one image, every platform. got tired of resizing the same image into twelve aspect ratios, so i built a tool that does it automatically.
react, node.js, stability ai, canvas api.
the problem
instagram wants 1:1, twitter needs 16:9, linkedin prefers 1.91:1. each platform crops differently, and manually adjusting the same image takes hours.
auto resize
upload one image, get all the sizes you need.
corner correction
automatic cropping cuts off important stuff, so stability ai fills in the edges intelligently and keeps the composition intact.
