image format

An image format is a way of storing picture data digitally. It determines how the visual information (colors, pixels, details) is organized and compressed for storage and sharing. Different formats, like JPEG, PNG, and GIF, are optimized for specific uses—JPEG for photographs with many colors, PNG for images needing transparency, and GIF for simple animations. Each format balances image quality and file size differently, making some better suited for certain applications. Overall, the format affects how an image looks, how small the file is, and how easily it can be used across devices and software.
