What is MP3?
MP3 is the most universally compatible audio format ever made — lossy, small, and playable on absolutely everything. The safe default when you just need audio that works anywhere.
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 MP3 to Opus?
The usual reason to convert MP3 to Opus is file size or quality: Opus fits the job better, whether that means a smaller download, a cleaner edit, or broader support. 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 MP3 to Opus
You might be optimising images for a faster-loading page, exporting for a specific app or marketplace, or just making sure a colleague on a different device can open what you send.
Is it private?
Privacy is the default here. Your MP3 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.
