No black box

How this tool handles the input

Formatting uses a dedicated HTML parser. Minification removes comments and layout whitespace while preserving known whitespace-sensitive blocks.

Before you start

What you need

HTML markup and the presentation mode required for the output.

What you get

What the page gives back

Formatted or minified .html text ready to review and download.

Keep in mind

Use the result responsibly

This tool is not an HTML sanitizer. Never inject untrusted output into a page without a trusted sanitization policy.

Practical uses

Where this tool earns its place

  1. Clean a component template for review.
  2. Minify a small static snippet.
  3. Check whether malformed markup can be parsed.

Verified data boundary

Source text stays on this page.

The published contract marks these tools as client-only processing. Nirmion uses the API only to confirm that this workspace is enabled in MySQL; source values and results are not sent to Flask.
