Convert PIX to APNG (Animated PNG)

The PIX file extension stands for Alias/Wavefront Run-Length Encoding (RLE) Image Format. Developed by Alias Systems Corporation (later acquired by Autodesk), it was designed for storing bitmap images in PowerAnimator and Alias 3D software. This format was instrumental in creating high-resolution 3D models and animations for movies and video games in the 1990s. The RLE compression minimized file size without compromising image quality, optimizing performance for graphics-heavy tasks. Although its usage has declined in favor of more versatile formats, PIX played a significant role in the evolution of computer graphics technology.

Animated Portable Network Graphics (APNG) is an extension of the Portable Network Graphics (PNG) format designed to support animated images. Introduced in 2004, APNG allows for animated sequences while retaining backward compatibility with non-animated PNG files. This format is utilized for its lossless compression, making it ideal for web graphics where image quality is paramount. APNG files are widely used for animated icons, logos, and other elements that benefit from high-quality animations without the artifacts common in GIF files. Its concise, efficient structure makes it a preferred choice among developers and designers focused on optimizing web performance.
