About MPEG
MPEG files (.mpg, .mpeg) are MPEG-1 or MPEG-2 program streams, the standards behind Video CD and DVD video.
Older camcorders, DVD-era video files and broadcast archives.
MPEG-1 and MPEG-2 compress far less efficiently than H.264, so the files are large for their quality.
Convert MPEG to Opus online free, no account required — Opus is a modern open lossy codec for speech and music.

Why does my MPEG video look soft on a modern screen? MPEG-1 and MPEG-2 were designed for VCD and DVD resolution, so upscaling a 576-line picture to 4K shows every limitation of the era.
About Opus
Opus is an open, royalty-free lossy audio codec standardised by the IETF in 2012 (RFC 6716). It handles both speech and music well, from very low to high bitrates.
Voice and video calls, WhatsApp voice messages, WebRTC, and the audio track of WebM videos.
Opus always decodes at 48 kHz, and some older players and devices do not support it.
Why convert voice recordings to Opus? It stays clear at very low bitrates, so calls and dictation shrink dramatically without becoming hard to understand.
What changes when you convert MPEG to Opus
- The soundtrack of the MPEG is re-encoded as Opus at the default settings, so it is close to the original but not bit-identical.
- Only the sound is kept: the Opus file contains the audio track of your MPEG, and the picture is dropped.
Settings you can change
