MPEG to MP4 Converter

None. Both extensions mark the same kind of MPEG video file. The shorter .mpg dates from the days when Windows file names allowed only three letters after the dot. This converter accepts either one.

An .mpeg file holds MPEG-1 or MPEG-2 video, codecs from the 1990s. An MP4 normally holds H.264, which delivers the same picture in a fraction of the space and plays on every current phone, browser and TV.

VLC plays MPEG-1 and MPEG-2 on Windows, Mac and Linux. iPhones and Chrome do not play these files, and many upload forms reject them. That is where converting to MP4 helps: the result opens in the default player of any device.

Yes. Open this page in Safari, tap “Upload a file”, choose the .mpg or .mpeg in the Files app and download the MP4. The iPhone plays it straight from Files, or after you save it to Photos.

A little, because the video is re-encoded from MPEG-2 or MPEG-1 to H.264. The resolution and frame rate stay the same, but the MP4 cannot add detail that the original recording never had.

No. You upload the file in the browser, and the conversion runs on our server. There is nothing to install and no trial version to remove later. The page works the same on a Windows PC, a Mac, a Chromebook or a phone.

Yes, 1 GB per file. At typical DVD bitrates, an hour of MPEG-2 takes two gigabytes or more, so a long TV recording has to be split before you upload it.

Uploads travel over HTTPS. The source file and the finished MP4 are both deleted from our servers within minutes of the conversion, and neither is shared with anyone.
