JSON 코드를 즉시 미니파이 및 압축합니다. 공백, 주석 및 불필요한 문자를 제거하면서 문자열 값은 보존합니다. 100% 클라이언트 사이드.
JSON Minifier is a free online tool that compresses your JSON code by removing unnecessary whitespace, comments, and redundant characters while preserving all data inside string values. Smaller JSON files mean faster API responses, reduced bandwidth usage, and better application performance. All processing happens entirely in your browser — your JSON code is never sent to any server, ensuring complete privacy and security.
Yes, absolutely. Minified JSON is 100% valid JSON. Only unnecessary whitespace and comments are removed — all data, keys, and string values remain intact. You can parse minified JSON with any standard JSON parser.
No. String values are fully preserved, including spaces, tabs, and special characters inside them. Only structural whitespace (outside strings) and comments are removed. Your data integrity is guaranteed.
Typically 30–60% reduction for formatted or indented JSON. The more whitespace, line breaks, and comments your JSON contains, the higher the savings. Well-formatted JSON with nested structures often sees the biggest reductions.
Yes. Use our JSON Formatter tool to beautify minified JSON back into a readable format with proper indentation and line breaks. You can switch between minified and formatted versions anytime.
No. All processing happens entirely in your browser using JavaScript. Your JSON code is never sent to any server or stored anywhere. This ensures complete privacy and security for sensitive data.
Yes. The minifier strips both single-line (//) and multi-line (/* */) comments commonly used in JSONC format, which is supported by many configuration files like tsconfig.json and .eslintrc.json.
Yes, the tool can handle JSON files up to several megabytes. However, extremely large files (10MB+) may take longer to process depending on your device's performance. All processing remains client-side.
Minifying removes all unnecessary whitespace to create the smallest possible JSON file. Formatting (beautifying) adds indentation and line breaks to make JSON human-readable. Use minification for production and formatting for development/debugging.
