HTML Minifier — Free Online Minifier

HTML Minifier strips out whitespace, comments and other redundancy to shrink your HTML for production. It runs entirely in your browser, so nothing you enter is uploaded to a server. Free to use, with no signup and no watermark.

How to use HTML Minifier

1. Paste your HTML.
2. Run the minifier.
3. Copy the compressed output and check how much you saved.

Frequently asked questions

Will minifying break my code?

It preserves behaviour while removing whitespace and comments, but always test the minified output before deploying.

How much smaller will my file get?

Typically 20-60% before gzip, depending on how many comments and how much whitespace the original had.

Can I reverse it?

Run the output through a formatter to make it readable again, though original comments cannot be recovered.
