About toolsy.one

toolsy.one is a growing collection of small, fast web tools — for developers, writers, students and anyone who just needs to get something done. The idea is simple: everyday utilities should be quick to load, pleasant to use, and completely private.

Our principles

• Privacy by design. Almost every tool runs entirely in your browser. The text you paste, the numbers you enter and the passwords you generate are processed on your device and are never uploaded to a server.
• Free and open to all. The tools are free to use. The site is supported by advertising so we can keep them that way.
• Genuinely useful. Each tool comes with a clear explanation of how it works and how to get the most out of it — not just a button.

Who maintains it

toolsy.one is built and maintained by the toolsy.one team — a small, independent group that designs, builds and tests each tool and writes the accompanying guides. We keep the tools accurate and up to date; if you spot something wrong, please let us know.

How it’s built

The site is a fast static site with no tracking of the content you process. Where a tool needs to do real cryptographic work — like generating passwords or hashes — it uses the browser’s built-in Web Cryptography API rather than sending anything across the network.
