About JSON Minify & Beautify
Paste JSON and switch it between two shapes: squeezed down to a single compact line, or beautified with clean, consistent indentation you can actually read. It is handy for shrinking a payload before you send it, or for making a minified blob legible again.
The formatting runs entirely in your browser, so the JSON you paste stays on your own device and is never uploaded. It is free, needs no account, and puts no limit on how much you convert.
Frequently asked questions
- Is it free, and do I need to sign up?
- It is free with no sign-up and no account. You can minify and beautify as much JSON as you want, with no usage limits and nothing to install.
- Does my JSON get uploaded to a server?
- No. Everything happens in your browser, so the JSON you paste never leaves your device. That is useful when a payload contains data you would rather not send anywhere.
- How do I use it?
- Paste your JSON into the box and choose minify to collapse it onto one line, or beautify to expand it with indentation. You can then copy the result straight out.
- What does minifying actually remove?
- Minifying strips the spaces, line breaks, and indentation between the data, leaving the JSON on a single line. The data itself is untouched; it is the same JSON, just without the whitespace that makes it larger.
- What if my JSON has an error in it?
- The tool works on valid JSON, so a missing bracket, a stray comma, or an unquoted key will stop it from formatting until that is fixed. It is a formatter, not a repair tool that guesses at what broken JSON was meant to be.
