Frequently asked questions
Does minifying change the data?
No. Only unnecessary whitespace and line breaks are removed; the values and structure stay intact.
How much smaller will my file get?
It depends on the original indentation, but a well-indented file often shrinks by 10 to 30 percent.
Can I reformat the minified JSON later?
Yes. Minifying is reversible: use the JSON formatter to re-indent the result whenever you need to.
Is my data uploaded anywhere?
No, everything happens locally in your browser.
