képformátum

Képformátum refers to the way digital image data is organized and stored. It defines the file structure, encoding methods, and often the color space and resolution of an image. Different formats are suited for different purposes, balancing factors like file size, image quality, and compatibility.

Common image formats include JPEG (Joint Photographic Experts Group), which is widely used for photographs due to its lossy compression that significantly reduces file size with minimal perceptible quality loss. PNG (Portable Network Graphics) is a lossless format, making it ideal for graphics, logos, and images with sharp lines or transparent backgrounds, as it preserves all original data. GIF (Graphics Interchange Format) is also a lossless format, but it's limited to 256 colors and supports animation, making it popular for simple animations and web graphics.

Other formats include TIFF (Tagged Image File Format), often used in professional photography and printing for its high quality and support for lossless compression. BMP (Bitmap) is a simple, uncompressed format that results in large file sizes but is easy to work with. WebP is a newer format developed by Google that aims to provide superior lossless and lossy compression for web images, often resulting in smaller file sizes than JPEG or PNG at comparable quality. The choice of image format depends on the intended use, whether it's for web display, print, archival, or editing.
