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.
Convert MPEG to MP4 online free, no account required — MP4 is a widely supported video container, usually holding H.264 video and AAC audio.
Change MPEG to MP4 without losing quality — convert MPEG to MP4 free in your browser.
Why does my MPEG video look soft on a modern screen? MPEG-1 and MPEG-2 were designed for VCD and DVD resolution, so upscaling a 576-line picture to 4K shows every limitation of the era.
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.
Why convert video to MP4? Almost every device, browser and platform plays it, so an MP4 almost never needs a second conversion.
What changes when you convert MPEG to MP4
- The MPEG is re-encoded into MP4 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 MPEG to MP4, 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 MP4 file is kept for 2 hours, then deleted.
