Convert MPG to MP4 Online — No Upload, No Watermark
MPG (MPEG-1/2 Program Stream) is a legacy DVD-era container — most modern players need conversion. Converting to MP4 gives you a file that plays on every phone, browser, and editor without re-encoding at playback time.

Where MPG files come from
MPG is the short-extension spelling of MPEG, holding MPEG-1 or MPEG-2 video. It turns up in DVD rips, TV capture, and files written by older camcorders and set-top recorders.
What changes when you convert MPG to MP4
| Video | MPEG-1 or MPEG-2 re-encoded to H.264 |
|---|---|
| Audio | MP2 or AC-3 re-encoded to AAC |
| File size | Typically shrinks by 60 to 80 percent |
Worth knowing first
These files are often interlaced and frequently carry a 4:3 aspect flag that modern players ignore, so the picture can come out stretched. Check the result, and if the shape is wrong the Video Resizer can force the correct aspect.
FAQ
Why does my converted MPG look stretched?
Old MPEG files store a display aspect ratio separately from the pixel dimensions, because standard-definition video used non-square pixels. Some players honour the flag and some do not. If the result looks wrong, set the intended aspect explicitly with the Video Resizer.
Can I keep the original quality exactly?
Not while changing codec, since H.264 and MPEG-2 compress differently. CRF 23 keeps the loss well below what is visible on this kind of source, which was rarely sharp to begin with.
Will the conversion fix stuttering playback?
Usually. Stutter on MPEG files is often the player struggling with the old codec or with broken timestamps in the stream. The converted file has clean timestamps and a codec every device decodes in hardware.
Is this MPG to MP4 converter really free and without upload?
Yes. The tool runs entirely in your browser using FFmpeg compiled to WebAssembly. Your MPG file never leaves your device — open the DevTools Network tab to verify zero uploads. No signup and no watermark. The practical size limit is the memory your browser gives this tab, which is generous on a computer and a few hundred megabytes on a phone.
