Markdown Previewer

Markdown Previewer is a lightweight browser extension that allows users to write Markdown text and instantly see a formatted preview in a clean, modern popup. The extension provides a split-view interface where Markdown is typed on one side and safely rendered as HTML on the other. It supports common Markdown elements such as headings, lists, bold and italic text, code blocks, links, blockquotes, and horizontal rules. All rendering is done locally inside the browser without loading external libraries or contacting any servers. Markdown Previewer is designed for simplicity and focus. It does not inject content into websites, modify web pages, or access browsing activity. User input is processed only within the extension, and optional draft saving is stored locally on the user’s device. This extension is ideal for developers, writers, students, and content creators who want a quick way to preview Markdown formatting without leaving the browser or opening additional tools.
