About Internet Tool Box
Internet Tool Box (internettoolbox.it) is a free collection of small, focused web utilities — the kind of tools you reach for once a month and never want to sign up for.
What we build
We publish a growing library of everyday utilities: password generators, JSON formatters, unit and duration converters, QR code generators, image compressors, regex testers, date calculators, cron builders, and more. Each tool does one thing and tries to do it well, with a clean interface that works on both desktop and mobile.
Every tool is self-contained. No tool depends on another tool, so the page loads fast and stays responsive, even on low-end phones or slow networks.
How it works (and why it's different)
Every tool on this site runs entirely in your browser. Nothing you type, paste, generate, or upload ever leaves your device. There is no server that receives your data, because there is no server-side processing at all — the whole application is a static, client-only progressive web app.
Concretely, that means:
- No accounts. You don't register, you don't log in, and we don't know who you are.
- No uploads. When a tool accepts a file (audio, image, SVG), the file is processed locally via the File API and Web Workers. It never travels over the network.
- No analytics of your content. We don't see the passwords you generate, the JSON you format, or the text you paste. We couldn't, even if we wanted to.
- Works offline. The first time you visit, the service worker caches the app shell. After that, most tools work without a network connection.
Our principles
- Privacy by construction. Because there is no backend, there is nothing to leak, nothing to subpoena, and nothing to store.
- Speed matters. Tools are lazy-loaded, so you only download the code for what you're using. Bundle sizes are intentionally kept small.
- Accessibility is default. Every tool uses semantic HTML, keyboard-friendly controls, labeled inputs, and sensible color contrast. Dark and light themes are both first-class.
- No dark patterns. No "free trial that bills you later", no email walls, no fake urgency. Use the tool, close the tab.
How we fund the site
Internet Tool Box is funded by a small number of display ads shown on tool pages. Ads are served by Google AdSense and only appear when a tool has actual content on screen — never on loading states, 404 pages, or legal pages. If you'd rather not see them, an ad blocker is totally fine with us; the tools will work identically.
Who runs it
Internet Tool Box is an independent project. We are a small team that likes building useful things in the open, without forms or paywalls in the way. If you've found a bug, want to suggest a new tool, or just want to say hello, the contact page has all the ways to reach us.
