Minify Less

Paste your Less and get a minified version with whitespace and comments removed to reduce file size and speed up page loads, with the bytes saved (gzip too) shown. Less is minified by whitespace alone, so every rule stays.

The whole process is client-side — nothing is uploaded and there's no account — so you can minify assets privately and instantly, drop several files for a ZIP, and compare input and output in Code Compare to check nothing changed.

Less Minifier — frequently asked questions

How do I minify Less?
Paste your Less into the left panel and the minified result appears on the right instantly. Copy it or download it as a file.
How is Less minified?
Less keeps its variables, mixins and nesting, so it is minified by whitespace alone: comments out (except /*! ones), spaces and line breaks collapsed, final semicolons dropped. Every rule stays as written, and brace, string and comment problems are reported with their line.
Is my code uploaded anywhere?
No. Formatting and minifying run entirely in your browser with JavaScript — your code never leaves your device. It's free with no sign-up.
