What is AAC?
AAC is the successor to MP3: better quality at the same bitrate, and the default for Apple, YouTube and most streaming.
What is Opus?
Opus is a modern open codec that beats MP3 and AAC at low bitrates, which is why it powers most voice chat and is excellent for speech and music alike.
Why convert AAC to Opus?
Most people convert AAC to Opus for compatibility — a website, app or device insists on Opus, and AAC simply won't open. Opus is widely supported, which makes it a dependable target. Audio is processed with ffmpeg using high-quality encoders (LAME, libopus, libvorbis, FLAC and more), so you get the best possible result for the destination format.
When you'd convert AAC to Opus
Typical uses: preparing assets for a website, attaching a file someone else can definitely open, or standardising a folder of mixed files into one format.
Is it private?
Privacy is the default here. Your AAC file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
