What is SpeeJax?
SpeeJax offers free, browser-based tools for website optimization. You can minify HTML, CSS, and JavaScript, clean unused CSS, compress and convert images, optimize SVGs, and generate helpful performance markup like lazy-load and preload tags. Everything runs locally in your browser, so files stay on your device and you do not need to sign up or upload anything to a server. It is built for quick, practical speed improvements without extra setup.
