Free HTML Viewer Online

The built-in HTML viewer online lets you preview exactly how your code renders in a browser — no need to save a file and open it locally. Paste your HTML or upload a file, hit Run/View, and see the output instantly. The viewer also highlights syntax issues as you work, making it useful for catching broken tags, missing attributes, or structural problems before they hit production. It's particularly handy for debugging email templates, landing page snippets, or any HTML you've received from a third party.

HTML Formatter — Clean & Indent Your Code Online

A messy codebase slows everyone down. The HTML formatter takes unstructured, minified, or machine-generated markup and turns it into clean, properly indented code you can actually read and maintain. Choose your indentation level — 2, 4, or custom spaces — and the formatter applies it consistently throughout your file.

It works equally well as an HTML text formatter for small snippets and as a full-file formatter for larger codebases. Upload an HTML file directly or paste code into the editor, format it in one click, and download the result. No character limits, no watermarks.

HTML Prettifier — Pretty Print HTML Online

Pretty printing HTML means adding consistent whitespace, line breaks, and indentation to compressed or poorly formatted code so it reads like structured prose rather than a wall of tags. The HTML prettifier here does exactly that — it parses your markup and outputs properly nested, human-readable HTML with zero manual effort.

Whether you want to pretty print HTML for code review, documentation, or simply to understand what a minified file is doing, paste it in and click format. The output mirrors what you'd get from running a local linter, without any setup.

Compress & Minify HTML Online

The minifier strips line breaks, extra whitespace, and redundant characters from your HTML — reducing file size without touching the structure or functionality of the code. Smaller HTML means faster page loads, which matters for both user experience and search rankings.

Paste your code or upload a file, click Minify, and download the compressed output. Works for both simple pages and complex template files.

FAQs

Use the indentation controls in the formatter — select your preferred spacing (2 spaces, 4 spaces, etc.) from the dropdown, paste your HTML, and click format. The tool applies your chosen indentation level consistently across every nested element in the file. This is particularly useful when working with minified HTML or code copied from a source that used different spacing conventions.

Yes — the tool works as a free HTML text formatter for any HTML content: web pages, email templates, snippets, or full files. There's no account required, no usage limits on paste-and-format operations, and no watermark on downloaded output.

Yes. HTML email templates are often written in a single line or delivered in a minified state, making them difficult to read or debug. Paste the email HTML into the editor and format it — the viewer will also render the output so you can check how it looks visually before making edits.

To view an HTML code preview, simply copy and paste your HTML code into the Input Text Editor to highlight syntax and detect any issues. Alternatively, you can upload an HTML file directly using the Upload File button. Once your HTML data is available in the editor, click the Run / View button to instantly preview the rendered output in the Output Editor. This tool is perfect for testing, debugging, and analyzing HTML code, ensuring it's error-free and ready for use.

Beautifying (or formatting) HTML adds whitespace, indentation, and line breaks to make the code readable for humans. Minifying does the opposite — it removes all unnecessary whitespace to reduce file size for faster page loads. Both options are available in this tool. Use beautify during development and debugging; use minify before deploying to production.
