Free Online Utility Tools

Utility tools handle the small conversions that don't fit neatly into image or document categories — things like translating a color from one notation to another so it works in the right place. A designer hands off an RGB value, a stylesheet expects a HEX code, and you need to convert between the two without opening a separate app or doing the arithmetic yourself. These tools solve that in a single step.

Every tool here is completely free and runs entirely inside your browser tab using WebAssembly, so nothing is ever uploaded to a server. There's no signup, no account, and no install — your data never leaves your device, which means no waiting on a queue and nothing of yours sitting on someone else's storage afterward.

Pick the tool that matches what you're trying to convert below and get the result instantly — privately and for free.

Most online conversion tools work by sending your input to a server, processing it there, and sending the result back. The utility tools here skip that step entirely — the conversion logic runs directly in your browser tab, so nothing about what you type or pick ever crosses the network. Nothing is stored, logged, or cached on our end — once you close the tab, there's no record of what you converted.
