What changes
Both formats are lossy. Converting decodes the file and compresses it again, so it loses a little more detail on top of what the original had already lost: the result is slightly worse than the file you started with.
The file size stays about the same.
When it’s worth it
Choose MP4 for: Phones, websites, social networks, and TV. Small files for the quality, usually with H.264 or H.265 inside.
Stay with MPG for: Older video players and archives.

Questions
Does converting MPG to MP4 lose quality?
A little. Both formats are lossy, so the file is compressed again and loses a bit more detail.
What is the MP4 format?
A container that holds a video track, one or more audio tracks and metadata, and nothing else: which codec sits inside is a separate question. H.264 or H.265 video with AAC audio is the combination almost everyone means by MP4.
What is the MPG format?
The same MPEG-1 or MPEG-2 video as .mpeg, under an extension that is simply shorter. Nothing in the file changes, but some older software only recognizes the video when the name ends in .mpg.
Are the files uploaded?
No. The file is opened in this tab, converted here and saved from here. There’s no account and no watermark.
How many files can be converted at once?
Up to 200 per batch and about 2 GB per file, within the memory this device has available.
