A macOS app for creating and breaking down animated PNG files with optimization and compression features.
APNGb is a macOS application that assembles animated PNG (APNG) files from a series of PNG frames and disassembles APNG files back into individual frames. It solves the need for a dedicated, user-friendly tool to create and manipulate APNG animations with optimization features, offering better image quality and smaller file sizes compared to GIFs. The app provides graphical controls for frame delays, playback options, and compression settings.
macOS users, graphic designers, and developers who work with animated images and need to create, optimize, or extract frames from APNG files without using command-line tools.
Developers choose APNGb for its specialized focus on APNG format, built-in optimization techniques to reduce file sizes, and a straightforward macOS interface that simplifies APNG creation and disassembly compared to manual or script-based methods.

Built on Max Stepin's established APNG Assembler and Disassembler executables, ensuring robust performance and compatibility, as credited in the README.
Offers multiple compression methods (zlib, 7zip, Zopfli) and inter-frame optimization techniques to minimize APNG file sizes while maintaining high image quality.
Provides graphical controls for frame delays, playback options, and assembly/disassembly, making APNG manipulation accessible without command-line expertise.
Supports 24-bit color and 8-bit transparency, offering better quality than GIFs, as demonstrated by the README's file size and visual comparison examples.
Only available for macOS 10.11 and above, with no support for Windows, Linux, or web platforms, limiting its user base.
The latest version is 2.0.1 with no mention of recent updates, which may lack modern features, security patches, or compatibility with newer macOS versions.
Relies on third-party executables (APNG Assembler/Disassembler), potentially causing update delays or compatibility issues if those tools are discontinued.
