HTML Tools

Browser-native utilities for developers. No installs, no servers, no tracking.

Homepage HTML Tools

HTML Tools is a collection of browser-native developer utilities — everything runs client-side with no backend, no installs, and no tracking. Open a tool, use it, close the tab.

I kept running into situations where I needed a quick utility — format some JSON, merge a couple of PDFs, compress an image — and every online option was either slow, ad-heavy, or required an account. I knew what I wanted, but building 40+ tools from scratch felt out of reach. With AI assistance, I was able to ship this in a way that simply wasn’t practical for me before. Each tool is a standalone page: no framework overhead, no shared state, just the utility doing its job.
