A macOS app for assembling and disassembling animated PNG (APNG) files with optimization and compression.
APNGb is a macOS application that assembles animated PNG (APNG) files from a series of PNG frames and disassembles APNGs back into individual frames. It solves the need for creating high-quality, optimized animations with better color and transparency support than GIFs, offering features like frame delay adjustment and compression options. The app is built on top of proven executables by Max Stepin, ensuring reliability and efficiency in APNG handling.
macOS users, such as graphic designers, web developers, and content creators, who need to create or edit animated PNG files for web projects, presentations, or digital media with enhanced visual quality.
Developers choose APNGb for its dedicated focus on APNG manipulation, providing a native macOS interface with advanced optimization tools that reduce file sizes while maintaining 24-bit color and 8-bit transparency. It offers a free, open-source alternative to proprietary animation software, leveraging well-established underlying technologies for robust performance.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Uses inter-frame optimization, alpha-blend, and compression options like zlib and Zopfli to minimize APNG file sizes while maintaining quality, as detailed in the assembling feature.
Supports 24-bit color and 8-bit transparency, offering superior image quality compared to GIFs, with examples showing smaller file sizes for the same content.
Provides a native macOS GUI for easy APNG assembly and disassembly, including frame delay control and playback options, as shown in the app screenshots.
Built on proven executables by Max Stepin (APNG Assembler and Disassembler), ensuring robustness and backward compatibility with non-animated PNG viewers.
Only available for macOS 10.11 and above, excluding users on Windows, Linux, or other operating systems without workarounds.
Lacks a command-line interface or scripting support, making it unsuitable for automated or batch processing tasks in development pipelines.
Last stable release was version 2.0.1 in 2019, which may lead to compatibility issues with newer macOS versions or lack of modern features.
