Frequently Asked Questions
- What formats are supported?
- We support most common video formats including MP4, MOV, AVI, and WebM.
- Is there a limit on video length?
- There is no hard limit, but longer videos will take more time to process and consume more browser memory.
- Can I extract audio from an MP4 video?
- Yes. MP4 is the most common input format. The tool strips the video stream and saves the audio track as an MP3 file directly in your browser.
- What is the difference between Audio Extractor and Video to MP3?
- Both produce an MP3 from a video. Audio Extractor focuses on outputting the raw audio track in its original quality, while Video to MP3 may offer additional bitrate options. Either tool works for most use cases.
- Does extracting audio from a video reduce its quality?
- If the source video contains an MP3 or AAC audio stream, the extractor can copy it without re-encoding (no quality loss). When re-encoding is required, quality depends on the chosen bitrate — 192 kbps or higher is recommended for music.
- What output audio quality can I choose when extracting?
- When extracting audio you can choose between several bitrate presets — typically 128 kbps, 192 kbps, and 320 kbps for MP3, or lossless for WAV and FLAC output. Higher bitrates produce larger files but better audio fidelity. For music or podcasts 192 kbps is usually sufficient; for archiving original recordings choose lossless WAV or FLAC. The extraction runs entirely in your browser via FFmpeg WebAssembly so no video is uploaded to a server.
Local processing
Our local file, text and chart tools process content on your device using JavaScript, browser APIs and, where needed, WebAssembly. Our usage events do not include filenames, file contents, input text, chart values, raw errors, emails or license references. Network lookup tools (such as DNS, WHOIS, IP and speed tests) contact external services for their stated purpose. Loading the website, fonts, libraries and models also makes network requests. WebAssembly itself does not prevent network access.
