible formats.
Our browser-based extractor uses FFmpeg compiled to WebAssembly, giving you desktop-quality audio extraction without installing any software. Your files never leave your device — the entire conversion runs locally in your browser using your computer's processing power.
Extracting audio from a video takes three simple steps. First, upload your video file by dragging it into the upload area or clicking to browse. The tool accepts MP4, MOV, WebM, AVI, and MKV files. Second, choose your output format and quality settings. MP3 at 192 kbps is the recommended default for most uses — it offers excellent audio quality at a reasonable file size. Third, click Extract Audio and wait for the processing to complete. You can preview the result with the built-in audio player before downloading.
If you only need a portion of the audio, enable the trim option before extracting. Set your start and end times using the text inputs or drag the range slider. Only the selected section will be processed, saving time and producing a smaller file.
MP3 is the universal audio format with 99% device compatibility. It uses lossy compression to reduce file sizes dramatically — a 4-minute song at 192 kbps is roughly 5.5 MB compared to 40 MB for the same audio in WAV. At 192 kbps or higher, most listeners cannot distinguish MP3 from the original audio. Choose MP3 when you need maximum compatibility and reasonable file sizes.
WAV stores uncompressed, lossless audio at CD quality (16-bit, 44.1 kHz). Files are significantly larger — about 10 MB per minute of stereo audio — but there is zero quality loss. Choose WAV when you need the highest possible quality for professional audio editing, music production, or archival purposes.
AAC (Advanced Audio Coding) is the successor to MP3 and offers better sound quality at the same bitrate. It is the default audio format for Apple devices, YouTube, and most streaming services. At 128 kbps, AAC sounds roughly equivalent to MP3 at 160 kbps. Choose AAC for Apple ecosystem compatibility or when you want better quality at lower bitrates.
OGG Vorbis is an open-source format that provides excellent quality at low bitrates without any licensing restrictions. It is supported by Firefox, Chrome, Android, and most media players. At 192 kbps, OGG Vorbis is perceptually transparent for most content. Choose OGG when you prefer open formats or need good quality with small file sizes.
Podcast creation: With over 4 million active podcasts worldwide, many creators extract audio from video recordings to publish as podcast episodes. Record your video interview or presentation, then extract the audio track for your podcast feed. This workflow lets you publish on both YouTube and podcast platforms from a single recording.
Music from videos: Extract audio from concert recordings, music videos, or live performances to listen on the go. Converting to MP3 at 256 or 320 kbps preserves excellent music quality while keeping file sizes manageable for portable devices.
Lecture and meeting notes: Extract audio from recorded lectures, webinars, or meetings to create audio-only versions you can review during commutes or workouts. A one-hour meeting video at 192 kbps MP3 is only about 86 MB — easily stored on any device.
Ringtones and sound effects: Use the trim feature to cut specific moments from videos — a memorable quote, a sound effect, or a music clip. Extract just the section you need and save it as a compact MP3 file ready to use as a notification sound or ringtone.
Language learning: Extract dialogue from foreign-language videos or movies to create audio-only practice files. Listening repeatedly to extracted audio helps build vocabulary and improve pronunciation without the distraction of visuals.
