WAV to AAC — frequently asked questions
Is this WAV to AAC converter really free?
Yes — completely free, with no sign-up, no watermarks and no daily limits.
Will I lose quality converting to AAC?
AAC uses lossy compression, so the image is re-encoded at high quality (92%). For photos the difference is practically invisible; for text-heavy graphics or logos, a lossless format like PNG preserves sharp edges better.
Is the conversion private?
Audio conversion runs on our servers with ffmpeg — your file is deleted immediately and never stored.
