Frequently asked questions

What is an Opus file and why convert it?

Opus is an efficient audio format used by voice chat apps and web audio, usually inside an .opus or .ogg file. Many players, editors and older devices can't open it, so converting to MP3 makes it work everywhere.

Will I lose quality?

Opus and MP3 are both lossy formats, so converting re-encodes the audio. At 192 kbps or higher the difference is hard to hear for speech and most music. Choose WAV to avoid adding any further loss.

Are my files uploaded anywhere?

No. Opus to MP3 runs entirely in your browser. Your files are processed on your device and are never sent to a server.

Is there a file size limit?

No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.

Is Opus to MP3 really free?

Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.

Does it work offline?

Once the page has loaded, processing happens locally, so it keeps working even if your connection drops.
