MD2 to JFIF Converter

MD2 is Quake II's model format: one mesh whose frames are baked vertex-by-vertex into the file — the original "vertex animation" that predates skeletal rigging. Every enemy, weapon and pickup in Quake II (1997) is an MD2, and the format became the de-facto standard for early modding.

three.js parses MD2 including its frame data, so a converted glTF carries the animation frames as morph targets — the retro look arrives intact in modern engines.

JPG (short for JPEG, the Joint Photographic Experts Group committee that standardized it in 1992) has been the default photo format for over three decades. It compresses photographs using the discrete cosine transform: the image is split into 8×8 blocks, and details the human eye is bad at noticing are discarded. The result is files many times smaller than uncompressed data, at a quality level you control when saving.

In practice JPG is unbeatable for photographs and smooth gradients — camera memory cards, messaging apps and the web all assume it. It is a poor fit for screenshots, logos or anything with sharp edges and flat color, where compression leaves visible ringing around text. There is no transparency support, color depth is capped at 8 bits per channel, and every re-save with compression compounds tiny generational losses.
