AAC is already selected as the output. Pick a bitrate — 320 kbps for best quality, 192 or 128 kbps for smaller files.

3. Convert & download

Click Convert & Download. Your AAC file downloads automatically, ready for iPhone, iPad, and everyday listening.

Why convert WAV to AAC?

WAV is uncompressed, so files are large. AAC compresses that audio to a fraction of the size while staying transparent at higher bitrates — ideal for phones, streaming, and Apple devices. Because you start from a lossless source, the AAC will sound as good as the codec allows at your chosen bitrate.

Which bitrate should I choose?

320 kbps for the best quality, 192 kbps for a good size/quality balance, or 128 kbps for the smallest files. Encoding from lossless WAV gives the best possible AAC. For background, see AAC vs FLAC.

Frequently Asked Questions

How do I convert WAV to AAC?

Upload your .wav file, choose AAC and a bitrate, then click Convert & Download. The AAC file is created and downloaded automatically.

Will the AAC sound as good as the WAV?

At a high bitrate like 320 kbps, AAC is transparent for almost all listeners — very close to the WAV at a fraction of the size. AAC is lossy, so it isn't a bit-perfect copy.

How much smaller will the file be?

A lot. AAC is typically several times smaller than uncompressed WAV, depending on the bitrate you choose.

Is the WAV to AAC converter free?

Yes — it's completely free, with no account, no watermarks, and no limit on how many files you convert.
