About MinifyTools

MinifyTools was built out of the same frustration that builds most small utilities: the existing options were either buried inside a larger tool you didn't need, required an account to use, or — worse — uploaded your code to a server you knew nothing about.

The goal was simple: a fast, focused minifier that handles HTML, CSS, and JavaScript properly, runs entirely in your browser, and doesn't require a login or collect anything from you.

MinifyTools minifies and beautifies HTML, CSS, and JavaScript instantly in your browser:

• HTML minifier — removes comments, whitespace, and redundant markup. Inline <style> and <script> blocks are minified too.
• CSS minifier — strips comments, collapses whitespace, and optimises selectors without touching your values.
• JavaScript minifier — powered by Terser, the same engine used by webpack and Vite. Dead code removal, variable mangling, full ES2020+ support.

All processing runs locally. Your code never reaches a server.
