What is a JSON minifier?▼
A JSON minifier is a tool that compresses JSON data by removing unnecessary whitespace, line breaks, and indentation. This reduces file size without changing the actual data or structure.

JSON minification removes formatting characters that are only useful for human readability. By eliminating spaces and newlines, JSON file size can often be reduced by 30–60%.
Does minifying JSON change the data?▼
No. JSON minification does not modify keys, values, or structure. The data remains exactly the same, only the formatting is removed.
When should I minify JSON?▼
JSON should be minified before sending data over networks, deploying APIs, or serving JSON files in production environments to reduce bandwidth usage and improve performance.
