Leaner HTML, Faster Pages
HTML files carry surprising amounts of dead weight: comments, indentation, and blank lines that browsers ignore. Removing them makes pages download faster without changing anything visible.
Where minified HTML pays off
- Static sites: Generated pages ship smaller, so first load is faster.
- Templates: Email and server-rendered templates reduce bandwidth per request.
- Edge caching: Smaller payloads fill caches faster and cost less to serve.
- Embeddable widgets: Script-injected HTML loads snappier when lean.
Conservative by design
Aggressive minifiers can rename attributes or collapse meaningful whitespace and break pages. Toolza only removes what is provably optional — comments and formatting whitespace — and leaves script, style, and pre content untouched.
