Convert MPG to MP4
Video from a DVD rip, an old camcorder or a broadcast archive is an MPG file that phones will not play.

Where the streams already fit the target container this is a lossless remux, which is close to instant. Otherwise it re-encodes, which in a browser is slow — keep it under a few hundred MB and send long videos to the cloud engine.

What actually changes
MPG and MP4 are not the same picture in two wrappers.
MPEG-1 or MPEG-2 video is re-encoded to H.264, typically cutting the file to a quarter of its size at the same visual quality, and the MP2 or AC-3 audio becomes AAC.
Worth knowing first
MPEG-2 from DVD sources is interlaced, and if you convert without deinterlacing, every frame with motion in it shows comb-shaped tearing on a progressive screen. That artefact is introduced by skipping a step, not by the codec.
Questions
MPG to MP4, answered
What is deinterlacing?
Old broadcast video stored two half-resolution fields per frame. Deinterlacing recombines them into whole progressive frames for modern displays.
How much smaller will the file be?
Commonly 60 to 75 percent, because H.264 is two codec generations ahead of MPEG-2.

MPEG-4 Video is lossy, so the quality control decides the trade between size and fidelity.

Instant, because the file never went anywhere. Nothing expires, since nothing was stored.
