About go-supertools

go-supertools is a growing collection of free online tools — converters, formatters, generators, calculators, image and video utilities, and website, DNS and security checkers. There are 288 tools today.

What we care about

• Private by default. Most tools run entirely in your browser, so your files and text never leave your device. Each tool page says clearly whether it runs locally or looks up live data on our server.
• No signup, no limits. Open a tool and use it.
• Fast and plain. Small pages, no popups, no gating of results.
• Honest. Where a result is only indicative (for example the malware check), the page says so. Tools that don't work yet are hidden rather than shown broken.

How it's run and funded

The site is built and maintained by a small independent team and runs on Cloudflare's network. It is free to use. To cover running costs we may introduce unobtrusive advertising in the future; if we do, it will only load after you give consent, and it will never sit in the way of a tool's result.
