About Heritage Sites
When you need this task done in seconds, Heritage Sites delivers a clean, focused interface without the friction of a generic tool. 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.
