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 WebM online free, no account required — WebM is an open, royalty-free web video format with VP8, VP9 or AV1 video and Opus or Vorbis audio.
Change MPEG to WebM without losing quality — convert MPEG to WebM 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 WebM
WebM is an open, royalty-free video format developed by Google and based on the Matroska container. It holds VP8, VP9 or AV1 video with Vorbis or Opus audio.
It is made for the web: all major browsers play it in the HTML video element, and it is common for screen recordings and short clips.
WebM allows only its own small set of codecs, so H.264 video or AAC audio has to be re-encoded to fit.
Why convert video to WebM for a website? Browsers play it without plugins, and VP9 or AV1 compresses smaller than H.264 at the same quality, so pages load faster.
What changes when you convert MPEG to WebM
