Frequently Asked Questions

Is my data secure?

Absolutely! This tool runs entirely in your browser. Your JSON data never leaves your computer and is not sent to any server. We don't store or process your data on any backend systems.

What is the maximum file size I can process?

There are no artificial limits. The only constraint is your browser's memory capacity. For most modern browsers, you can process JSON files up to several hundred megabytes.

Does compression affect my data?

No, compression only removes unnecessary whitespace and formatting. The actual data content remains unchanged. You can always reformat the compressed JSON without losing any information.

Can I compress minified JSON?

If your JSON is already minified, there won't be any additional compression from this tool. This tool specifically removes whitespace and formatting, which has already been done in minified JSON.

Is this tool completely free?

Yes, this JSON compressor is 100% free to use with no limitations, signups, or subscriptions. You can use it as much as you need for personal or commercial projects.
