ToolBox.io is a collection of free, browser-based tools designed for developers, designers, content creators, students, and anyone who needs quick online utilities.
Every tool runs 100% in your browser — your data never leaves your device. No accounts, no sign-ups, no fees. Just open a tool and start using it instantly.
We believe essential developer and productivity tools should be free, fast, and private. Instead of downloading apps or signing up for services, you should be able to generate a QR code, format JSON, or create a strong password in seconds.
