Frequently asked questions

Does minification break my code?▼

No — the minifier only removes whitespace and comments. Functionality is preserved.

What is the difference between minify and beautify?▼

Minify compresses code to reduce file size. Beautify formats it with indentation for readability.

Is JSON validation included?▼

Yes — if your JSON is invalid, the tool will report the exact error.

Can I minify large files?▼

Files up to 1 MB work well. For larger files, use a CLI tool like UglifyJS or cssnano.
