Frequently asked questions
Does minifying change my data?
No. Minification removes insignificant whitespace only. Parsed values stay the same.
What do the byte counts mean?
Original and minified sizes use UTF-8 byte length—useful for estimating payload size over the wire.
Is my JSON uploaded?
No. Minification runs locally in your browser.
