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 the best tools are the ones that respect your privacy and just work. No popups asking you to sign up, no ads cluttering the interface, no "premium" tiers locking features behind paywalls. Just fast, useful tools that get out of your way.

Privacy First

Every tool on 3STF Tools processes data locally in your browser using JavaScript. Your text, images, passwords, and files never leave your device. We don't use cookies for tracking, we don't collect personal data, and we don't sell anything. What you do with our tools is your business alone.

Built With

  • Next.js & React for the framework
  • Tailwind CSS for styling
  • TypeScript for type safety
  • Vercel for hosting
  • Web APIs (Canvas, Crypto, Speech, and more)
