Frequently Asked Questions
It restructures your markup's whitespace and indentation — lining up nested tags, adding line breaks, and applying consistent spacing — so the underlying HTML is easier for a developer to read, without changing how the page looks or behaves in a browser.
Yes — paste in a compressed, single-line HTML string and this HTML formatter expands it into properly indented, multi-line code, which is useful when you're inspecting a page's source, debugging a template, or reviewing a bundler's compiled output.
No. Formatting only changes indentation and line breaks in the underlying code — the rendered page, its layout, and its styling stay exactly the same for anyone visiting the site.
Yes — switch to the Minify tab to strip out unnecessary whitespace and line breaks, which shrinks the file size for faster page loads in production.
No. All formatting and minifying happens locally in your browser, so the markup you paste — including any private or unreleased code from a client project — is never transmitted to or saved on our servers at any point during processing.
No practical limit — paste a small snippet or an entire page's markup, and the formatter processes it instantly, free, with no signup required, no matter how many times you need to reformat it during a session.
Yes. Before formatting, you can choose your preferred indentation size, such as 2-space or 4-space tabs, along with attribute spacing rules, so the output matches your team's coding standards. This lets you tailor the beautified structure to fit your project's existing style guide instead of a fixed format.
