How do I convert an AAC file to OPUS?

Upload your AAC file to LetsConvert, choose OPUS as the target format. Optionally select a bitrate (e.g., 128 kbps for music, 64 kbps for voice). Click Convert, wait for the encoding to finish, then download your OPUS file. No software installation is required.

Why should I convert AAC to OPUS instead of keeping AAC?

OPUS offers better compression efficiency than AAC, meaning smaller file sizes for the same perceived quality. It is particularly strong for voice content and is widely supported in web browsers, Discord, and many modern players. However, AAC is still preferred for Apple devices and some hardware players due to native support. Convert when you need to save space or improve streaming performance.

What happens to the audio quality and metadata during AAC to OPUS conversion?

Converting from AAC to OPUS is a lossy re-encode, so there is generational loss. The decoder reconstructs the PCM signal, which is then encoded in OPUS. The tool preserves sample rate, channel count, and bit depth where possible, and you can set the bitrate. OPUS typically handles 48 kHz audio with variable bitrate; metadata like tags and cover art are copied when present in the AAC container. For archival purposes, consider keeping the original lossless file.

Is AAC-TO-OPUS free to use?

Yes, AAC-TO-OPUS on LetsConvert is 100% free with no registration or hidden fees required.
