Any secure RAR to ZIP converter that works offline?

I had the exact same concern because I work with confidential data every day. Uploading archives to random online sites always felt risky. That’s when I discovered** Softaken Archive Converter**, an offline solution that installs directly on Windows. It doesn’t need internet at all, so all your files stay secure on your own computer. The software converts RAR files to ZIP in just a few clicks, and it even supports batch conversion if you need to process multiple files. I’ve used it with client projects and never faced corruption or data loss. It’s paid, but for sensitive files, totally worth it.
