Animated Portable Network Graphics (APNG) is a file format that extends the Portable Network Graphics (PNG) format to support animated images. It is similar to GIF, but offers better support for 24-bit images and 8-bit transparency, which GIF lacks. APNG files contain multiple PNG frames that are displayed sequentially to create an animation. Each frame can have its own delay time, allowing for variable frame rates. APNG is particularly useful for creating simple animations, such as loading indicators, animated icons, and basic looping animations on websites. It is often preferred over GIF due to its superior image quality and transparency capabilities. While GIF is still widely supported, APNG provides a modern alternative for animated images with better visual fidelity. APNG is a widely supported format in modern web browsers, making it a suitable choice for web-based animations. However, older browsers may require extensions or plugins to properly display APNG images. The format is also suitable for use in applications and other software that require animated image support.
