What is a .apng file?

APNG (Animated Portable Network Graphics) is a file format that extends the PNG (Portable Network Graphics) specification to allow for animated images. It's essentially an animated version of PNG, offering several advantages over the older GIF format. APNG supports 24-bit color, 8-bit transparency, and better compression, resulting in higher-quality animations with smaller file sizes compared to GIFs. Unlike GIFs, APNG uses true alpha transparency, allowing for smooth and realistic blending of animated elements with the background. This makes it suitable for complex animations with intricate details and subtle visual effects. APNG is commonly used for creating animated stickers, emoticons, loading animations, and other short animated sequences on websites and in applications. While not as universally supported as GIFs, APNG has gained significant traction in recent years, particularly with modern web browsers and image viewers. The format is designed to be backward compatible with standard PNG decoders, meaning that if a program doesn't support APNG, it will simply display the first frame of the animation as a static PNG image. This ensures that APNG images are always viewable, even on older systems.
