HTML Formatter, Minifier and Preview
Format or minify HTML, inspect an isolated preview, extract links and convert to Markdown. Your documents are processed locally in the browser.
Format an HTML structure before reviewing it. Link extraction produces a list of anchor text and addresses. Markdown conversion is useful for written content such as headings, paragraphs and lists, subject to the elements that Markdown can represent.
