Frequently Asked Questions

What is the difference between minification and compression?

Minification removes unnecessary characters like whitespace and formatting, while compression uses algorithms like gzip to further reduce file size. Minification is a preprocessing step that makes compression more effective.

Does minification affect JSON functionality?

No, minification only removes formatting and whitespace. The JSON structure and data remain exactly the same, so it will work identically to the original formatted version.

When should I minify JSON files?

Minify JSON files when deploying to production, sending over networks, or when file size matters. Keep formatted versions for development and debugging.

Can I reverse the minification process?

Yes, you can use our JSON Formatter or JSON Beautifier tools to add back formatting and indentation to minified JSON data.
