JSON Minifier
Minify JSON data online to remove whitespace and shrink file size. Free and runs in your browser.
JSON Formatting and Validation
JSON is a popular format for APIs and configuration because it’s lightweight and easy to parse. The downside is that large JSON payloads can get hard to read fast—especially when everything is on one line.
A formatter makes JSON easier to work with by applying consistent indentation and line breaks. Your data doesn’t change—only the whitespace—so it’s safer to review, debug, and share.
How do I minify JSON?+
Paste your JSON into the input. The minified version appears automatically; copy or download it.
What does minifying do?+
It removes unnecessary whitespace and comments so the file is smaller and loads faster.
Is my code uploaded anywhere?+
No. Minification runs entirely in your browser, so your code stays on your device.
