Images are the backbone of digital content, and choosing the right format is crucial for website performance, design, and SEO. Among the most widely used image formats is JPG (or JPEG). In this guide, we’ll explain everything about JPG format—its advantages, disadvantages, real-life use cases, and when to use it.

What is JPG Format?

JPG stands for Joint Photographic Experts Group, the organization that created this format. It is a lossy image format, meaning it compresses images by reducing some data to make the file smaller.

JPG is known for its high compression capability while maintaining reasonable image quality, which makes it the most popular choice for digital photographs, websites, and social media.

In simple terms, JPG is a versatile image format designed to balance file size and image quality, making it ideal for web and multimedia use.
