About DPI Checker
Most online tools for developer and design work bury what you need behind ads and forms. DPI Checker takes the opposite approach: load the page, do the job, leave. 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 pairs naturally with the other developer utilities here when you need to chain a quick workflow.
