What is the Markdown Viewer?
The Markdown Viewer is a free online tool that renders any Markdown (.md) file into clean, formatted text exactly the way it would appear on GitHub, GitLab or a documentation site. Open a file or type Markdown directly and watch a live preview build as you write — complete with headings, lists, links, images, tables, task lists and syntax-styled code blocks. Everything runs in your browser, so your notes and documents stay completely private.
GitHub-Flavored Markdown Rendering
The viewer supports GitHub-Flavored Markdown (GFM), so the features you rely on every day just work: pipe tables, fenced code blocks, - [ ] task lists, strikethrough, blockquotes, ordered and unordered lists, inline HTML and automatic links. Whether you're previewing a README, release notes, a blog draft or technical documentation, the output matches what readers will eventually see.
Live Split Editor with Synced Scrolling
Split view places an editable Markdown editor beside the rendered preview, and the two panes scroll together so the part you're editing always stays in view. Type on the left and the formatted result updates instantly on the right — a fast, distraction-free way to draft documentation, fix formatting, or learn Markdown syntax by experimenting.
Automatic Table of Contents
Every heading in your document is collected into a clickable table of contents. Open the Contents panel to jump straight to any section — invaluable for long READMEs, manuals and articles. The outline is generated automatically and updates as you add or rename headings.
Responsive Widths, Fullscreen & Export
Preview your document at desktop, tablet or mobile widths to see how it reads on different screens, or go fullscreen to focus on the content. When you're done, copy the rendered HTML, copy the Markdown, download a polished standalone .html file, download the .md source, open the result in a new tab, or print it — all from a single toolbar.
Privacy First — Nothing Leaves Your Browser
Your Markdown is parsed and rendered locally on your own device. No file is ever uploaded to a server, logged or stored, which makes the viewer safe for confidential notes, internal documentation and unpublished drafts. When you close the tab, the content is gone for good.
