Convert MPEG to WebM
Updated Jul 2026
MPEG is the older format used by DVDs and broadcast video, while WebM is the compact format browsers use for streaming. To convert MPEG to WebM, open the file in a converter and export it in WebM. Doing this on your own computer means the footage never has to travel to someone else's server first.

How to convert MPEG to WebM
- Open Morphjet and drag in the MPEG file, or a whole folder of them, to convert several at once.
- Choose WebM as the output format.
- Convert. The WebM file is written right next to the original, and nothing is uploaded anywhere.
MPEG vs WebM: what actually changes
| MPEG | WebM | |
|---|---|---|
| File size | Larger, older compression | Smaller, modern compression for the same quality |
| Quality | Good, but less efficient per megabyte | Good, with a small one-time loss on export |
| Plays in web browsers | Inconsistent, often needs a plugin or extra software | Yes, built for the web |
| Plays on DVD players and older TVs | Yes, this is what it was built for | No |
| Common source | DVDs, broadcast recordings, older camcorders | Websites, video calls, screen recordings |
| Editing software support | Wide, especially older tools | Growing, but less universal than MPEG |
When to convert, and when not to
Convert MPEG to WebM when you want to put old footage, like a DVD rip or a broadcast recording, on a website or app where it needs to stream cleanly at a smaller file size.
Keep the MPEG original if you're archiving the footage or plan to play it on a DVD player or older TV, since WebM won't work there and every conversion re-compresses the video a little.
Why not just use an online converter?
MPEG files are often old home videos, family recordings, or personal footage pulled off a DVD, not the kind of thing you want sitting on an unfamiliar server just to change formats. An online converter has to upload the whole video before it can hand back a WebM copy. Converting on your own computer keeps that footage exactly where it started, on your machine.
Questions
Does converting MPEG to WebM lose quality?
There's a small, one-time quality loss because WebM re-compresses the video on export. At a reasonable quality setting it's hard to notice, especially for footage that's going on the web anyway.
Will a WebM file play on a DVD player or an older TV?
No. WebM is a web format, and DVD players and most older TVs don't recognize it. If you need to play the video on that kind of hardware, keep the MPEG version around too.
Why convert old MPEG video to WebM at all?
MPEG files are usually large and don't play smoothly in a browser without extra software. WebM is smaller for the same quality and is built to stream directly on websites and in web apps.
Can I convert MPEG to WebM without uploading the video anywhere?
Yes. A desktop app like Morphjet converts the file locally on your own computer, so the footage never has to leave your machine or pass through anyone else's server.
Can I convert a whole folder of old MPEG recordings at once?
Yes. You can drag an entire folder into Morphjet and it converts every file to WebM in one pass, which is useful if you're digitizing a batch of old DVDs or recordings.
Morphjet converts MPEG, WebM, and 1,800+ other formats, all on your machine. Launching this July.
