AVI to MP3
Pull the audio track out of an AVI file and save it as a high-quality VBR MP3 (around 190 kbps, ffmpeg quality 2). The video stream is discarded — this is the right tool when you want a podcast, lecture, music clip, or voice memo extracted from an older AVI capture, an archived DVD rip, or any legacy video file. The conversion runs locally via ffmpeg.wasm, so your file never leaves your device. AVI containers often hold older codecs (MP3, AC3, or PCM audio) — all decode fine in the browser, but very long or high-resolution sources may still take a while.
