Paste minified HTML and format it for readability. Helps when debugging markup.
What is this tool?
HTML from CMS exports, templates, or minifiers often arrives as one long line or with inconsistent indentation. The HTML Formatter pretty-prints HTML with logical indentation and line breaks. Paste minified or messy markup and get readable output. Nested elements indent properly; attributes can be aligned for clarity. The result is easier to read, diff, and edit. Some formatters also minify—remove whitespace for smaller file size. This tool focuses on formatting for readability.
Formatting parses the HTML (or XHTML) and reformats it with consistent indentation. Self-closing tags, attributes, and nested structures are handled. Invalid markup may cause parsing issues; the formatter does its best with well-formed input. For debugging markup, inspecting CMS output, or cleaning up pasted HTML, it saves time. No need to manually add line breaks and indents.
All processing runs client-side. Your HTML stays on your device. Paste large documents or small fragments. The tool doesn't execute scripts or follow links—it only reformats the markup. For security-sensitive content, that's reassuring. For quick cleanup, it's convenient.
Use it when inheriting minified HTML, when comparing two versions of a page, or when preparing markup for documentation. For production, many teams use build tools that minify HTML; this formatter fills the gap when you need a quick format without a full pipeline.
Handy for developers and anyone who works with raw HTML.
