Frequently Asked Questions

What is the difference between minify and beautify?

Minify removes non-essential characters for smaller files; beautify adds structure for readability.

Can minification break code?

Well-formed code should remain equivalent, but always test transformed output.

Should I minify before deployment?

Usually yes for web assets, especially when paired with compression and caching.

Can I beautify third-party minified bundles?

Yes. Beautification helps inspection even if variable names remain compressed.

How much file size does minification save?

Typically 20–40% for CSS and HTML, and 10–30% for JavaScript with comments and generous whitespace.

Can I minify JSON?

Yes—select JSON to remove whitespace from API payloads or config files, producing a single-line string.

Does beautification recover original variable names?

No—beautification restores formatting only. Name-mangled identifiers from production bundles remain shortened.

Should I minify code before or after bundling?

Modern bundlers minify during production builds. Use this tool for one-off snippets or debugging minified third-party code.

Is my source code uploaded to a server?

No. Minification and beautification run entirely in your browser.
