Minify JSON by removing whitespace.
Keep or share the finished result
Copy or share after running the tool. Saved tools and settings stay in this browser.
What would you like to do next?
Minify your JSON
Paste JSON above to strip out every space and line break, producing the smallest valid form for sending over a network or storing compactly. The input is parsed first, so if it is not valid JSON you get an error instead of broken output. The whole process runs in your browser, keeping your data private.
Minify vs beautify
Minifying removes whitespace to save size, while beautifying adds it back for reading. Use the JSON formatter when you need readable, indented output.
Frequently asked questions
Does minifying change my data?
No. It only removes whitespace. The keys, values and structure of the JSON stay exactly the same.
What if my JSON is invalid?
The tool parses the input first, so invalid JSON produces an error rather than incorrect output.
