Beautify HTML Code Instantly

Minified or messy HTML is hard to read and debug. Our HTML Formatter properly indents nested elements, handles self-closing tags, and produces clean, readable markup — all client-side with zero server calls.

How to use HTML Code Formatter

  1. Paste or type your input into the editor on the left.
  2. Leave the defaults, or tweak them if the tool exposes options.
  3. The result appears on the right as you type.
  4. Copy the output or download it.

This tool runs in your browser. Your input is not uploaded or stored.

Use it from the API

Everything this page does is also available as a REST endpoint, so you can call HTML Code Formatter from your own code, a script or a CI pipeline.

Bash
curl "https://api.toolsxpo.com/v1/html-formatter" \
  -H "Authorization: Bearer txp_live_YOUR_KEY"

The endpoint returns a JSON envelope ({ ok, data, meta }) and costs 1 credit per successful call. Try it in the playground or browse the full API reference.
