Project: What's In A GIF - GIF Explorer

This page will allow you to explore the different parts of an existing GIF file. You will be able to explore the different blocks and can view both the decoded content as well as the raw bytes for each section.

This particular decoder was written in pure, vanilla javascript. All decoding happens locally within your browser. This means you will need a relatively modern browser to run this code.
