About JSON Minify
Minifying keeps the data identical but strips formatting, which reduces size for APIs, config files and storage. Invalid JSON is reported with an error. Everything runs locally in your browser, so your data is never uploaded.
Example
Input
{
"a": 1,
"b": [1, 2]
}Result
{"a":1,"b":[1,2]}FAQ
Does minifying change the data?
No. Only whitespace is removed.
Are my files uploaded to a server?
No. Everything runs in your browser; your files and text never leave your device.
Is it free? Do I need an account?
The tool is free and needs no registration.
Does it work on a phone?
Yes, in modern desktop and mobile browsers; large files depend on your device power.
