About ConverterHub
A free platform of 25+ online tools built to help students, professionals, surveyors and everyday users — without paywalls, without sign-ups, without compromising your privacy.
🎯 Our Mission
ConverterHub was built with one goal: give everyone access to powerful, professional-grade tools — no subscriptions, no hidden fees, no watermarks on your output.
Too many useful tools are locked behind paywalls or require account registration just to convert a file. We believe that should change. Every tool on this site is free to use, works directly in your browser, and keeps your data private because nothing ever leaves your device.
👤 Who Built This
ConverterHub is an independent project built and maintained by Adebayo (Oluwafemi Adebayo Okedele), a solo web developer based in Nigeria with a background in web development and GIS/surveying tools.
The coordinate conversion tools — particularly the Nigerian NNO, Minna Datum and UTM systems — were built with real surveying professionals in mind, tested against Mobile Topographer Pro and SivanDesign.
🔧 Our Tools
Every tool runs entirely in your browser. No files are ever sent to any server.
🌍 Built for Nigeria, Used Worldwide
Our coordinate converter supports the Minna Datum (1996 and 2008), all three Nigeria belts (West, Mid and East), NNO local origins and UTM Zones 31N and 32N — making it one of the most complete free Nigerian surveying tools available online.
🛡️ Privacy & Transparency
All file processing and coordinate calculations happen directly in your browser. We do not collect, store or transmit your files or coordinate data to any server. This site uses Google Analytics and Google AdSense — see our Privacy Policy for full details.
