Convert WAV to AAC Free

The catch with most "free" converters shows up at the end: the download needs an account, a watermark tone is mixed into the audio, or your file waits in a queue behind paying users. None of that applies here. The engine is the same one Pro uses — same speed, same bitrate options — and the output is clean and unmarked.

Free also means free of the usual hidden cost: your file. Many no-cost converters are free precisely because your upload is the product. Here the conversion runs in your browser, so the WAV never leaves your device. Given that WAV files usually come from recording sessions, DAW bounces, and anything captured uncompressed, that's worth more than the price.

WAV costs you around 10 MB for every minute; AAC asks for about 1.2. Over a long recording that gap is the whole reason to convert. Starting from WAV means the encoder isn't working around someone else's compression. That's why this produces a better AAC than converting from an already-lossy file would.

Free covers input files up to 20MB file size limit with a 10-second preview output, and 5 conversions per month. Pro removes those limits for full-length conversions up to 500MB file size limit — and the privacy behaviour is identical, because there was never a server in the loop.

Most people meet WAV through recording sessions. It is a fine format there; the trouble is that WAV is uncompressed, so files are enormous — an hour of audio runs past 600 MB. AAC is the destination because it plays essentially everywhere — HLS streaming segments and every ordinary phone, browser, and player. WAV costs you around 10 MB for every minute; AAC asks for about 1.2. Over a long recording that gap is the whole reason to convert. Because WAV is uncompressed, encoding to AAC here is the clean, single-generation case — the encoder sees the whole original signal, so this AAC is as good as the format gets.
