About DPI Calc
DPI Calc was built for the moment you just need to handle developer and design work and move on — no signup, no upload to a third-party server. Everything happens client-side, which means your files and data never leave your machine. The interface is intentionally minimal so you can focus on the task instead of learning the tool. It is one of about a hundred developer tools that share the same philosophy: do one thing, do it well, get out of your way.
