GD library (GD) is a powerful open-source graphics library that provides extensive image processing and manipulation capabilities. Originally developed in 1999, GD has since become a widely adopted library, particularly for PHP web development, due to its ease of use and versatility.
GD offers a comprehensive range of functions, enabling developers to perform a wide variety of image manipulation tasks, including resizing, cropping, rotating, and applying filters. The library also supports various image formats, including JPEG, PNG, GIF, and WebP, making it a versatile tool for web development and image processing.
