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 file size while maintaining quality, while PNG files support transparency and are often used for web graphics. These files can be created using cameras, smartphones, or graphic design software. Image files are essential for digital communication, allowing users to share visuals easily across platforms like social media, websites, and emails. They can also be edited using software like Adobe Photoshop or GIMP.
