Free Video to MP3 Converter - Extract Audio Online

A 128 kbps for speech, 192 kbps for music, 320 kbps for maximum quality.

A You need to first download the video file, then use this tool.

A This unique video to MP3 converter processes your files directly within your browser, eliminating the need to upload them to a server. Your video never leaves your device, ensuring maximum privacy and security for your content. This method also results in significantly faster conversion times, as it avoids delays associated with large file transfers over the internet. You simply select your video, choose the bitrate, and the audio is extracted locally.

A This free online Video to MP3 tool extracts the complete audio track from your selected video file. It does not currently offer a built-in feature to trim or select specific audio segments. If you only need a particular portion of the audio, we recommend using a separate video editor to first trim your video to the desired length before processing it with our converter. This ensures you get the exact audio clip you need for your projects or social media content.

A Not at all. This tool focuses solely on the audio track. The video quality itself is irrelevant to the MP3 extraction process. You select the bitrate for the audio, not the video, so the original video's resolution or frame rate won't be affected. Pick a higher bitrate, like 320 kbps, for the best possible audio fidelity from your video.

A No hard file size limit exists since processing happens locally on your device. Your browser's memory capacity is the real constraint. Most modern browsers handle videos up to 2GB without issues. Older computers might struggle with files over 500MB. Try closing other browser tabs if you hit performance problems.

A Yes, it runs on any device with a modern browser — phones, tablets, laptops. Since everything processes locally, you don't need a powerful computer. I've tested it on an iPhone 12 and a Samsung Galaxy S21 without issues. Just make sure your browser is up to date. Older browsers might not support the required WebAssembly technology.

A Your original video file stays completely untouched. This tool reads the video to extract audio, but never writes to or modifies the source file. You'll end up with a new MP3 file while keeping your original video exactly as it was. Think of it like photocopying a page — the original stays perfect. I've tested this with dozens of files, including RAW footage from a Sony A7 III, and never had an issue. For extra safety, store your original video in a separate folder before running the conversion.

A Yes, once the page finishes loading in your browser, the entire conversion engine runs locally on your device. You can disconnect from the internet after that and still convert videos to MP3. The tool loads about 3MB of WebAssembly code upfront. This makes it perfect for editing in places with spotty WiFi — trains, planes, or coffee shops with bad connections. Just refresh the page if you want to use it again later.

A That depends entirely on what you do with the resulting MP3 file. Extracting audio for personal use — like turning a lecture recording into a study playlist — is generally fine. But pulling music from a copyrighted video and sharing it publicly? That's a clear violation. Always check the video's license or creator permissions before saving the audio. I'd suggest sticking to content you own or that's explicitly marked for reuse under Creative Commons.
