About

I'm Arun. I build every tool on this site myself — the code, the calculations, and the writing. I have an MBA in Finance and Marketing, which is where the interest in salary structure and tax comes from.

I built these because I hit the problems myself. I wanted to know what a job offer actually paid per month. I wanted to resize an image without making an account. Every tool I found wanted a login or a subscription first, so I wrote my own and put them here.

Everything is free. No signup, no watermark, no catch. There is no paid tier and nothing is held back.

Nothing you type leaves your browser. Every calculation runs on your device — your salary, your rent, your images are never uploaded anywhere, because there is no server doing the work. That is true of every tool here, and it is the point of the site. It also means there are no accounts, since there is nothing I need from you to make the tools work.

If you need a tool that doesn't exist yet, email me at powerfulextensions@gmail.com and I'll try to build it. Same address for bugs or a number that looks wrong. It'll be simple and it'll be free.
