About MPG to MP4 conversion
MPG is the classic MPEG-1/MPEG-2 container used by old camcorders, capture cards and DVD-era software — it plays poorly, if at all, on modern phones and browsers. This tool decodes the MPEG-1/2 video and re-encodes it to a standard H.264 MP4.
Frequently asked questions
Camcorder recordings, TV capture-card exports and other MPEG-1/MPEG-2 video, with MP2 or MP3 audio — the video is re-encoded to H.264 and the audio to AAC so the result plays on any device.
They're the same underlying format — .mpg and .mpeg are just different file-extension conventions for MPEG-1/MPEG-2 video. Both convert to MP4 the same way.
No. The conversion runs entirely in your browser using WebAssembly (FFmpeg). Your file never leaves your device — that is also why there is no upload wait, no queue and no file-size pricing.
Up to 8GB on desktop browsers and 2GB on mobile. There is no limit on the number of files you convert, and no signup or watermark.
Yes — completely free and unlimited, with no watermark, no signup and no daily quota. Because the conversion runs on your own device instead of our servers, there are no processing costs to charge for.
If the source already contains H.264 video, the file is rewrapped without re-encoding and finishes in seconds, even for gigabyte files. Other codecs are re-encoded in parallel WebAssembly workers, which runs at roughly real-time speed on a modern computer.
Yes. It runs in any modern browser — Chrome, Safari, Edge or Firefox — on Windows, macOS, ChromeOS, Linux, iOS and Android. There is nothing to install.
AAC and MP3 audio is copied over unchanged. Other audio codecs (PCM from cameras, Vorbis, Opus…) are converted to AAC so the resulting MP4 plays everywhere.
