Copy as Markdown by cllama

Turn anything you can select in your browser into clean Markdown - no
flipping to a viewer, no pasting into a converter website, no cleaning up
afterwards.

Right-click a selection, choose Copy as Markdown, and the Markdown is on
your clipboard. Choose Export as PDF instead and the same selection opens
as a tidy, print-ready document.


Most of them mangle anything that is not a paragraph. Copy as Markdown is
built on Turndown, the same
converter used by some of the largest note-taking tools, with the GitHub
Flavored Markdown plugin enabled - so the messy parts come out right.

• Code blocks keep their language. Fences are read from language-,
  lang-, highlight-source- and brush: class names, plus
  data-language and data-lang attributes. If the code itself contains
  backticks, the surrounding fence grows automatically so the block is never
  broken.
• Everything GitHub understands. Tables become pipe tables, task lists
  become - [x] items, and strikethrough uses the double-tilde form that
  every renderer accepts.
• Structure survives. Nested and ordered lists keep their numbering and
  indentation, headings use # style, and block quotes stay block quotes.
• Links and images stay useful. Relative URLs are resolved against the
  page you copied from, so they still work after you paste the Markdown into
  a note, a ticket or a README.
• Inline code is inline code. A <code> element inside a paragraph no
  longer gets double-wrapped the way naive converters do it.
• Scripts and styles are dropped. You get the text, not the page's
  plumbing.

Pick Export as PDF and the selection is converted to Markdown, rendered
in a clean A4 layout, and handed to your browser's print dialog. Choose
"Save as PDF" as the destination and you get a real vector PDF with
selectable, searchable text - not a screenshot of your screen.

• Page setup is A4 with sensible margins, and headings, tables, quotes and
  code blocks are styled for paper.
• Long code lines wrap instead of being cut off at the edge of the page.
• Images and web fonts are waited for before printing, so nothing comes out
  as a blank placeholder.

• No accounts, no sign-in, nothing to configure.
• No network requests at all. The extension never contacts any server;
  every library it uses is bundled inside it.
• No analytics, no tracking, no telemetry.
• No page content is ever read outside of the moment you invoke it. The
  content script only looks at your current selection when you click a
  context menu entry, and it does nothing at any other time.
• Nothing is written to disk. The one piece of temporary data the
  extension needs - the Markdown it hands to its own print page - is deleted
  as soon as that page has rendered it.

The same code ships as a Manifest V3 build for Chrome, Edge and other
Chromium browsers, and as a Manifest V2 build for Firefox. It also handles
the common annoyance of right-clicking in a tab that was already open when
the extension was installed: the extension injects its own content script
on demand and just works.
