About MP4
MP4 (MPEG-4 Part 14) is a container format standardised by ISO. It usually holds H.264 or H.265 video with AAC audio, and it can also carry subtitles and chapter markers.
It is the most widely supported video format: phones, browsers, smart TVs and video sites all play it.
The video inside an MP4 is almost always compressed with a lossy codec, so every re-encode loses a little quality.
Convert MP4 to MPEG online free, no account required — MPEG is the MPEG-1 and MPEG-2 video format behind Video CD and DVD.
Change MP4 to MPEG without losing quality — convert MP4 to MPEG free in your browser.
Why is my MP4 file so large? MP4 video is already compressed with H.264 or H.265, so a lower bitrate or resolution shrinks the file at the cost of some quality.
About MPEG
MPEG files (.mpg, .mpeg) are MPEG-1 or MPEG-2 program streams, the standards behind Video CD and DVD video.
Older camcorders, DVD-era video files and broadcast archives.
MPEG-1 and MPEG-2 compress far less efficiently than H.264, so the files are large for their quality.
Why convert video to MPEG-2? DVDs and some broadcast hardware only accept it, so disc authoring still requires it.
What changes when you convert MP4 to MPEG
- The MP4 is re-encoded into MPEG at the default quality settings, so the result looks close to the original but is not bit-identical.
Settings you can change
Before you convert MP4 to MPEG, you can adjust: Video codec, Rate control, Quality (CRF), Video bitrate, Resolution, Width, Height, Scale fit, Frame rate, Encoder preset, Audio codec, Audio bitrate, Trim start, Trim duration, and Remove metadata.
Limits
Each plan sets a maximum file size and a number of conversions per day, and video and audio files also have a maximum length. Guests can convert files up to 100 megabytes and 5 per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your converted MPEG file is kept for 2 hours, then deleted.

Do I need an account to convert MP4 to MPEG?
No. You can convert MP4 to MPEG without an account; signing in raises the file-size and daily limits.
How long is my converted MPEG file kept?
The MPEG file you convert from MP4 is kept for 2 hours, then deleted automatically.
When I convert MP4 to MPEG, is the video re-encoded?
The MP4 is re-encoded into MPEG at the default quality settings, so the result looks close to the original but is not bit-identical.
Will converting MP4 to MPEG change my original file?
No. The conversion reads your MP4 and writes a new MPEG file, leaving your original MP4 file untouched.
