About UDim2
A Roblox UDim2 has two axes, each made of a Scale and an Offset: the final pixel size of an axis is scale × parentPixels + offset. Scale stays proportional as the screen resizes; offset is a fixed pixel amount. This tool converts one to the other for a parent size you choose and assembles UDim2.new(xScale, xOffset, yScale, yOffset), plus the UDim2.fromScale and UDim2.fromOffset shorthands. It runs entirely in your browser.
