View APNG Files Online
An .apng file is an animated image saved in the Animated Portable Network Graphic format. APNG files are similar to animated GIF (.gif) files, though not as common. Each APNG file contains a sequence of PNG (.png) frames that comprise the animation.
Many image viewers cannot open APNG files. Therefore, you may want to convert an APNG file to a more common image format, such as GIF, PNG, or JPEG (.jpg), to make it easier to open and share. In some cases, however, conversion software will not preserve an APNG file's animation, even if you convert it to GIF. Instead, the software will save the converted file as a single static image.
NOTE: Many APNG files use the .png extension instead of the .apng extension.
