HTML Minifier

Minify HTML by removing unnecessary whitespace.

About HTML Minifier

Every byte counts on landing pages and email templates. Our HTML Minifier removes unnecessary whitespace and comments from markup to produce smaller files for production - while keeping semantics intact. Processing is local, so unreleased campaigns, client HTML, and internal dashboards stay private. Compare before/after sizes to validate gains, then deploy minified HTML behind your CDN. Pair with CSS and JS minifiers when you need a quick performance pass before launch.
