About the formats

WAV · Waveform Audio

WAV is uncompressed audio, used for recording, editing and audio production. Files are large but lossless.

AAC · Advanced Audio Coding

AAC is the lossy audio format used by Apple, YouTube and most streaming services. It sounds better than MP3 at the same bitrate.

The conversion runs on your device using FFmpeg compiled to WebAssembly. You can adjust: bitrate, sample rate, channels, normalise loudness, start at, end at.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly. Your files never leave your device, so it is safe for private photos, contracts and business data. Once the page has loaded it even works offline.

Will converting WAV to AAC reduce quality?

AAC uses lossy compression, so some detail is traded for a smaller file. At the default quality the difference is very hard to see or hear, and you can raise the quality setting if you need more.

Can I convert multiple WAV files to AAC at once?

Yes. Add as many WAV files as you like; they are converted in parallel on your device and you can download them all as a single ZIP.

Is it free? Are there limits?

It is free, with no sign-up, no watermark and no daily limits. Because nothing is uploaded there is no upload size limit either; the only limit is your device’s memory, which matters mostly for very large videos.
