About Drill Bit

Drill Bit 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. If you find yourself doing this regularly, the rest of the utility suite covers most adjacent tasks with the same approach.
