About Vol Fraction
Most online tools for this task bury what you need behind ads and forms. Vol Fraction 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 utility utilities here when you need to chain a quick workflow.
