About Cube Diagonal
Most online tools for this task bury what you need behind ads and forms. Cube Diagonal 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. Like everything else in the utility collection, it is free, ad-light, and works on mobile as well as desktop.
