Audio Format Converter

It depends on the output format. WAV and FLAC are lossless — quality is fully preserved. Lossy formats like MP3, AAC, and OGG will compress quality based on the bitrate setting. Higher bitrate means better quality. 128kbps and above is generally recommended for good listening quality.

Supports MP3, WAV, FLAC, AAC, OGG, M4A, Opus, WMA, AIFF and more. You can also extract audio from video files such as MP4 and MKV.

The tool supports files up to 500MB. Since conversion is done locally in the browser, the actual limit depends on your device's available memory. For large files, a PC is recommended.

No. This tool uses FFmpeg.wasm to convert audio entirely in your browser. Your files never leave your device, ensuring complete privacy.

General guidance: 128 kbps for everyday listening; 192 kbps for better quality; 256–320 kbps for high quality. FLAC/WAV lossless formats don't require a bitrate setting.

Keep the original sample rate in most cases. 44100 Hz (CD standard) is for music; 48000 Hz is for video audio. Select 'Keep Original' unless you have a specific requirement.

MP3: highest compatibility, works everywhere; AAC: better quality than MP3 at same bitrate, common in Apple ecosystem; FLAC: lossless, full quality preserved; WAV: uncompressed PCM, largest size; OGG: open-source, great for web/games; M4A: iTunes container; Opus: best quality at low bitrates.
