Hello, and welcome
I am Mirza Nayab, the writer and editor behind ZetTool. I believe everyday tasks should feel less frustrating: checking a loan EMI, working out a fuel budget, counting a paragraph or two, shrinking an image, or writing a number in words. ZetTool brings these focused tools together so you get an answer and move on.
What I write about
Mostly practical things — how our calculators work, honest guides to conversions, and walkthroughs of the browser-based PDF and image tools. Every article is designed to be genuinely useful, plain-spoken, and free of jargon.
