Convert a modern Opus audio file (the codec behind WhatsApp voice notes and YouTube audio) into an MP3 that plays on any device. Opus compresses better than MP3, but hardware support is still patchy — MP3 is the universal fallback.
Opus to MP3 turns modern, ultra-efficient audio into the universally playable kind. Opus is the codec behind WhatsApp voice notes, Telegram audio and YouTube’s sound — brilliant at tiny sizes — yet a saved .opus file is nearly useless the moment you open it in an ordinary player, editor or car system. MP3 fixes that instantly.
This is the everyday rescue for a WhatsApp voice message you want to keep, edit or forward as a normal audio file. Opus packs great quality into a small file, and the MP3 preserves that quality while finally letting the clip play in any app, on any device, without hunting for special software.
Opus is the newest mainstream audio codec, designed for everything from voice calls to full music. Opus sounds better than MP3 at the same bitrate, which is why WhatsApp, Discord, and YouTube use it under the hood. The catch: most consumer hardware still cannot play .opus files directly — convert to MP3/AAC for portability.
MP3 is the most compatible audio format ever made. It plays on every device built in the last 25 years, from a $5 Bluetooth speaker to a Tesla, and 320 kbps MP3 is sonically indistinguishable from CD for most listeners. Pick MP3 when you want a file that will simply play, everywhere, without anyone asking what a codec is.
Drop a OPUS file from your device, or paste a public URL pointing to the OPUS you want to convert.
The output is pre-set to MP3.
Click Convert. Our cloud workers fetch the OPUS, scan it for malware (video and audio over 1 GB are not scanned), and run the OPUS → MP3 pipeline.
A download link appears as soon as the MP3 is ready; it works for anyone who has it until the file is deleted. The file is deleted from our storage two hours after it was made (longer for very large files or with a pass), normally within the next 15 minutes.
