overview

A toolkit that never uploads your files.

AnyTool is a privacy-first toolkit: 1,312 free tools for PDFs, images, video, audio, developers and more.

Every tool runs on your own device, so files never leave the browser. No sign-up and no limits, and once loaded, most tools keep working with Wi-Fi off.

  1. Architected a 100% client-side Next.js platform with 1,462 static routes. Processing and AI run on the device (WebAssembly, Web Workers, Transformers.js, MediaPipe), so files never leave the browser.
  2. Built offline mode with a service worker: once loaded, most tools reopen and work with Wi-Fi off, even after a browser restart (10 of 10 passed in production tests).
  3. Led a security audit of the 37 security tools: 102 findings, all 15 high-severity issues fixed and 60 fixes in total, each proven by automated old-versus-new browser checks.
  4. Grew discovery with technical SEO and AI-answer optimisation (structured data, IndexNow): AnyTool pages were cited 23,000+ times in AI answers from Microsoft Copilot and partners in 3 months.
  5. Protected the code without tracking users: a proprietary licence, build-time provenance markers, a domain lock and blockchain-timestamped evidence.

Heavy work, done in the tab.
