What is an JPG file?
A JPG file, also known as a JPEG (Joint Photographic Experts Group), is a commonly used image file format. It is a lossy compression technique that significantly reduces the file size of images while maintaining a reasonably high image quality.
JPG files are widely utilized for storing and sharing digital images, photographs, and graphics on various digital platforms.
More Information.
The JPG file format was developed to streamline the sharing of photographic images and graphics over the Internet.
Its creation marked a significant advancement in digital imaging technology, allowing users to store and transmit images without significantly compromising their quality.
Its widespread adoption was largely due to its ability to strike a balance between image quality and file size.
Origin Of This File.
The JPG file format was created by the Joint Photographic Experts Group in 1992. The group aimed to develop a standard for image compression, enabling efficient storage and transmission of digital images.
Over the years, it has become one of the most popular and widely supported image formats across different operating systems and software applications.
File Structure Technical Specification.
A JPG file consists of compressed image data that can be decompressed and rendered by various image-viewing software.
It utilizes a lossy compression algorithm that discards some of the image data to reduce the file size. JPG files support 24-bit color, making them suitable for displaying high-quality images.
The file structure consists of various segments, including the image metadata, image data, and quantization tables that govern the compression process.
