Frequently Asked Questions

How much smaller does code get?+

Typically 30–60% depending on comment density and formatting — every byte saved is bandwidth saved on each page load.

Does minification change how code works?+

No — only whitespace and comments are removed; the logic is untouched. Keep your readable source for development and ship the minified version.

How is this different from a build tool?+

Bundlers like esbuild also rename variables and tree-shake. This tool is for quick one-off minification — a snippet, a legacy file, an email-embedded style block.

Is my code uploaded?+

No — minification runs entirely in your browser. Proprietary code stays on your machine.
