Convert MPEG to MP4 Online — No Upload, No Watermark
MPEG is the umbrella container for older MPEG-1 and MPEG-2 video — best converted to MP4 for modern playback. Converting to MP4 gives you a file that plays on every phone, browser, and editor without re-encoding at playback time.

Where MPEG files come from
MPEG and MPG files hold MPEG-1 or MPEG-2 video, the standards behind Video CD, DVD and digital broadcast television. They arrive from DVD rips, TV capture cards, and any device that recorded to disc.
What changes when you convert MPEG 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 for the same picture |
Worth knowing first
MPEG-2 is roughly four times less efficient than H.264, so these files are enormous for what they show. Broadcast and DVD sources are also usually interlaced, which looks like comb-shaped tearing on fast motion when played on a computer. This conversion does not deinterlace; if you see combing, run the clip through the Video Filters tool afterwards.
FAQ
Why is my DVD rip several gigabytes for one film?
DVD video is MPEG-2, a standard from 1995 that needs about four times the bitrate of H.264 for the same picture. Converting typically cuts the file to a quarter or a fifth of its size with no visible difference, because the inefficiency is in the old codec rather than the content.
The picture has horizontal comb lines on movement. Why?
The source is interlaced, as broadcast and DVD video almost always are. Each frame holds two fields captured at different moments, which a progressive screen shows as combing. The conversion preserves the frames as they are, so the combing carries over. Deinterlacing is a separate step.
Is MPG different from MPEG?
No, they are the same thing with different extensions, a leftover from the days of three-character filenames. Both convert identically here.
Is this MPEG to MP4 converter really free and without upload?
Yes. The tool runs entirely in your browser using FFmpeg compiled to WebAssembly. Your MPEG 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.
