Questions
How much does minifying actually save?
For indented JSON, typically 15-30% before compression. The tool shows the exact saving for your document. Note that gzip or brotli already compress repeated whitespace very effectively, so the saving over the wire is much smaller than the raw byte difference suggests.
Is minified JSON still valid?
Yes. Whitespace between tokens carries no meaning in JSON, so removing it produces an identical document to any parser.
