What is Utils Hub Pro?
Utils Hub Pro is a growing collection of free, browser-based tools built for everyday use. Whether you are a developer needing test data, a writer checking word counts, a student converting units, or just someone who needs a quick answer — there is a tool here for you.
Every tool runs entirely in your browser using JavaScript. Nothing you type is ever sent to a server. No sign-up, no subscription, no usage limits. Just open the tool and use it.
Our Core Values
Privacy First
All processing happens locally in your browser. Tax IDs, text, measurements — none of it ever reaches our servers.
Instant Results
No loading spinners waiting for a server response. Results appear as you type, every time.
Always Free
No paywalls, no premium tiers, no "you've used your 3 free searches today." Every tool, every feature, free.
Works Everywhere
Every tool is fully responsive. Use them on your phone, tablet, or desktop — the experience is the same.
Where We Come From
Utils Hub Pro was created in Portugal and built to serve a global audience. It started as a personal project — a handful of tools that we kept building ourselves in spreadsheets and scripts, because the free alternatives online were either slow, plastered with intrusive ads, or required creating yet another account.
We decided to build something better: a clean, fast, private hub where every tool does exactly what it says, without the friction. The NIF Validator was the first tool — built to solve a real problem for developers testing Portuguese billing systems. The rest grew from there, one tool at a time, based on real needs.
Built for Developers Too
Several tools on Utils Hub Pro are specifically designed with developers and QA teams in mind. The NIF Generator and VAT/GST Generator produce mathematically valid test numbers that pass all format and check-digit validations — letting you seed test databases and test billing flows without using real personal data, which would constitute a GDPR violation.
All generated data is synthetic and safe. Bulk generation (up to 20 at once) and one-click "Copy All" make the workflow fast.

What's Coming Next
Utils Hub Pro is actively maintained and growing. Tools currently in development include a Simple Interest Calculator, a Data Unit Converter (MB/GB/Mbps), and a Case Converter. If there is a tool you would like to see added, we would love to hear from you.
