About QuickToolsBox

Built by an Independent Developer
QuickToolsBox is a solo project — designed, built, and maintained by a single independent developer. It started as a personal need for a clean, distraction-free place to run common web tasks without pasting sensitive data into random websites. If you find it useful, that's the whole point.
New tools are added regularly. If you have a suggestion or run into a bug, feel free to get in touch.
