Toolinza is a free, professional online tools platform operated by Invoxaco Biz Solutions. Our mission is simple: to give everyone — from professionals and small businesses to students and everyday users — instant access to reliable, privacy-first tools that get real work done, without cost or complication.
What we do
We build and maintain a growing library of 320+ online tools across eight categories: PDF tools, image tools, finance calculators, medical & health calculators, SEO tools, writing & text utilities, everyday calculators and unit converters. Every tool is designed to be fast, accurate and genuinely useful in real-world situations.
Privacy first
We believe your data belongs to you. That is why our PDF and image tools run entirely inside your web browser — your files are never uploaded to a server, never stored and never shared. This client-side approach means your documents stay completely private on your own device.
Built to international standards
Our medical and financial calculators follow internationally recognised formulas and guidelines, including those from the World Health Organization (WHO), the UK's NHS, the US CDC, and standard actuarial and accounting practices. Results are suitable for use across the UK, USA, Canada, Australia, Europe, Africa, Asia and the Middle East.
Who builds Toolinza
Toolinza is built and maintained by the Toolinza Editorial Team at Invoxaco Biz Solutions — a group of software developers, technical writers and editors. We build every tool ourselves rather than licensing them, so we understand exactly how each one works, and we write our guides from hands-on use. Our developers implement the tools and their formulas; our editors research the underlying standards, write the help content, and review each tool and article for accuracy before and after publishing.
Our editorial standards & methodology
We hold every tool and article to the same simple standard: it should be accurate, transparent about how it works, and genuinely useful. In practice that means:
- Cited methods. Each calculator states the recognised formula or standard it uses — for example the Mifflin–St Jeor equation for BMR, WHO categories for BMI, or standard amortization maths for loans — so you can see exactly how a result is produced.
- Review before and after publishing. Tools are tested against known reference values, and content is fact-checked by our editors and updated when standards or best practices change.
- Clear limitations. For health and finance tools we state plainly that results are for general information and are not a substitute for professional advice.
- Privacy by design. Tools run in your browser, so your files and data are never uploaded — a claim we can make because of how the site is actually built.
Our commitment
- Always free — no subscriptions, watermarks or hidden limits.
- Accurate & transparent — standards-based calculations you can trust.
- Accessible everywhere — responsive tools for every device.
- Continuously improving — we add and refine tools based on user needs.
