How this works
This tool uses ffmpeg.wasm to run FFmpeg in the browser. It re-encodes the audio using the specified bitrate (for lossy formats) or lossless compression (for FLAC). All processing happens locally no upload to a server.
Common uses
Shrinking voice memos for email, reducing music file size for mobile devices, or preparing audio for web uploads with size limits.
