When JPG is the right Mermaid format
JPG is not the highest-fidelity diagram format. It is the compatibility fallback: use it when the destination expects a normal photo-style image and rejects transparency, SVG, or modern web formats.
CMS uploads
Some CMS image fields reject SVG or WebP. JPG is a predictable fallback for article bodies and help centers.
Legacy workflows
JPG is useful for older presentation, ticketing, and document tools that only accept common raster files.
JPG export rules
No transparency
JPG cannot preserve alpha. The exporter uses a solid background; use PNG for transparent slides.
White background by default
JPG diagrams should look like clean document images, not cutouts. Start with Clean Docs or Editorial Card.
Use 2x or 4x
JPG compression can soften small labels. Higher scale keeps Mermaid text readable after resizing.
