Convert MPEG to MP4
Updated Jul 2026
MPEG is an older video format built for broadcast and DVDs, and MP4 is the format phones, browsers, and streaming apps expect today. To convert MPEG to MP4, open the file in a converter and export it as MP4. Doing it on your own computer keeps the video off other people's servers while you convert.

How to convert MPEG to MP4
- Open Morphjet and drag in the MPEG file you want to convert, or a whole folder of them at once.
- Choose MP4 as the output format.
- Convert. The MP4 is written next to your original, and nothing leaves your machine.
MPEG vs MP4: what actually changes
| MPEG | MP4 | |
|---|---|---|
| File size | Large, older compression from the broadcast and DVD era | Smaller, modern compression fits the same video in less space |
| Plays on phones and browsers | Rarely, without extra software | Yes, universal support |
| Quality | Fine for its era, but an older, less efficient codec | Very good, though re-encoding an already-lossy MPEG adds a small extra loss |
| Editing software support | Rarely recognized by current video editors | Supported by nearly all editors and apps |
| Uploading to streaming or social sites | Often rejected or requires conversion first | Accepted by every major platform |
When to convert, and when not to
Convert MPEG to MP4 when you want to play an old DVD-era recording or camcorder file on a modern phone or laptop, upload it somewhere, or edit it in current video software that no longer opens MPEG.
Keep the original MPEG if it's the only master copy of that recording you have, since converting one lossy format into another loses a little quality you can't get back.
Why not just use an online converter?
Old MPEG files are often family videos or home movies, sometimes the only copy that exists. Uploading one to a website converter means that footage sits on a server you don't control until someone deletes it. Converting on your own computer keeps the video, and everything in it, on your machine the whole time.
Questions
Does converting MPEG to MP4 lose quality?
A little. MPEG is already a lossy format, so re-encoding it to MP4 adds a small extra loss on top of what's already there. It's usually not noticeable for playback, but it isn't a lossless conversion either.
Will the MP4 be smaller than the original MPEG?
Usually, yes. MP4 uses newer, more efficient compression, so the same footage often takes up noticeably less space, even with a similar quality setting.
Can I play MPEG files on my phone?
Not reliably. Most phones and modern browsers were built around MP4 and similar formats, and don't include support for the older codecs MPEG files often use. Converting to MP4 fixes that.
Does the audio stay in sync after converting?
Yes. Converting re-encodes the video and audio tracks together, so sync is preserved.
Can I convert MPEG to MP4 without uploading the file anywhere?
Yes. Morphjet converts on your own computer, so the video never travels over the internet. You can do it with your wifi off.
