How Adobe Fireworks Hacked PNG to Transform Web Design

In the 1990s-2000s, web designers faced a maddening dual-file workflow: maintaining separate vector source files and raster delivery images. Adobe Fireworks ingeniously exploited PNG's flexible chunk architecture to embed editable vector data within raster pixels, creating files that were simultaneously human-editable and browser-compatible. This technical feat demonstrates how understanding file format specifications can elegantly solve real-world design problems—a principle often overlooked in today's tool ecosystem.
