The WAV to AAC Converter transforms uncompressed WAV audio files into compact AAC format. AAC delivers excellent audio quality at significantly smaller file sizes and is the default format for Apple devices, YouTube, and modern streaming platforms. All conversion happens in your browser.
This tool uses the Web Audio API to read your WAV file and encode it as AAC using the browser's WebCodecs API. Starting from uncompressed WAV gives you the highest quality AAC output with no prior compression artifacts. AAC is the successor to MP3 and offers better quality at equivalent bitrates.

Does converting WAV to AAC lose quality?
Yes. AAC is a lossy format, so some audio quality is lost. However, converting from uncompressed WAV ensures the loss is only from that single encoding step, giving you the best possible AAC output.
Is AAC better than MP3?
Yes. AAC generally delivers better audio quality than MP3 at the same bitrate and is natively supported on Apple devices and most streaming services.
Are my files uploaded to a server?
No. All conversion happens in your browser using the Web Audio API. Your files never leave your device.
What browsers support AAC encoding?
AAC encoding requires a Chromium-based browser like Google Chrome or Microsoft Edge. Firefox does not currently support AAC encoding.
Should I keep my WAV files after converting?
Yes. Keep WAV files as your lossless masters. The AAC files are for distribution and playback convenience.
Can I convert multiple files at once?
This tool converts one file at a time. Process each file individually for batch needs.
