About ToolNook

Who we are

ToolNook (www.029xazx.com) is a free collection of 100+ browser-based utilities operated by Haoteling, an independent developer. The site launched in September 2026 and covers image processing, PDF operations, text and developer tools, daily-life calculators and casual games.

Our philosophy

Privacy first: tools process your files locally in your browser. Your images, PDFs and text never touch our servers.
Free and unlimited: no sign-up, no usage limits, no paywalls.
Fast and light: static pages that load instantly, with JavaScript loaded only where needed.
Works everywhere: responsive design for phones, tablets and desktops.

How the tools work

Most tools use standard browser technologies (Canvas API, Web Crypto, WebAssembly) to process files directly on your device. Nothing you do in a tool is recorded by us — close the tab and it's gone. The site itself is hosted on Cloudflare's global network.

How we make money

The site is free and supported by unobtrusive display advertising via Google AdSense. See our Privacy Policy for details on cookies and how to opt out of personalized ads.
