Pro tips

Get better results with these expert suggestions:

Safe for proprietary HTML

Client-side minification means your proprietary HTML structures, trade secrets embedded in source, and client data never leave your browser. Ideal for NDA-protected work.

Works on slow or metered connections

Because processing is local, minification is instant regardless of your internet speed. There are no files to upload or results to download.

Same result every time

Client-side minification produces deterministic output. The same input always produces the same minified HTML.
