About audio file conversion

Audio conversion changes the container or codec of a sound file (for example WAV to MP3 or FLAC to AAC). This can dramatically reduce size, improve device compatibility, and prepare clips for streaming or editing.

Popular audio conversions

• WAV to MP3 – compress large recordings for sharing.
• FLAC to MP3 – create smaller, widely supported files.
• MP3 to WAV – export for editing or DAWs.
• M4A to MP3 – improve cross‑platform playback.
• OGG to MP3 – re‑encode for broader support.
