Can I configure aggressive minification to remove quotes or shorten keys?

The minifier performs standard JSON minification (whitespace removal only). Aggressive optimizations like unquoting keys or removing optional quotes violate JSON spec and break parsers. The tool prioritizes valid JSON output over maximum compression. Use gzip for further size reduction at transport layer.

Is my JSON data sent to external servers during minification?

No. All minification runs client-side via JavaScript string processing. Your JSON data—whether API payloads, configuration files, or database exports—stays in your browser. Zero network transmission occurs. Critical for security audits and compliance.

What JSON features or file sizes cause problems?

Files exceeding 50MB may hit browser memory limits. JSON with comments (non-standard) must be stripped before minification. Extremely deep nesting (1000+ levels) may cause stack overflow. The tool excels at standard API responses and config files.
