# x-www-form-urlencoded to JSON Converter

> A free Fabreco Studio developer tool that converts raw x-www-form-urlencoded data, query strings, and complete URLs into structured JSON.

The browser interface performs conversion entirely on the user's device. The public API is stateless and does not persist input, but API input is transmitted to the server for processing.
