Image files are digital files that store visual information, such as photographs or graphics. They come in various formats, including JPEG, PNG, and GIF, each with its own characteristics. For example, JPEG files are commonly used for photographs due to their ability to compress images while maintaining quality, while PNG files support transparency and are often used for web graphics. These files can be viewed on computers, smartphones, and other devices. Image files are essential for sharing visuals online, creating digital art, and enhancing presentations. They can be easily edited using software like Adobe Photoshop or GIMP to adjust colors, add effects, or resize images.
