HTML Formatter is a free online tool that pretty-prints or minifies HTML so nested tags are readable (or compact) without installing an editor plugin. Paste messy or minified markup, set indent options, and get clean HTML you can copy or download.
Beautify mode focuses on indentation and optional attribute sorting. Minify mode collapses the same document when you want a smaller text payload. Processing stays in your browser for pasted content; Fetch URL uses a short-lived request for public pages.
- Step 1: Add HTML. Paste markup, Import .html / .htm / .txt, load Sample, or Fetch URL for a public page.
- Step 2: Choose Beautify or Minify. Set indent (2 / 4 / Tab) and optional Sort attributes.
- Step 3: Run Format. The primary action switches to Minify when that mode is selected. Review the output pane.
- Step 4: Copy or download. Copy the result or Download when you need a file.
