About JSON Prettify

JSON Prettify is a free, fast, and privacy-focused online tool for formatting, validating, and minifying JSON data. It was built to solve a simple problem: making JSON readable without any hassle.

Why JSON Prettify?

Developers deal with JSON every day — from API responses and config files to database exports and log files. Reading unformatted JSON is painful. JSON Prettify makes it instant and easy.

Key Principles

  • Privacy First — All processing happens in your browser. Your data is never sent to any server.
  • No Signup Required — Just paste and format. No accounts, no emails, no tracking.
  • Free Forever — This tool is free to use with no limits.
  • Fast & Lightweight — Static site with zero dependencies. Loads in milliseconds.

How It's Built
