The minifier extension for TYPO3 CMS (EXT:min) reduces the output of TYPO3 in several ways:

  • it minifies CSS and JS assets (TYPO3 "just" gzip them), which may safe you additional 60% of file size

  • and it also compresses the HTML output for every page, to one single line (formerly known as "tinysource")

EXT:min uses the great matthiasmullie/minify package.


  • Additional minification of JS and CSS assets (including files in AssetCollector)

  • HTML output compression

  • Highly configurable

  • Full composer support

  • Alternative TER version (with minify library included)

Roadmap / Missing Features

  • Provide unit tests, to ensure correct minification results
