The reasoning behind the tools: what formats do to pixels, why size matters for sharpness, and how palettes are found.

• 01WebP vs JPEG vs PNG: which format for which imageHow the three main web image formats compress pixels, where each one wins, and a simple decision path for photos, graphics and transparency.
• 02Product photo sizes that look sharpWhy pixel dimensions, zoom, screen density and compression decide how crisp a product photo looks, and how to prepare one master image for every channel.
• 03Building a colour palette from a photoFrom pixels to a usable palette: what extraction algorithms actually do, how to pick roles for each colour, and how to keep text readable.
