Convert PCT to APNG (Animated PNG)

The PCT (Personalized Image Capture Technology) file extension, developed by Apple in 1984, is a graphics file format used primarily for exchanging images between Macintosh applications. It supports both vector and bitmap graphics and was the native format for the QuickDraw graphics library. Over time, PCT has been largely replaced by PDF, but it remains supported by some applications for legacy purposes.

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.
