Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To format HTML, paste your markup into the input and the tool beautifies it in your browser, applying consistent indentation and line breaks so the structure is easy to scan. Review the formatted output, then copy it to the clipboard or download it as a file.
Because the formatter runs client-side, the HTML you paste is never sent to a server. That keeps proprietary templates and CMS snippets private and lets you format markup instantly, even offline, with no account required.
A lot of HTML work is not heavy development. It is cleaning up copied markup from a CMS, an email template, an embed snippet, or a page you are auditing for SEO. Minified or inconsistently indented HTML is hard to read, and a quick beautify makes it reviewable.
This formatter is intentionally a lightweight utility rather than a full code editor. It focuses on making pasted HTML readable fast, which is exactly what you want when the goal is to inspect structure, spot a missing tag, or tidy a snippet before pasting it somewhere else.
Short answers for the questions people usually have before trying a utility like this.
