HTML Beautifier: Format and Clean HTML Code Online
HTML Beautifier uses Prettier, the same formatting engine used by VS Code, to turn pasted HTML into consistently structured, easier-to-read markup. Choose the indentation and print width before formatting, then copy the result for your editor, review, or commit. The tool runs entirely in your browser, so your HTML stays on your device while you work.
HTML Beautifier is an online HTML beautifier that formats markup with Prettier, the same engine VS Code uses. Paste or drop in HTML to get output that is more consistently laid out and easier to read. It is useful when the original markup is difficult to review, whether it was generated by a tool or written by someone else.
Before formatting, choose the indentation and print width. These options affect the layout of the formatted HTML. The tool applies Prettier to the input, helping make the structure clearer and making whitespace differences less distracting when you review changes. If the input does not parse cleanly, the tool can help identify the line where the issue occurs.
HTML uses tags and attributes to describe the structure and content of a document. Formatting does not convert HTML into another format; it presents the markup in a more readable layout. Developers often format HTML before committing changes, inspecting unfamiliar documents, or sharing a snippet in a bug report or code review.
The HTML Beautifier runs entirely in your browser. Your input is processed on your own device and is not uploaded, stored, or sent to a server. Once the page has loaded, the tool works offline, so you can format HTML without an internet connection.
This tool can help developers and DevOps engineers who want to inspect, review, or share HTML more easily. It is also useful for anyone who needs consistently formatted markup without manually adjusting its indentation.
Step 1: Paste or drop your HTML into the tool. It accepts HTML input and processes your content in the browser.
Step 2: Choose the indentation and print width you want. These options control how the formatted markup is laid out.
Step 3: Format the HTML with Prettier. Review the result for clearer, more consistently structured markup.
Step 4: Copy the formatted output into your editor, code review, or other workflow.
Use case: Make an unreadable, machine-generated HTML file easier to review before you commit it.
Use case: Check an HTML document you did not write against the formatting expectations for your project.
Use case: Produce consistently indented output so a diff highlights meaningful changes instead of whitespace noise.
Use case: Format a snippet before adding it to a bug report or code review, making it easier for others to read.
Use case: Check whether your HTML parses cleanly and locate the line where malformed input causes a problem.
Use case: Tidy a pasted HTML example before sharing it with teammates, so its structure is easier to inspect.
Use case: Apply a consistent print width to HTML before reviewing a document with others.
