About mpgtomp4.com

mpgtomp4.com is a small, focused tool that does one thing: it turns old .mpg video files into .mp4 files that actually play on the devices, browsers, and editors people use today.

Why we built it

Most online video converters work the same way — you upload your file to a server, wait in a queue, and download the result. That model made sense years ago, but modern browsers can now run real video-encoding software directly on your device. We built mpgtomp4.com around that idea: the entire conversion happens locally, in your browser, using a WebAssembly build of FFmpeg. Nothing you convert here is ever sent to us or to any server.

What that means for you

• Your video never leaves your device.
• There's no account, no email, and no sign-up.
• There's no daily limit, credit system, or watermark.
• The tool keeps working even if your internet connection drops, once the page has loaded.

Who this is for

Anyone with an old camcorder archive, a DVD-project export, or a downloaded file that refuses to open in a modern editor or phone. If you just need a working .mp4, this tool is built to get you there quickly and privately.
