DeMarkup

Convert any webpage to clean, well-structured Markdown and copy it to your clipboard.

DeMarkup turns any webpage into clean, well-structured Markdown in one click. It strips the navigation, ads, and clutter, keeps the content that matters, and puts the result on your clipboard or saves it as a .md file. FEATURES • One-click conversion — click the icon or press Ctrl+Shift+M (Cmd+Shift+M on Mac) • Smart content extraction — pulls the main article, drops the surrounding noise • Full page mode — convert the entire page instead, when you want everything • Selection support — right-click any highlighted text to convert just that • Download as .md — save files named after the page • Word, character, and token counts — useful for LLM context budgeting • Copy for LLM mode — prepends the page title and URL as context, strips images • YAML front matter — optional metadata header • Configurable — choose bullet style, heading style, and link style • Debug logging — built-in log capture with export, for filing bug reports TYPICAL USES • Save an article as Markdown for your notes app • Pull clean reference text into an LLM prompt without the page furniture • Archive documentation in a format that stays readable and diffable • Grab a quote or section without hand-cleaning the formatting PRIVACY DeMarkup makes no network requests. There are no analytics, no tracking, and no external API calls — every conversion happens locally in your browser, and your page content never leaves your machine. The Markdown conversion library is bundled inside the extension rather than loaded from a CDN, so no third party observes your usage.
