- What is the difference between beautify and minify?
- Beautify adds line breaks and indentation to make HTML readable (good for debugging, code review, learning). Minify removes whitespace, comments, and redundant quotes to compress HTML (good for production, email templates, embedded HTML in JSON). They're inverse operations — paste minified HTML, beautify to read, edit, then re-minify for deployment.
- Will minification break my HTML?
- If done correctly, no — minification removes only insignificant whitespace and comments. Risks: (1) whitespace inside `<pre>` and `<textarea>` is preserved automatically; (2) inline JavaScript that depends on specific whitespace (rare but possible) could break — review JS-heavy templates after minification; (3) if you used HTML comments as template delimiters (e.g., conditional comments for IE or some email clients), make sure 'preserve conditional comments' is enabled.
- Will beautification change the rendered output?
- Almost never. HTML rendering treats consecutive whitespace as a single space in most contexts, so adding line breaks for readability doesn't change the visual output. Exceptions: content inside `<pre>`, `<textarea>`, `<code>` where whitespace is preserved. The tool handles these correctly.
- Can I beautify HTML with mixed languages (PHP, Twig, Liquid)?
- Yes — the tool preserves template delimiters like `<?php ?>`, `{{ var }}`, `{% if %}`, `<%= %>` as text inside the HTML. They're treated as opaque content. This means beautifying a PHP/Liquid/Twig template won't break the templating; it just formats the surrounding HTML. Caveat: complex inline template logic mixed with HTML attributes (rare) may produce odd indentation.
- Should I commit minified HTML to source control?
- No — keep readable source HTML in your repo. Minify only as a build step (using webpack-html-minifier, htmlmin, or similar). This way: (1) diffs are reviewable, (2) you can edit easily, (3) the build is deterministic. The 'commit beautified, deploy minified' pattern is standard.
- Can this help find unclosed tags or invalid nesting?
- Yes — beautified HTML makes structural problems obvious. If a `</div>` is missing, the indentation cascades incorrectly and you'll spot it immediately. The tool doesn't strictly validate (use a dedicated HTML validator like the W3C validator for that), but the visual structure of beautified output is the fastest way to find malformed nesting.
- Is my HTML data private?
- Yes — completely. All formatting runs in your browser. Your HTML, including any proprietary code, customer data, or internal admin panel markup, never leaves your device. Safe for confidential content. Verify in DevTools → Network: zero outgoing requests.
