Regressive JPEGs is an experimental web tool that visualizes the progressive decoding stages of JPEG images. It allows users to upload a JPEG file and see how the image is reconstructed block by block as the data is read, mimicking how older modems or slow connections might have displayed images. This provides a fascinating, albeit abstract, look into image compression and transmission processes.
