Markdown to Long Image
This mode uses an auto-height canvas and presets export to a split ZIP. Every part keeps the width, theme and typography of the full preview.
How to use it
- Paste a long Markdown document
- Set the canvas width and split height
- Export the image parts as a ZIP
Limitations
The tool splits between content blocks where possible. A single image or complex table that is taller than the chosen part height can still produce an oversized part.

## 5. Next step
Continue checking images, tables and themes, then add the findings to the release checklist.
