Remove redundant characters in JSON format data
JSON minification mainly reduces size by removing characters that have no effect on parsing in JSON data, including: spaces, tabs, newlines, carriage returns etc. whitespace characters. These characters only used to improve readability, have no effect on JSON's actual data content.
No. JSON minification only removes whitespace characters, won't change any data content. Minified JSON is completely equivalent to original JSON in data, parsing results completely identical. Minification only optimizes storage and transmission efficiency.
gzip is a general data compression algorithm, can further compress already minified JSON data, usually can achieve 60%-80% compression rate. JSON minification (minify) only removes whitespace characters, while gzip uses algorithm for data compression, both can be combined for best compression effect.
