HTML Minifier
Minify HTML online with conservative whitespace and comment cleanup while preserving scripts, styles, and whitespace-sensitive content.
Tool workspace
The interactive tool requires JavaScript.
Instructions
2. Click “Minify HTML” to generate a conservative browser-local result.
3. Review whitespace-sensitive text, scripts, styles, and template syntax before copying the output into your target system.
Paste an HTML fragment or page source and generate compact output for examples, templates, email snippets, or static page review. Processing stays in your browser and the HTML is not rendered or executed.
HTML minifying can shorten tags, attributes, layout whitespace between tags, and ordinary comments, but it should not blindly rewrite text nodes, script, style, pre, or textarea content. This tool uses a conservative strategy: it preserves those sensitive areas, removes ordinary comments, and keeps conditional or bang-preserved comments to avoid accidental semantic changes.
What this HTML Minifier changes
The tool compresses repeated whitespace outside quotes in tags and attributes, removes obvious layout whitespace between tags, and drops ordinary HTML comments. It does not execute the page, load resources, upload source code, or render the HTML preview.
Why the minifying is conservative
HTML whitespace can affect visible copy, inline elements, template placeholders, email layouts, or signed snippets. To reduce risk, the tool preserves text nodes and keeps script, style, pre, and textarea content unchanged.
What to review after minifying
If your HTML includes template syntax, inline scripts, CSS, SVG, email-client compatibility code, conditional comments, or whitespace-dependent copy, test the output in the target environment. Minifying is not a build pipeline, XSS audit, or accessibility review.
