About the WAV to AAC Converter
Convert WAV to AAC online for free, with no account and no watermark. WAV files are huge, around 10 MB per minute of audio, so switching to AAC is the quickest way to get compact AAC audio for streaming, YouTube uploads, Apple devices and smaller music files.
Audio and video are processed by FFmpeg compiled to WebAssembly, the same open-source engine behind VLC and HandBrake, running inside your browser tab. Because everything happens on your own device, your audio files are never uploaded, stored or seen by anyone else, which makes it safe for voice recordings, interviews and unreleased music.
What to expect: the sample rate and channels are kept, and you can pick the bitrate; the processing engine (about 30 MB) is downloaded once and then cached by your browser.
How to use the WAV to AAC Converter
- Click "Choose files" or drag your WAV audio files onto the box. You can add several at once.
- Choose the AAC bitrate: 128 kbps for speech, 192 kbps for music or 320 kbps for the best quality.
- Press "Convert to AAC". The conversion runs on your device and shows its progress.
- Download each AAC file, or use "Download all (ZIP)" when you converted several.
- Open the result in VLC or iTunes to check it; your original WAV is never changed.
Tips & benchmarks
- The raw .aac stream is widely playable; choose M4A instead if you need tags and cover art.
- WAV is lossless and AAC is not, so keep your original WAV as the master copy and use the AAC for sharing.
- As a guide, one minute of audio at 128 kbps is about 1 MB, and at 320 kbps about 2.4 MB.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the AAC to a website or government portal.
