About Blood Comp
Blood Comp was built for the moment you just need to handle this task and move on — no signup, no upload to a third-party server. 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.
