About MPEG to MP4 conversion
MPEG is the older MPEG-1/MPEG-2 video format found on capture cards, older camcorders and archived recordings — most phones, browsers and editors expect MP4 instead. This tool decodes the MPEG video and re-encodes it to a standard H.264 MP4.
Frequently asked questions
Renaming doesn't change the codec inside the file — MPEG-1/MPEG-2 video stays unplayable on devices that only decode H.264. The video needs to be re-encoded, which is exactly what this tool does.
Yes. MP2 or PCM audio commonly found in MPEG files is converted to AAC, matching the re-encoded H.264 video, so the final MP4 plays with sound everywhere.
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.
