About Code Minifier
Minify code to reduce file size. Remove whitespace and comments from code.
Code Minifier strips the parts of a file that browsers do not need: extra whitespace, indentation, line breaks, commented out explanations and, where safe, redundant punctuation. The result loads faster, costs less bandwidth and is harder to skim casually, which is why minified bundles ship in production. Paste CSS, JavaScript, HTML or JSON, choose which transformations to apply, and copy the compact output along with the percentage saved. Running the tool twice does not break the result, and the original stays in the editor so you can compare. Code Minifier is free, runs in your browser and never uploads your source.
How to Use Code Minifier
- Paste your code, markup or configuration into the editor.
- Choose the output format or options offered.
- The formatted result updates live.
- Copy or download the finished code.
Key Features
- Clean, consistently formatted output ready to paste.
- Supports the common formats used in web development.
- One-click copy and download — no build step required.
Frequently Asked Questions
Is it safe to minify JavaScript with Code Minifier?
It is safe for whitespace and comment removal, which is exactly what the tool focuses on. It does not rename variables, rewrite logic or fold expressions, so the behaviour of your script stays identical while the file shrinks. Always keep the original source in version control, test the minified copy in the browser and run the tool again after every manual edit.
Is Code Minifier free to use?
Yes. Code Minifier is completely free with unlimited use — no account, download or payment required.
Is my data uploaded to a server?
No. Code Minifier runs entirely in your browser. Your inputs are never sent to our servers or stored anywhere.
Does Code Minifier work on mobile?
Yes. The interface is fully responsive and works in any modern browser on Android, iPhone, tablets and desktops.
