## Description

Gifski is a high-quality GIF encoding engine designed to convert video files and PNG sequences into high-fidelity animations. It focuses on maintaining visual quality through the use of advanced color palettes and dithering.

The engine employs cross-frame palette quantization to ensure visual consistency across animations and uses temporal dithering to simulate higher color depth. It also incorporates lossy compression to manage the resulting file size.

The project is available as a C API library for embedding into native software applications and provides a WebAssembly compilation target for integration into web browsers.
