How Do You Format HTML Online?
To format HTML online, paste your code into the HTML input box, or upload an .html file or drop it onto the box. Pick an indentation (2 spaces, 4 spaces or Tab), then click Beautify HTML or press Ctrl + Enter. Clean, indented HTML appears in the Result box, ready to copy or download. To make the code smaller instead, click Minify HTML.
HTML copied from a CMS, a page builder, an email builder or a minified production file often arrives as one long line with no indentation. That makes it hard to read, debug and review. An HTML formatter, also called an HTML beautifier or pretty printer, rebuilds the indentation so every nested tag sits on its own line and you can see the structure of the page at a glance. When the code is ready to publish, a minifier does the opposite and strips out the extra whitespace.
Everything runs on your own device. Beautifying uses the open-source js-beautify library, the same formatter built into many code editors, and minifying uses Teasoft’s built-in HTML minifier. Your HTML is not sent to Teasoft or anyone else, so you can safely format private templates, client projects and code that contains internal URLs.
What happens to each part of your HTML:
| Part of your HTML | When you beautify | When you minify |
|---|---|---|
| Tags and nesting | Each block element goes on its own line, indented by depth | Whitespace between tags is removed |
| Text content | Kept as written, wrapped only if line wrapping is on | Runs of spaces and line breaks become a single space |
| CSS in <style> | Formatted with one rule and property per line | Extra spaces are removed to shrink the stylesheet |
| JavaScript in <script> | Indented and formatted | Trimmed, but the code itself is left unchanged |
| <pre> and <textarea> | Left exactly as written | Left exactly as written |
| Comments | Kept | Removed by default, except conditional comments |
| Attributes | Laid out using your Attributes setting | Extra spaces inside tags are removed |
Common reasons to format HTML
- Reading minified or single-line HTML copied from a live website or View Source.
- Cleaning up HTML exported from WordPress, page builders, email builders and WYSIWYG editors.
- Spotting nesting mistakes, such as a missing closing tag, once indentation shows the real structure.
- Making code reviews and Git diffs easier by giving the whole team the same indentation style.
- Preparing clean HTML snippets for documentation, tutorials, forum answers and blog posts.
- Minifying HTML templates and email code to cut file size before you publish.
What each control does:
| Control | What it does | When to use it |
|---|---|---|
| HTML input box | Holds the HTML you want to format | Paste code or drop a file here. Press Ctrl + Enter to beautify. |
| Upload, Paste, Sample and Clear | Opens a file, pastes from your clipboard, loads example code or empties the box | Upload accepts .html, .htm, .xhtml and .txt files. Use Sample to try the tool first. |
| Indentation | Sets each level to 2 spaces, 4 spaces or a Tab | Match the style used in your project or code editor. |
| End with a new line | Adds a final line break to the result | Keep it on for files you save in Git or a code editor. |
| Blank lines | Keeps up to 2 existing blank lines between blocks | Turn it off to remove every empty line. |
| Line wrapping | Wraps long lines at 80, 100 or 120 characters | Leave it Off unless your team has a line-length limit. |
| Attributes | Controls how attributes are laid out in each tag | Choose One per line for tags with many classes, data or ARIA attributes. |
| Indent <head> and <body> | Indents the head and body inside the html tag | Turn it off for a flatter layout of full pages. |
| Remove comments when minifying | Strips HTML comments from minified code | Turn it off to keep licence notes or developer comments. |
| Beautify HTML and Minify HTML | Runs the formatter or the minifier | Beautify to read and edit. Minify to publish. |
| Copy, Download and Use as input | Copies the result, saves it as formatted.html or moves it back to the input box | Use as input lets you run the same code again with different settings. |
Good to know
- Formatting doesn’t fix broken HTML. The tool reformats your code as written. It won’t add missing closing tags or correct invalid markup, but clean indentation makes those problems easier to spot.
- Your content stays the same. Beautifying changes indentation and line breaks only, not your tags, attributes or text.
- Pre-formatted text is protected. Content inside <pre> and <textarea> tags is never reformatted, so code samples and spacing stay intact.
- Minify doesn’t rewrite JavaScript. Scripts are trimmed but not compressed. Use a dedicated JavaScript minifier if you need smaller scripts.
- Check template code after formatting. HTML mixed with PHP, Liquid, Handlebars or JSX may not indent perfectly, so review those lines before you save.

How to Format HTML (3 Steps)
Add your HTML
Paste your code into the HTML input box, click Upload to open an .html file, or drop a file onto the box. Click Sample to try the tool with example code.
Choose your settings
Pick 2 spaces, 4 spaces or Tab, then set line wrapping, attribute layout and blank lines to match your project’s code style.
Beautify or minify, then copy
Click Beautify HTML (or press Ctrl + Enter) for clean, indented code, or Minify HTML for the smallest file. Then click Copy, or Download to save formatted.html.
Tip: most modern projects use 2 spaces for HTML, while many older codebases and PHP templates use 4 spaces or tabs. Use the same setting as your code editor so your diffs stay clean. If the page also has a large stylesheet, run it through the CSS Formatter too.
Beautify or Minify: Which Should I Use?
| Task | Use | Why |
|---|---|---|
| Read or debug HTML from a live site | Beautify | Indentation shows how every tag is nested. |
| Review code or compare versions in Git | Beautify, with the same settings each time | Consistent formatting keeps diffs small and clear. |
| Edit tags with long class lists | Beautify, Attributes set to One per line | Each attribute gets its own line, so changes are easy to see. |
| Publish a page, landing page or HTML email | Minify | Smaller files load faster and use less bandwidth. |
| Share a snippet in docs or a tutorial | Beautify, wrapping at 80 characters | Short lines are easier to read on any screen. |
| Keep licence notes or developer comments | Minify, with Remove comments off | Whitespace is removed but your comments stay. |
Getting better results when you format HTML
- Match your project’s style. Use the same indentation as your code editor or .editorconfig file.
- Beautify before you debug. Clean indentation makes missing closing tags and misplaced elements easy to spot.
- Compare before you replace. Check the result against your original before you paste it back into your project.
- Minify only the final version. Keep a readable copy for editing and minify the copy you publish.
- Review template tags. If your HTML contains PHP, Liquid or Handlebars, check those lines after formatting.
After you format your HTML
- Check the result. Open the page in your browser and make sure it looks the same as before.
- Tidy the styles. Format your stylesheet with the CSS Formatter.
- Clean up scripts. Make JavaScript readable with the JavaScript Formatter.
- Check your data. Format API responses and config files with the JSON Formatter.
Frequently Asked Questions
How do I format HTML online?
Paste your HTML or upload a file, choose an indentation, then click Beautify HTML. Copy or download the clean code from the Result box.
Is Teasoft’s HTML Formatter free?
Yes. It is completely free, with no sign-up and no account needed.
Is my HTML code uploaded to a server?
No. Your code is formatted inside your browser on your own device and is never sent to Teasoft or anyone else.
What is the difference between beautify and minify?
Beautify adds indentation and line breaks so HTML is easy to read and edit. Minify removes extra spaces, line breaks and comments so the file is as small as possible.
Does formatting change how my page looks?
Beautifying changes only indentation and line breaks, not your tags, attributes or text. After minifying, check any layout that depends on spaces between inline elements.
Can it fix broken or invalid HTML?
No. The formatter tidies your code as written. It won’t add missing closing tags or fix invalid markup, but clear indentation makes those errors much easier to find.
Does it format CSS and JavaScript inside my HTML?
Yes. When you beautify, code inside <style> and <script> tags is formatted too. When you minify, CSS is compressed and scripts are trimmed but not rewritten.
Which indentation should I use?
2 spaces is the most common choice for HTML. Use 4 spaces or tabs if your project or team already does.
How do I put each attribute on its own line?
Open Attributes and choose One per line (force). Choose One per line, aligned to line up attributes under the first one.
Will it change text inside pre and textarea tags?
No. Content inside <pre> and <textarea> tags is kept exactly as written when you beautify or minify.
Can I keep comments when minifying?
Yes. Turn off Remove comments when minifying. Conditional comments for old versions of Internet Explorer are always kept.
