About APNG files
APNG (Animated Portable Network Graphics) is a bitmap animation format that extends the PNG standard, supporting 24-bit images and 8-bit transparency. Unlike GIF, it offers higher quality with smoother animations and full alpha channel support. While not as widely adopted as WebP, APNG remains useful for complex animations where quality matters. We can convert APNG/PNG to animated WEBP , GIF , AVIF.
