This converter processes files on your device using FFmpeg compiled to WebAssembly. Your audio and video files never leave your computer. There is no upload step, no cloud processing, and no file size limit. Pick a file, choose a format, and the conversion happens right here.
The tool supports 11 output formats: MP3, WAV, M4A, OGG, FLAC, WebM, AAC, AIFF, AC3, MP2, and WMA. You can convert from almost any audio or video source, including MP4, MOV, AVI, MKV, and more. Need to pull the audio track from a video recording? Drop the video file in and select MP3 or WAV as the output.
Each output format comes with settings you can adjust. For MP3, choose between VBR and CBR encoding and set the bitrate anywhere from 64 to 320 kbps. For WAV, pick 16-bit, 24-bit, or 32-bit float depth. OGG files let you set quality on a 1 to 9 scale. FLAC offers compression levels from 0 (fastest) to 8 (smallest).
You can also normalize loudness to match platform targets: Spotify (-14 LUFS), Apple Music (-16 LUFS), YouTube (-13 LUFS), TikTok (-14 LUFS), and others. Select multiple files at once, pick your settings, and convert them all in one batch.
Traditional online converters upload your files to a remote server for processing. That creates privacy risks, especially with voice recordings, meetings, or unreleased music. This tool avoids all of that. The FFmpeg engine runs as WebAssembly inside your browser tab. Nothing is transmitted over the network. When you close the page, all temporary data is gone.
