About Mag Flux
Working with this task no longer requires installing heavy desktop software — Mag Flux runs entirely in your browser, instantly. 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 utility tools that share the same philosophy: do one thing, do it well, get out of your way.
