About the Code Minifier

This tool reduces the size of your files by removing comments, collapsing whitespace, and stripping unnecessary characters — without changing how the code behaves.

Supported languages

HTML — preserves content inside <pre>, <textarea>, <script>, and <style>.
CSS — removes comments, collapses whitespace, shortens hex colors.
JavaScript — safe tokenizer that respects strings, template literals and regex literals.
JSON — produces the smallest valid JSON with full validation.
XML — collapses whitespace between tags while preserving CDATA and text content.
SVG — smaller vector graphics that render identically.
SQL — removes comments, collapses whitespace, keeps strings and identifiers intact.

Why minify code?

Smaller files — faster downloads.
Better Core Web Vitals — improved page speed scores.
Lower bandwidth costs — every KB counts.
Cleaner config files — compact data files are easier to embed.
