Why Animated PNGs? — Animated PNGs are the best solution at this time to get better GIF-esque animation to the web & beyond.

I am using Animated PNGs actively and live-in-production in my various projects right now(Here and Here). Animated PNG gives users an option to save their animation in a portable format without losing so much quality as they would with Animated GIF(Which is limited to 10 frames per second, 256 colors, and only simple transparency).
Animated PNGs work very well with these apps and would work well with countless others for a few main reasons:

They can be used now. The Animated PNGs generated from my apps get more lively and more interesting with the animations running, but they still work as a non-moving image. For users viewing them on a browser that does not support Animated PNG, they still get the job done with a single-frame image being shown. They just don't have that extra goodness added by animation.

Low complexity. Given the simplicity of the format and that it mostly leverages the existing PNG technologies, AnimatedPNG is easy for developers to implement in their projects and software.
There are many resources and sources of information out there that developers can use to figure out and work with Animated PNGs. I have tried to work with other similar formats, but have not had such an easy time getting my hands on the needed information to encode such formats.
If a format is too complex and the needed technical information about it is hard to come by, the barrier for developers to embrace it may be too high, even if they want to.
There are many tools, plugins, and software for working with Animated PNGs out there already.

PNGs, Everywhere! Regular PNG is here to stay for the foreseeable future and as long as they are around, which might be forever, we may as well have animations supported on them when it takes such little resources to support that. Even if a more advanced solution for this type of animation becomes viable, we won't be dropping PNG any time soon and it doesn't hurt to have them animate.

About APNGs

Welcome to, the go-to portal for APNGs(Animated PNGs).
APNGs are animated images, similar to Animated GIFs. Unlike GIFs, however, APNGs support a full spectrum of 16 million colors and unlimited framerate. GIFs are limited to 256 colors and 10 frames per second. After a long journey of ups and downs, APNGs are gaining momentum and interest and could be poised to be the successor to GIFs.

Let us welcome the latest browser/rendering engine to support APNGs!
Good to have you with use Apple Safari/WebKit!
Gaining Safari is a big development for APNGs.
Apple users have a tendency to be in tight-knit groups and use Apple-everything without caring what other systems are doing. Having access to this type of community is good for the format because they may be inclined to simply use APNGs, have them work on their Mac, iPhone, and iPad, and not care if some other browser out there doesn't support it. Most of their friends probably use all Apple stuff too, so they may not be bothered by the non-support of other technologies. Apple is also a very influential company, obviously and having support on their devices can boost morale and perception of the format.

Browser Support

FirefoxHas the longest history of supporting APNGs. In fact, this animated extension of PNG was designed by Mozilla folks.
SafariSafari is the default browser for Macs. WebKit, Safari's rendering engine, powers all browsers on iOS, meaning iPhones, iPads, and iPods with iOS 8+ now support APNGs.
