How to convert MPG to AVI
- Add your .MPG file - drop it in the box above or click to browse.
- Convert it to .AVI in a few seconds.
- Download your new .AVI file.
What to expect
- The conversion is a re-encode, not a container swap - some quality loss is unavoidable regardless of the tool you use.
- AVI has a 2 GB file-size ceiling in its original spec; very long
.mpgfiles may need splitting if the target player is old. - MPG files sometimes carry MP2 or AC-3 audio; AVI players expect MP3, so the audio stream is automatically transcoded.
Frequently asked questions
Can I convert MPG to AVI without losing quality?
Not entirely - both formats use lossy compression and the re-encode introduces a small loss. At high-quality settings the difference is minimal, but it is not lossless.
Why does my converted AVI have no audio?
The source
.mpg may carry MP2 or AC-3 audio that the AVI container or player does not support. Re-run ffmpeg with -c:a libmp3lame to force MP3 output.Is AVI still a good format to use?
Only when a specific tool requires it. For general use, MP4 offers better compression, wider device support, and no file-size ceiling.
How long does the conversion take?
A one-hour
.mpg file typically takes 5-20 minutes on a modern CPU; enabling hardware encoding (e.g., -c:v h264_nvenc in ffmpeg) can reduce that to 1-3 minutes.
