Qu'est-ce que Formateur HTML ?
An HTML formatter takes messy, minified, or inconsistently indented markup and rewrites it with clean, predictable indentation so it is easy to read and edit. It can also do the reverse — minify HTML by stripping comments and whitespace for production. Whether you have pasted a single-line blob from "view source" or generated markup from a CMS, the formatter makes the structure visible at a glance.
This tool runs entirely in your browser. Switch between Beautify (with 2-space, 4-space, or tab indentation) and Minify, paste your HTML, and copy the result. It is ideal for cleaning up scraped markup, untangling generated email HTML, preparing a snippet for documentation, or shrinking output before shipping.
Cas d'utilisation
Voici les façons les plus courantes d'utiliser Formateur HTML au quotidien.
Cleaning Up Scraped or Generated HTML
Markup copied from "view source", a CMS, or a page builder is often one long line or wildly inconsistent. Beautify it to reveal the nesting so you can find and edit the part you need.
Debugging Layout Issues
A mis-nested or unclosed tag is far easier to spot in properly indented HTML. Format the markup and scan the indentation — a tag that does not line up usually points straight to the bug.
Preparing Code for Docs or Snippets
When pasting HTML into documentation, a blog post, or a code review, clean indentation makes it readable. Format first, then copy.
Minifying for Production
Switch to Minify to strip comments and collapse whitespace before inlining a fragment or shipping a template, shaving bytes off the page.
Exemples
Beautifying a one-liner
A single-line blob becomes a readable, indented tree.
<div class="card"><h2>Title</h2><p>Text</p></div> <div class="card">
<h2>Title</h2>
<p>Text</p>
</div> Minifying markup
Switch to Minify to collapse whitespace and drop comments.

Conseils d'utilisation de Formateur HTML
- Pick the indentation that matches your project — 2 spaces is the most common web convention, but tabs and 4 spaces are options.
- Beautify is great for reading; Minify is great for shipping. Keep your source formatted and minify as a final step.
- Simple inline elements like <p>text</p> are kept on one line so the output stays compact and readable.
- If formatting looks off, check your source for an unclosed tag — the formatter follows the structure you give it.
Foire aux questions
Does formatting change my HTML output?
Beautifying only adds indentation and line breaks, which browsers ignore between block elements — your page renders the same. Be mindful that whitespace can matter inside <pre> and around inline elements in rare cases.
Is my HTML sent to a server?
No. Both beautify and minify run locally in your browser. Your markup is never uploaded or stored.
Can it fix broken or unclosed tags?
No — it formats the structure you give it rather than repairing it. In fact, clean indentation often makes a missing closing tag obvious so you can fix it yourself.
What indentation options are there?
Two spaces, four spaces, or tabs for beautifying. Choose whichever matches your codebase's style.
Does it handle inline scripts and styles?
It indents the surrounding HTML structure. The contents of <script> and <style> blocks are preserved as-is rather than reformatted — use the CSS Minifier or a JS formatter for those.
