About — RawTools

What is RawTools?

RawTools is a free, ever-growing collection of browser-based utilities designed for developers and designers. Colour palettes, gradients, converters, formatters, accessibility checkers — everything in one place, nothing in the way.

Every tool runs entirely in your browser. No data leaves your device. No account needed. No tracking cookies. Just open, use, copy the output, and ship.

Why?

Because most online tools are bloated with ads, paywalls, and signup walls. RawTools exists to be the opposite — fast, clean, and focused on the output. You shouldn't need to create an account to convert pixels to rem.

Tools Available

Who Built This?

RawTools is built and maintained by Prakasam Mathaiyan — a designer and developer who got tired of hunting for simple tools across a dozen different websites.

Support

RawTools is free, forever. If it's saved you time, a coffee helps keep the hosting paid and new tools coming.
