Convert MP4 to MPEG
Updated Jul 2026
MP4 is the video format almost everything plays today, from phones to browsers to streaming apps. MPEG is the older standard that DVD authoring tools and some broadcast systems still expect. To convert MP4 to MPEG, open the file in a converter and export it as MPEG, without uploading anything, since it can all happen on your own computer.

How to convert MP4 to MPEG
- Open Morphjet and drag in the MP4 file you want to convert. Add one file or a whole folder at once.
- Choose MPEG as the output format.
- Convert. The MPEG file is written next to your original, and nothing leaves your machine.
MP4 vs MPEG: what actually changes
| MP4 | MPEG | |
|---|---|---|
| Plays on modern devices | Yes, universal support on phones, browsers, and streaming apps | Limited, mostly older or specialized hardware |
| File size | Smaller, modern compression | Larger for the same quality, older compression |
| Quality | Good, efficient lossy compression | Lower, and re-encoding from MP4 adds a second round of loss |
| DVD and broadcast authoring | Not directly supported | Yes, the format these systems expect |
| Web and streaming use | Yes, the standard for web video | Rare, not built for streaming |
When to convert, and when not to
Convert MP4 to MPEG when you need the video for DVD authoring software, a broadcast system, or older professional equipment that only reads the MPEG standard.
Keep the MP4 if the video is headed anywhere modern, like the web, a phone, or a streaming service, since MP4 already does that job with better compression and no extra quality loss.
Why not just use an online converter?
A video file, especially a personal one, isn't something you want sitting on a stranger's server just so it can change format. An online converter uploads your MP4, processes it somewhere else, and sends back an MPEG, which means a copy of your video existed on another machine, even briefly. Converting on your own computer keeps the video, and whatever it shows, on your machine the whole time.
Questions
Does converting MP4 to MPEG lose quality?
A little. MPEG uses an older, less efficient compression than MP4, so re-encoding adds a second round of lossy compression on top of whatever the MP4 already had. For DVD or broadcast use it's usually fine, but it isn't a lossless conversion.
Why would I need MPEG instead of MP4?
MPEG is still the format DVD authoring software and some broadcast or professional video systems expect, since it predates MP4. If you're not working with that kind of hardware or software, MP4 is the better choice to keep.
Will the audio stay in sync after converting?
Yes. The conversion re-encodes the video and audio together, so timing is preserved. What changes is the compression method, not the sync between picture and sound.
Can I convert MP4 to MPEG without uploading the file?
Yes. A desktop app like Morphjet converts the file on your own computer, so the video never travels over the internet. You can do it with your wifi off.
