How to turn Markdown into an image (3 steps)
Full workflow: sharing AI chat output as an image
Example: Markdown → PNG image
A code snippet worth sharing in a chat thread.
# deploy.sh
```bash
./deploy --region emea --wait
```
Card layout preview — the export is a finished 2× PNG/JPG image rendered locally in this style.
deploy.sh
./deploy --region emea --waitWhat converts natively (and what doesn't)
| Feature | Result in the PNG image |
|---|---|
| Headings, lists, tables, code | Native — Rendered onto the card with matching styles |
| Image width | Native — 640, 800 or 1200 px |
| Light / dark card | Native — The preview shows exactly what downloads |
| Sharpness | Native — Rendered at 2× so text stays crisp in chat apps and on high-DPI screens |
| Long documents | Native — Auto-split at block boundaries into numbered pages, delivered as a ZIP, when one image would exceed safe canvas limits (engine v0.4.0) |
| Embedded data-URI images | Native — Local inline images are drawn into the card; relative/remote references render as labelled placeholders (never fetched — they would taint the canvas) |
| Remote images | Not supported — Never fetched — no third-party request is made on your behalf |
| JPG variant | Native — JPG pre-fills the card background colour (JPG has no transparency) |
Full element-by-element ground truth, with test dates: format support.
What this tool does not do
- No: SVG or WebP export — PNG and JPG only
- No: Custom fonts, or colours beyond the two themes
- No: Cropping or annotations
- No: Remote images — by design, never fetched
What people use Markdown to Image for
Frequently asked questions
PNG or JPG — which should I choose?
PNG is the default: lossless with optionally transparent surroundings, so text stays crisp at any size. JPG is smaller and ideal for photos-heavy content — white is filled in for the background because JPG has no transparency.
How are images inside the Markdown handled?
Inline data-URI images are embedded in the card; remote images are never fetched — the same privacy rule as every DocsFast tool.
Is the text really crisp?
Yes. The card is rendered at 2× resolution, so on high-DPI screens and in chat apps the text stays sharp.
Can I change the size and look?
Choose a 640/800/1200 px width and a light or dark card style — the live preview shows exactly what you will download.
Which width should I use for chat?
800 px is the default and suits chat clients and social posts; 640 fits narrow threads and 1200 suits blog embeds. Every size renders at 2× for crisp text.
Does the PNG have a transparent background?
The card uses its theme's background colour (light or dark) and PNG keeps it exactly; choose JPG instead and the background is filled white, because JPG has no transparency.
What is the small footer line?
Every card carries a subtle “Rendered with DocsFast — local, private Markdown → image” line as part of the design, so people who like the output know where it came from.
What happens with very long documents?
Long Markdown is split at block boundaries into numbered pages — page 2 begins exactly where page 1 ended, never mid-sentence — and the pages arrive as a ZIP (engine v0.4.0). This exists because browsers cap how large a single canvas image can be; splitting keeps every page inside that limit, so nothing comes out blank or truncated.
Can I share a code snippet as an image without a screenshot tool?
Yes — paste the fenced code block, pick a width and theme, and download a 2× PNG rendered in your browser. Text stays crisp in chat apps and on high-DPI screens, and nothing was uploaded to do it.
Where do Markdown-to-image cards get used?
Mostly chat and social: code snippets in Slack or Discord, tables and notes in community posts, and documentation screenshots where a live document would be overkill. The card footer links back here.
