FAQ

How long can the image be?

Browser canvas limits vary. For very long documents, carousel pages are more reliable and use less memory.

Can it render code blocks?

Yes. Common code languages are highlighted locally with Shiki.

Markdown to Long Image: Will the exported document look identical in every viewer?

Not always. PDF viewers, fonts, image decoders, and browser rendering can differ. Open the exported file in the software used by the recipient before distributing it.
