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 JPEG online free, no account required — JPEG is the universal lossy photo format.

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 JPEG
JPEG is the standard lossy image format, named after the Joint Photographic Experts Group that published it in 1992. It shrinks photos to a fraction of their raw size by discarding fine detail.
Photos from cameras and phones, images on the web and email attachments; every device and app opens it.
JPEG has no transparency, stores 8 bits per colour channel, and loses a little more quality every time it is saved again.
Why convert photos to JPG? It is the one image format every website, app and photo service accepts, and at high quality settings the loss is invisible.
