Why Convert MPEG to MP4?

MPEG-1 and MPEG-2 files are heavy for what they hold, encoded before the codecs that make modern video small and sharp arrived. MP4 with H.264 fits the same footage into a fraction of the space.

Converting also gets you a container that streams and seeks cleanly, instead of one built for VCD discs and broadcast tape.

Frequently Asked Questions

Can I convert MPEG to MP4 in the browser?
No. Legacy MPEG program streams run in the desktop app through FFmpeg. The conversion is fully local; nothing leaves your Mac.
How much smaller will the MP4 be?
Often substantially. H.264 is far more efficient than MPEG-1 and MPEG-2, so the same footage typically lands at a fraction of the original size at comparable visual quality.
Is .mpg the same as .mpeg?
Yes. They are two extensions for the same MPEG-1 or MPEG-2 stream, and both convert identically here.
Will DVD-ripped VOB-style MPEG-2 convert?
MPEG-2 program streams convert cleanly to H.264 MP4. Note that only the default audio track is kept; alternate language or commentary tracks are not carried over.
Is my file still private in the desktop app?
Yes. The desktop app converts with native engines on your Mac and works offline after a one-time activation check. Nothing is uploaded, in the browser or on desktop.

Converting a stack of legacy MPEG files?

TeraConvert Desktop converts MPEG-1 and MPEG-2 files to MP4 through native FFmpeg, batch included.
