Image formats fall into three main categories: uncompressed, compressed, and vector. Uncompressed formats like BMP were popular in the early days, offering high-quality images but at the expense of larger file sizes. However, as the Internet emerged and the need for faster file transfers intensified, compressed formats like JPG gained traction. These offer reduced file sizes but at the cost of some image quality. In recent times, modern technology has introduced advanced compressed formats like WebP, which strike a balance between image quality and file size. Vector formats like EPS and SVG ensure quality at any scale by storing geometric data. However, compatibility issues are common as not all applications and browsers support every image format, making image conversion tools essential for easily changing formats.
