JSON Minifier
Strips every byte of whitespace outside strings. The result re-parses to the identical value — whitespace inside strings is untouched.
A little guidance. A better result.
How to use JSON Minifier
Parse and compact JSON for smaller text output. Very large numbers can lose precision.
Prepare your input
Paste valid JSON.
Use the workspace
Inspect the compact output.
Check your result
Check it parses correctly in your destination.
Know the limits
Parsing can change numeric representation or lose precision for large numbers; minification is not a byte-preserving edit.
