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.
How does the long image renderer ensure visual integrity for long articles?
The rendering engine uses segmented canvas measurement to calculate total height, producing a continuous high-resolution image without text clipping.
