HTML Minifier

Reduce HTML size by removing unnecessary whitespace and formatting while preserving valid markup.

HTML input

Paste a full document, component template, or partial snippet.

Limit 5 MB

Remove commentsRemoves regular HTML comments from the output.Collapse whitespaceReplaces ordinary runs of spaces and line breaks with one space.Remove whitespace between tagsCompacts adjacent tags and can affect inline-element spacing.Preserve conditional commentsKeeps legacy conditional comment blocks when comments are removed.Preserve template syntaxProtects common interpolation and server-template expressions.Preserve pre/code/textarea whitespaceKeeps whitespace-sensitive element content unchanged.Preserve Angular/template attributesKeeps bindings, events, directives, custom, data, and ARIA attributes verbatim.

Review visual output after whitespace changes. Spaces between inline elements can affect rendered text and layout.

Minified HTML

Compact text output with size savings and preservation warnings.

Ready to minify HTML

Paste HTML or load a sample, choose conservative options, then minify.

HTML stays inert: scripts and inline event handlers are never executed.

HTML Minification Guide

Reduce HTML source size without executing markup

Compact full documents and reusable snippets locally, then review the savings and warnings before using the result.

What is HTML minification?

HTML minification removes comments, indentation, line breaks, and redundant spacing that browsers usually do not need to parse a page.

HTML Formatter vs HTML Minifier

An HTML Formatter expands markup for human review. An HTML Minifier compacts markup for smaller files and transfer payloads.

How HTML minification reduces page size

Removing repeated whitespace and development comments reduces raw document bytes. Compression can reduce transfer size further in production.

Common minification risks

Whitespace between inline elements can be visible, comments may support build tools, and framework templates may assign meaning to source formatting.

Preserving template syntax

Common interpolation blocks and Angular-style attributes are preserved as inert source text. The tool does not evaluate expressions or framework code.

Whitespace-sensitive content

Content inside pre, code, and textarea stays unchanged by default. Script and style blocks are also protected and never executed.

HTML Minifier FAQ

Does HTML minification change functionality?

Conservative minification usually preserves behavior, but visible spaces between inline elements can matter. Always review and test the result.

What is the difference between formatting and minifying HTML?

Formatting adds indentation for readability. Minifying removes unnecessary formatting to create compact output.

Does this tool remove comments?

Yes, when Remove comments is selected. Conditional comments can be preserved separately.

Will Angular or template syntax still work?

Common template expressions and framework attributes are preserved by default, but framework-specific compilation is not performed.

Can I minify partial HTML snippets?

Yes. Full documents, components, custom elements, and partial fragments are supported without adding a document wrapper.

Does this tool upload my HTML?

No. Minification, warnings, copying, and downloads run locally in your browser.
