About Toolden

Free online tools that respect your privacy.

What is Toolden?

Toolden is a collection of free on-device tools for developers, designers, and anyone who works with text, numbers, or data. Format JSON, generate UUIDs, convert colors, count words, and 160 tools — all free, no signup required.

How it works

Every tool runs on your device. Text you paste is processed locally with JavaScript and is never sent to our servers, stored, or logged. Your data stays on your device, always.

Why we built it

Most online tools require signup, upload your data to unknown servers, or bombard you with ads. We wanted something simpler: fast, private tools that just work.

Who we are

Toolden is an independent project built and maintained by a small team. We're developers who got tired of signing up for tools just to format a JSON file.
