JPG Joint Photographic Experts Group
JPG (JPEG) is the most widely used image format, established by the Joint Photographic Experts Group in 1992. It employs lossy compression, achieving significant file size reduction (90-95%) while maintaining acceptable visual quality. This makes it particularly suitable for photographs and images where file size is a priority.
The format supports 24-bit color depth, resulting in a palette of over 16 million colors. Quality can be adjusted on a scale from 1 to 100, but repeated saving can lead to generation loss, where quality degrades with each compression cycle. JPG is ubiquitous across digital cameras and online platforms, making it the go-to format for sharing images.
While JPG excels at compressing photographic images, it lacks support for transparency and is not ideal for images that require extensive editing or layering. It is best suited for web images, social media, and any scenario where small file size is more critical than maintaining the highest quality.[1][2]
