Image file formats define how digital pictures are encoded and stored as grids of colored pixels. They range from uncompressed formats preserving every detail for professional editing to compressed formats reducing file size for web and sharing. Common uses include photography, graphic design, medical imaging, and social media. Each format balances quality, file size, and features like transparency or animation, making image selection crucial for performance and visual fidelity across applications.
Portable Network Graphics (PNG) stores raster images with lossless compression, preserving every pixel detail exactly. Unlike its predecessor GIF, PNG supports full alpha transparency and millions of colors, making it ideal for web graphics, logos, screenshots, and images requiring text overlays. Its patent-free design ensures broad compatibility across browsers and image editors.
