JS Minifier
Minify JavaScript by removing comments and whitespace. Preserves strings, template literals, and regex patterns.
What is JavaScript Minification?
JavaScript minification strips comments, whitespace, and unnecessary characters from your code to reduce file size. Unlike uglification (which also renames variables to shorter names), basic minification preserves all identifiers, making the output easier to debug. Minified JS files download faster and parse quicker in the browser, improving page load performance โ especially important on mobile networks.
How to Minify JavaScript
Paste your JavaScript code into the input panel. The tool safely handles strings, template literals, and regex patterns.
The minifier removes comments (single-line and block), collapses whitespace, and optionally removes trailing semicolons.
View the size savings and copy the minified output. The tool preserves all string contents and regular expressions exactly.
