The Animated Portable Network Graphics (APNG) is an unofficial extension of the Portable Network Graphics (PNG) format. APNG patch provides APNG support to libpng. APNG support was merged! https://github.com/pnggroup/libpng/pull/706

The APNGKit project is a high-performance framework for loading, displaying, and animating images in the UIKit / AppKit ecosystem (iOS, macOS, tvOS), specifically targeting the APNG (Animated PNG) image format. Unlike traditional static PNG images, APNG supports frame-by-frame animation with full-color images and transparency — yielding better visual fidelity than GIFs while remaining efficient. APNGKit offers a friendly API (e.g. APNGImage, APNGImageView) that behaves similarly to the standard image/image-view pattern, making it easy for iOS/macOS developers to adopt without learning complex new APIs. ...

Pencil2D is an animation/drawing application for OSX, Windows and Linux. It lets you create traditional hand-drawn animations (cartoons) using both bitmap and vector graphics.

Creates highly optimized Animated PNG files from PNG/TGA image sequences. CLI versions available for all major OSes. GUI versions for Windows and macOS. Also, APNG Disassembler can be found at http://sourceforge.net/projects/apngdis

This program converts APNG animations into animated GIF format. Wu64 quantization is used for true-color files. Transparency is handled either using a threshold, or composed over chosen background color. CLI version is OS-independent, GUI version is available for Windows. Another converter: http://sourceforge.net/projects/gif2apng

This program converts APNG file into a sequence of individual PNG frames. Command-line interface and GUI viersions. Also, APNG Assembler can be found at http://sourceforge.net/projects/apngasm

This program converts GIF animations into animated PNG format. Usually it makes the files smaller. CLI version is OS-independent, GUI version is available for Windows. Another converter: http://sourceforge.net/projects/apng2gif

...The repository splits out independent submodules such as YYModel (a high-performance JSON ↔ model mapping layer), YYCache (a fast caching system), YYImage (image handling, including support for formats like WebP, APNG, GIF), YYWebImage (asynchronous image loading and caching), YYText (a rich text display and editing component), YYKeyboardManager (keyboard/input management), YYAsyncLayer, YYDispatchQueuePool, and various handy Categories that extend Foundation/UIKit with utility methods. YYKit is intended to be modular, though historically some interdependencies exist, which is why the author suggests using the individual components where possible instead of the entire monolithic library.

...It integrates tightly with the rest of the YYKit ecosystem and uses YYCache for memory and disk caching and YYImage for animated image support, which means it can handle formats such as WebP, APNG, and GIF smoothly in your UI components. The framework provides easy-to-use category extensions for UIImageView, UIButton, CALayer, and other UI elements so developers can assign a URL and let the library handle the download, decode, and display process asynchronously without blocking the main thread. It supports progressive and interlaced image decoding, which improves perceived loading performance by showing partial images earlier.

The goal of this project is to create an application which can convert animated gif files into animated apng files.
