About the MP4 format
MP4 — MPEG-4 Part 14
MP4 is the world's most widely used video format, adopted universally across devices, streaming platforms, and video editing software. Based on the MPEG-4 standard, it delivers excellent video quality at relatively small file sizes.
Common uses
- Online video streaming (YouTube, Netflix)
- Social media videos
- Smartphone video recording
- Digital downloads and purchases
About the JAR format
JAR — Java Archive
A JAR file is a ZIP archive that packages compiled Java classes, resources and a manifest into one distributable file. Because the container is plain ZIP, a JAR can be opened, repacked or converted with any archive tool — the only thing that makes it a JAR is the META-INF/MANIFEST.MF entry.
Common uses
- Packaging a Java library or application for distribution
- Inspecting or extracting the contents of a compiled Java program
- Converting a ZIP of class files into a loadable JAR
- Repacking a Minecraft mod or plugin archive
