Does minifying change the data?

No. Only whitespace between tokens is removed; keys, strings and numbers are untouched.

How much smaller will it be?

Typically 20–40% for pretty-printed JSON. The footer shows the size before and after.

Can I go back to readable JSON?

Yes — press Beautify at any time.
