Why process locally
Many utility websites upload your files to their servers to process them. That means trusting how they store them, how long they keep them and who can access them.
Here each tool is downloaded once into your browser and works with the data on your own computer. You can check it: once the page has loaded, the tools keep working even if you disconnect from the internet.
