What this tool does

This HTML formatter pretty-prints pasted markup for easier review, debugging, documentation, and cleanup without rendering or uploading the HTML.

Common use cases

Pretty-print pasted HTML snippets, templates, and CMS markup for easier review and debugging.

Use HTML Formatter when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.

How to use it

  1. Paste compact or messy HTML into the input box.
  2. Review the indented output and tag count.
  3. If you need a smaller version next, open HTML Minifier and continue the workflow there.
  4. Copy the formatted HTML for code review, CMS cleanup, or documentation.

Example workflow

Paste the HTML snippet, template, or tag block you need to inspect. Format, minify, encode, decode, or convert it as plain text, then copy the cleaned output into your editor, CMS, documentation, or QA note.

Privacy note

Client-side only: pasted HTML is treated as text, formatted in your browser, and is not uploaded or rendered.

FAQ

Does this HTML formatter render my HTML?

No. Pasted HTML is treated as text and shown safely in a text output area rather than rendered into the page.

Can it format full documents and snippets?

Yes. It works for common pasted HTML snippets, templates, and simple full-page markup within the browser text limit.

Is my HTML uploaded?

No. Formatting runs locally in your browser.
