About 3STF Tools

3STF Tools is a growing collection of 124+ free online tools built for developers, writers, designers, and creators. Existing free utilities run entirely in your browser, do not upload or store your tool inputs, and require no account. Optional accounts provide sync and credit features, while clearly labeled premium AI tools are separate.

Fateh Raiyan Ishmum

Web developer since 2020

Hi, I'm Fateh. I've been building web applications since 2020. I built 3STF Tools because I was tired of ad-covered, tracker-heavy utility sites. My portfolio: fateh.3stf.com.

Our Mission

We believe useful browser tools should respect your privacy and work without a signup wall. Existing free utilities remain free and ad-free. Optional accounts and paid AI features are separate, clearly labeled, and never required to use the free tools.

Privacy First

Free tools labeled as client-side process their inputs locally using JavaScript, so that content never reaches us. If you choose an account, purchase credits, or use a premium AI tool, we process only the information needed to provide and secure that service. We do not use advertising cookies or sell personal information. See our Privacy Policy for the full details.

Built With

  • Next.js & React for the framework
