What is JPG?
JPG, short for Joint Photographic Experts Group, is a widely used image file format that employs lossy compression to reduce file size while maintaining acceptable visual quality. Developed by the Joint Photographic Experts Group committee in 1992, it became an international standard (ISO/IEC 10918-1) and is now ubiquitous in digital photography, web publishing, and social media. In India, JPG is the default format for smartphone cameras, online portals (e.g., government documentation uploads, e-commerce product images), and printing services. Its balance between quality and size makes it ideal for storing large photo libraries and sharing images on bandwidth-limited networks. The format is commonly encountered in competitive exams like NTA UGC NET (Paper I: ICT) and SSC CHSL when discussing file types or digital media basics. Despite its popularity, JPG faces competition from newer formats like WebP and HEIF for web optimization. Understanding JPG is essential for anyone working with digital images, from graphic designers to common users uploading Aadhaar photos or passport-size pictures online.

JPG — frequently asked questions
What is the full form of JPG?
JPG stands for Joint Photographic Experts Group, the committee that created the JPEG image compression standard.
Are JPG and JPEG the same thing?
Yes, JPG and JPEG are essentially the same format. JPG was introduced when some older systems required a three-letter file extension, while JPEG uses the full four letters.
How does JPG compression work and does it affect image quality?
JPG uses lossy compression that discards some image data to reduce file size. Higher compression leads to smaller files but can cause visible artifacts, especially in areas with sharp edges or uniform color.
