About utilstuff.com
A modern, distraction-free digital toolbox designed for developers, creators, and professionals who value speed, privacy, and simplicity.
Why We Built utilstuff.com
Every day, developers and digital creators need quick utility tools: formatting JSON, converting timestamps, decoding Base64, inspecting JWTs, testing Regex, or comparing text diffs. Unfortunately, many online tools are cluttered with popups, require unnecessary signups, or send sensitive code snippets across remote servers.
utilstuff.com was built around a simple principle: the tools should process your input locally, inside your web browser. They rely on the browser’s JavaScript engine and the Web Crypto API, so the data you enter is not uploaded for processing. The website itself still makes ordinary requests to third parties, such as loading web fonts and, where enabled, advertising and consent services; the Privacy Policy explains these. To report a bug, suggest an improvement or ask a privacy question, use the Contact page.
