What output formats can I download?

PNG (raster) for thumbnails and embeds, and SVG (vector) for sharper rendering at any size.

Which renderer is used?

GitHub-style CSS is applied to the rendered Markdown before snapshotting, so the image looks like a github.com README.

Can I control the width and theme?

Yes. Set the viewport width and pick light or dark theme to match where the image will be embedded.

Is the Markdown uploaded?

No. Rendering and image capture run entirely in your browser.

How to export Markdown as an image

GitHub-styled preview rendered to PNG via html2canvas, or to SVG with inline HTML.

01
Paste Markdown
GFM is supported — headings, code, tables, lists, blockquotes.
Parsing runs through marked with GFM extensions enabled — tables, task lists, strikethrough, and fenced code blocks all match GitHub’s rendering.

02
Set width
300–1600px. Determines wrap and final image dimensions.
Soft-break behaviour is configurable: by default a single newline becomes a space (CommonMark), toggle on for chat-style <br> insertion.

03
Pick format
PNG (2× retina raster) or SVG (scalable vector).
The preview is scoped under a .mde class so its CSS doesn’t bleed into the rest of the page. Output HTML is whitespace-controlled for clean diffs.

Download
html2canvas snapshots the DOM, your browser downloads the file.
Export covers both raw Markdown and rendered HTML; downloads stream as text/markdown or text/html via Blob + object URL.

Pro tips

Author Markdown that renders everywhere

GFM is the safe default

GitHub-Flavored Markdown is the de-facto baseline (tables, task lists, strikethrough). CommonMark is stricter but ubiquitous as a fallback.

Soft-break behaviour varies

A single newline is a space in CommonMark, a <br> in GFM. Toggle soft breaks when source matters.

Escape inside code fences

Backticks inside fenced blocks need a longer fence — three becomes four. Use ~~~ if your content has many backticks.

Anchors are slugified

GitHub lowercases, strips punctuation, and joins with hyphens. Duplicate headings get -1, -2 suffixes.

Tables need a header row

The dash row sets alignment (:---, :-:, ---:). Use Table Aligner for diff-friendly columns.

Front matter is YAML

Triple-dash blocks at the top of files are parsed by static-site generators. Use the Front-Matter Validator to catch syntax errors.

Use Cases

When to export to image

Embeds, social posts, slides.

Twitter / X embeds

Share code snippets where MD isn't rendered. Render path uses marked with GFM extensions enabled (tables, task lists, strikethrough, autolinks), so what you preview matches what GitHub publishes bit-for-bit. Soft-break behaviour is configurable for chat-style vs prose Markdown.

GFM-compliant

Discord

Long code blocks render better as image. Pairs cleanly with the Markdown Cheatsheet for syntax you can't quite remember — callout blocks, footnotes, definition lists. Output stays diff-friendly so style-only changes don't drown out real edits in PRs.

GitHub-perfect

Slide decks

Drop into Keynote/PowerPoint without restyling. Cross-platform safe: anchors, code fences, and tables behave identically on GitHub, GitLab, Bitbucket, and Gitea. Heading-anchor slugs follow GitHub's lowercase-and-hyphenate rules so deep links survive a docs migration.

diff-friendly

Email

Markdown-rendered HTML in mail clients is unpredictable. No server roundtrip — perfect for proprietary content you can't paste into a public tool. The full marked + GFM bundle ships with the page, so it works offline once loaded.

render-stable

Blog assets

Pre-rendered images for CMS that lack MD. Front matter (YAML / TOML / JSON) passes through unchanged so static-site pipelines (Jekyll, Hugo, Astro, Eleventy) read it correctly. Pair with the Front-Matter Validator to catch syntax errors before deploy.

cross-platform

Print

SVG export prints crisp at any DPI. Output is reproducible: identical input always produces identical Markdown, so doc-generation scripts can rely on it for snapshot tests and embedded into release workflows.

FAQ

Frequently asked questions

PNG vs SVG?

PNG is a 2× rasterized snapshot — great for social sites. SVG embeds the HTML in a foreignObject — scales infinitely but needs SVG-capable viewers.

Why GitHub theme?

Familiar styling. Copy this tool and swap CSS for custom themes.

Code highlighting?

Not bundled — pipe through highlight.js first if you need it.

Max width?

1600px. Larger needs custom CSS to avoid wrap glitches.

Is anything sent to a server?

No — rendering and export happen locally in your browser.
