AudioExtractor – Video to MP3

Extract and download audio from video files entirely inside your browser. No uploads, no servers — 100% private.

⚠️ Browser Note: This tool works for video formats your browser can natively decode (MP4/H.264 + AAC, WebM/VP8 + Opus). Large files (>200MB) may be slow due to in-browser MP3 encoding. For best results use MP4 files.

🔒 Why no upload?

Most online converters upload your video to their servers for processing. This raises privacy concerns — your files could be stored, analyzed, or monetized. Our tool processes everything locally using the Web Audio API and LameJS encoder, so your video never leaves your device.

🎚️ MP3 vs WAV — Which to choose?

MP3 is a compressed format — smaller file size, perfect for podcasts, music, and general use. Quality is adjustable via bitrate (128kbps is standard, 320kbps is near-lossless).

WAV is uncompressed — much larger file, but perfect lossless quality for professional audio editing.
