Questions

Does it validate against my schema?

It checks syntax only (queries, mutations, fragments and SDL schemas). No schema or endpoint is needed.

Is anything sent to a server?

No. Formatting uses the reference graphql-js parser in your browser.

What does minify do?

It strips whitespace, commas and comments that GraphQL ignores, keeping the query identical in meaning.
