About TechCalcHub
"I built TechCalcHub because I was tired of doing the same calculations over and over again. Now I want to share these tools with everyone."
Our Story
Hi there! I'm a full-stack developer who spends way too much time downloading large files, comparing monitor specs, and resizing images. After calculating download times for the hundredth time, I thought: "Why isn't there a simple, fast tool for this?"
That's how TechCalcHub was born. What started as a personal project quickly grew into a collection of useful calculators that I use daily — and now you can too.
