About The HTML Minifier

This free online HTML Minifier compresses HTML snippets by removing unnecessary whitespace between tags and, when selected, regular HTML comments. It also minifies inline <style> blocks so small page fragments, templates, and email snippets are easier to copy into production or test payloads.

Processing runs in your browser. The minifier preserves the contents of <script>, <pre>, and <textarea> blocks because whitespace in those areas can affect behavior or visible output.

How to Minify HTML Online

1. Paste your markup into HTML input.
2. Leave Remove HTML comments when minifying checked when ordinary comments should be removed.
3. Click Minify to create compact HTML output.
4. Use Prettify when you want readable indentation for review instead.
5. Click Copy Output to reuse the result.

Choosing Options Correctly

Remove HTML comments when minifying:
- Leave it ON for normal production snippets where comments are not needed.
- Turn it OFF when comments are part of a template workflow, documentation, or conditional markup you want to keep.
- Conditional comments are preserved to avoid breaking older compatibility patterns.

Minify vs Prettify:
- Use Minify when you want smaller copied output.
- Use Prettify when you need to inspect or clean up markup before editing.
- Test important output in a browser or build pipeline before deploying it.

Common Use Cases

• Compress a small HTML component before pasting it into a CMS, email template, or config field.
• Clean up copied markup by switching between minified and readable forms.
• Minify simple static fragments that include inline CSS.
• Prepare sanitized examples for tickets, documentation, or testing.

Quick FAQ

Is this the same as a build-tool HTML minifier?
No. It is a quick browser tool and may not apply the same transforms as a production build pipeline.

Will it change my JavaScript?
It may affect inline script text if aggressive options are used. Review output before replacing source files.

Why does the output still wrap in the panel?
The display panel can wrap long lines visually even when the copied minified text has fewer line breaks.

Is my HTML uploaded?
No. Minification is designed to run in the browser.
