    What is an Online Audio Extractor?

    Want to save just the background music from a movie, lecture content, or catchy dialogue as an audio file? This powerful, free Online Audio Extractor is the tool you’re looking for! Not only can it quickly and easily extract pure, independent audio files from videos, but it can also convert them into multiple formats. These include high-quality WAV, FLAC (lossless), compressed formats like MP3, M4A, WebM, OGG, and even the iPhone Ringtone format M4R! If you don’t need conversion, it can also export the video’s inherent audio track exactly as is.

    Why Choose this Audio Extractor?

    • Extract Multiple Audio Tracks: Easily separate multiple audio tracks within a video (like narration and background music), getting multiple audio files at once!
    • Privacy & Security: Processing happens entirely in your browser! Your video file is never uploaded to any server, meaning your privacy is maximally protected. Processing is faster because it eliminates upload and download waits. It also saves a tremendous amount of network bandwidth.
