Online code minifier

Minify HTML, CSS, JavaScript, and JSON to reduce payload size and clean up production-ready output.

Minified output

Why minify code?

Faster loading

Removing comments, whitespace, and redundant characters reduces transfer size and shortens download time.

Lower bandwidth cost

Smaller assets reduce the amount of data a site needs to deliver at scale.

Less parsing work

Browsers still have to parse the response. Shorter payloads can reduce that work on the client.

Minification vs obfuscation vs transfer compression

Minification

Removes unnecessary characters without intentionally changing the logic structure.

Obfuscation

Makes code harder for humans to read by renaming identifiers or reshaping logic.

Gzip / Brotli

Transport-layer compression reduces payload size in transit and works best when combined with already minified code.

Tree shaking

Eliminates unused modules during the build step instead of only shrinking the final emitted code.

Frequently asked questions

Can minified code be made readable again?

Formatting tools can restore whitespace and line breaks, but comments and original variable intent are often lost.

Is this tool safe for private code?

The transformation runs in the browser, so the code does not need to be uploaded to a remote service just to be minified.

Can minification ever break code?

It usually should not, but malformed input or edge cases can still create output that deserves testing before production use.
