Foire aux questions
Why should I minify JSON?
Minifying JSON removes white space and line breaks, reducing payload bandwidth by 10% to 30% for high-traffic REST APIs and databases.
Does minification alter JSON values?
No. Minification strictly removes non-functional whitespace outside of string values without modifying keys or values.
