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 WebP online free, no account required — WebP is Google's web image format with lossy or lossless compression.

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 WebP
WebP is an image format released by Google in 2010. It supports lossy and lossless compression, transparency and animation.
Websites use it to serve images smaller than the equivalent JPEG or PNG; all current browsers display it.
Some older desktop software and many print services still do not accept WebP files.
Why convert images to WebP? It cuts file sizes by a quarter to a third compared with JPG at the same quality, and every current browser displays it.
