How to use the HTML formatter
- Paste raw HTML into the editor pane on the left side of the workspace.
- Use Format to beautify nested tags with readable indentation.
- Use Validate to check whether the current markup has mismatched or unclosed tags.
- Use Minify when you need compact HTML for embeds, templates, or inline snippets.
- Use Copy Output after a successful action to move the normalized markup into your app, docs, or CMS.
HTML formatter examples
- Prettify a one-line HTML snippet before reviewing nested sections, headings, and lists.
- Validate copied markup from a CMS or email template and locate mismatched closing tags.
- Minify a cleaned HTML block before embedding it into a config field or static template.
What this HTML formatter does
This HTML formatter gives you a browser-based workspace for beautifying, validating, and minifying HTML in one place. Instead of switching between an editor, a formatter, and a separate validator, you can keep the raw markup, normalized output, and status feedback visible together.
That makes it useful for cleaning up snippets, reviewing template markup, checking copied embed code, and preparing HTML before you paste it into a project or content system.
When to format, validate, or minify HTML
Use Format when you want readable indentation and a clearer structure for nested markup. Use Validate when you mainly need to check for mismatched or missing closing tags before you continue editing. Use Minify when you want the shortest possible HTML output for storage, transport, or inline use.
All three actions work from the same editor state, which means you can move between cleanup, verification, and export without leaving the current workspace.
HTML formatter FAQs
Does this HTML formatter validate markup too?
Yes. Validate checks the current HTML for common structural issues such as mismatched or unclosed tags and reports an invalid state when it finds one.
Can I minify HTML with this tool?
Yes. Use Minify to generate compact HTML output with unnecessary whitespace reduced between tags.
What happens when the HTML is invalid?
The workspace shows an invalid state and error details instead of leaving a misleading successful output in place.
