Frequently Asked Questions - OPUS to MP3
What is OPUS and where is it used?
OPUS is a modern audio format commonly used by messaging apps for voice notes and voice chat, as well as VoIP applications. It offers excellent quality at low bitrates, but not all players support it.
Why convert OPUS to MP3?
While OPUS is technically superior, MP3 is universal. If you want to listen to your voice messages on an old MP3 player, car audio system, or edit the audio in traditional software, you need to convert to MP3.
Do I lose quality converting OPUS to MP3?
Depends on the original bitrate. Voice message OPUS is typically 16-32 kbps, while our MP3 options range from 128-320 kbps. In this case, you actually gain clarity. For high-quality OPUS music, there's minimal to no quality loss, especially at higher MP3 bitrates.
How do I convert Telegram voice notes?
Export the voice note from Telegram to your device (message options → Save). The file will be .ogg or .opus. Then upload it here and we'll convert it to MP3 without sending it to any server.
Does it work with Discord audio?
Yes, Discord uses OPUS for its voice chat. If you recorded or downloaded audio from Discord, it's probably in OPUS format. Converting it to MP3 makes it compatible with all players.
Why are Telegram and WhatsApp voice notes in OPUS?
OPUS excels at low-bitrate voice compression—a 1-minute voice note is only ~200 KB while maintaining clear speech. It's perfect for messaging apps where millions of voice messages are sent daily. MP3 would use 3-5x more bandwidth for the same voice quality.
