Frequently Asked Questions

Will it change coordinates?

The tool parses and serializes the JSON without deliberately changing coordinate values. Validate the output in your map workflow before replacing the source.

How much space does it save?

Savings depend on how much indentation and whitespace the source contains. Already minified files may become only slightly smaller.
