How to use HTML Minifier

Get the best out of HTML Minifier: every option explained, a worked example, and what to check when the output is not what you expected.

Updated July 31, 2026

What it does

Minify HTML code by removing comments and collapsing whitespace to reduce file size. It runs entirely in your browser — your input never leaves your device.

Options

Every setting this tool exposes, straight from the code that validates it.

OptionTypeDefaultWhat it does
htmltextHTML to minify. Required.

Worked example

Run these settings on the tool page:

  • html: <p>Hello</p>

You get:

<p>Hello</p>

Troubleshooting

  • Nothing happens / the output stays empty. html is required — the tool waits until you provide it.
  • It is slow on very large input. Everything runs in your browser, so speed depends on your device. Very large inputs are best split up, or run through the API where the work happens on our servers.

Automating it

The same logic is available as a REST endpoint, so you can run it from a script, a CI job or your own app.

Bash
curl "https://api.toolsxpo.com/v1/minify-html" \
  -H "Authorization: Bearer $TOOLSXPO_KEY"

It costs 1 credit per successful call. See the full endpoint reference, or try it in the playground.
