Hey, I'm Abhijit Chowdhury — the one who built this.

God of Tools started because I was tired of uploading my files to random websites just to compress an image or split a PDF. Every tool out there either makes you wait, shows you ads, or quietly sends your files to a server somewhere. That didn't sit right with me.

So I built this — a set of tools that do the work entirely inside your browser. Your files never leave your device. No account needed, no upload bar, no waiting. Just open, use, done.

I'm one person maintaining this in my spare time. If something's broken, a tool you need is missing, or you just want to say hello — I actually read my email.
