Pendulum

About Pendulum

Pendulum is a free, browser-based utility designed to make this task as quick and frictionless as possible. 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.
