Is this online Markdown editor free?

Yes — PDFFlare's online Markdown editor is 100% free with no signup, no character limits, and no watermarks. Write as much as you want, as often as you want.

Does my document get uploaded to a server?

No. The editor runs entirely in your browser using JavaScript. Your Markdown is parsed, rendered, and auto-saved on your device — nothing is transmitted to a server.

Will my draft be saved if I close the browser tab?

Yes. The editor auto-saves your current document to your browser's localStorage every quarter-second. When you reopen the page, your last draft is restored automatically. Clearing browser data will erase the saved draft.

What Markdown features are supported?

All the common ones: headings (H1–H6), bold and italic, links, inline code, fenced code blocks, blockquotes, ordered and unordered lists, horizontal rules, and GitHub Flavored Markdown (GFM) tables with column alignment.

Are there keyboard shortcuts in the markdown editor?

Yes. Cmd/Ctrl + B wraps the current selection in bold, Cmd/Ctrl + I in italic, and Cmd/Ctrl + K turns it into a Markdown link. The toolbar also reflects every action, so you can mouse and keyboard interchangeably.

Can I export the rendered output as HTML or PDF?

Yes. Click Download .html to save a standalone styled HTML file, or click Copy HTML to grab the rendered markup. To export as PDF, paste the copied HTML into our HTML to PDF tool — same browser-only flow.

Can I import an existing .md file into the editor?

Yes. Click the “Load .md” button in the toolbar to open a Markdown file from your device. The contents replace the current editor view, and you can keep writing from there.

Does the markdown editor work on mobile?

Yes. On smaller screens, the editor switches to a tab layout — toggle between “Edit” and “Preview” with one tap. The toolbar wraps and remains fully clickable on touch.

Why use a Markdown editor instead of a regular word processor?

Markdown is plain text, version-control friendly, and renders consistently anywhere — GitHub, Notion, Substack, static-site generators, technical documentation. A Markdown editor with live preview gives you formatting confidence without locking you into a proprietary file format.

Is the Markdown editor accessible (keyboard-friendly, screen reader)?

The editor is built with a real , labelled toolbar buttons, and aria-live word/character counters. Screen readers announce both the toolbar actions and the running stats. All toolbar buttons are reachable via Tab and activatable with Enter or Space.

How to Use the Markdown Editor

Start typing Markdown

See the live preview
The rendered output appears in real time on the right. On mobile, toggle between the Edit and Preview tabs. Your work auto-saves to your browser as you type.
Export your document
Click Download .md to save your Markdown source, Download .html for a styled HTML file, or Copy HTML to paste into a blog post or CMS. Everything happens locally — your text never leaves your browser.

When Do You Need a Markdown Editor With Live Preview?

Writing README files and project docs: GitHub renders Markdown the moment you push. A live preview editor lets you see the README exactly how it'll look on the repo page — heading sizes, code blocks, badges, tables — before you commit.

Drafting blog posts for static sites: Hugo, Jekyll, Astro, Next.js MDX — all of them consume Markdown. Drafting in a live preview editor avoids the compile-refresh loop and shows formatting issues immediately.

Taking structured technical notes: Code snippets, tables, ordered steps, blockquotes — Markdown handles them all in plain text. A Markdown editor with live preview lets you see structure without committing to a proprietary format like Notion or Word.

Composing rich-text email or CMS content: Many CMSes (Ghost, Substack, WordPress block editor) accept pasted HTML. Write in Markdown, copy the rendered HTML, paste into the CMS — done in three clicks.
