About
Built for people who just need the tool.
No accounts. No subscriptions. No file uploads to servers. Just open the tool and use it.
What is boxtool.io?
boxtool.io is a growing collection of free, browser-based micro-tools for developers, designers, and creators. Everything runs locally in your browser — no files are ever uploaded, stored, or shared with any server.
Why we built it
We got tired of searching for a simple tool — a JSON formatter, a QR code generator, a color picker — and landing on bloated sites full of ads, paywalls, and sign-up prompts just to do one thing. boxtool.io is the answer to that frustration: a clean, fast, no-nonsense toolbox that respects your time and your privacy.
Privacy first
We do not collect, store, or transmit your files or personal data. All processing happens entirely in your browser using client-side JavaScript. You can read our full Privacy Policy for details.
Who maintains it
boxtool.io is an independent project maintained by a small team passionate about useful software and clean design. We ship new tools regularly based on what people actually need.
Support the project
boxtool.io is free and will stay free. If it saves you time, consider supporting us via Buy Me a Coffee. Every contribution helps keep the lights on and new tools coming.
