Why export Mermaid diagrams as WebP?
WebP is useful when Mermaid diagrams are embedded in web pages where performance matters. It can reduce file weight compared with PNG while keeping labels readable when exported at 2x or 4x.
Documentation sites
Export WebP diagrams for static docs, help centers, and knowledge bases where readers may load many images.
Product pages
Use WebP for diagram cards, feature explainers, and visual documentation embedded in marketing pages.
WebP export checklist
Smaller than PNG
WebP often produces lighter web images while preserving enough diagram clarity at 2x or 4x.
Browser-focused
Use WebP when the destination is a modern website. Use PNG when you need maximum compatibility.
Transparency support
WebP can preserve transparency in modern browsers, but PNG remains the safer choice for slide and document workflows.
FAQ
Questions about this Mermaid export workflow
Is WebP smaller than PNG for Mermaid diagrams?+
Often yes, especially for web publishing. The exact file size depends on diagram complexity, background, and browser encoder behavior.
Can WebP preserve transparent backgrounds?+
Modern WebP can preserve transparency. For maximum slide and document compatibility, PNG is still the safer transparent format.
Should I use WebP in GitHub README files?+
PNG is usually safer for README compatibility. WebP is better for your own blog, docs site, or product page where you control browser support assumptions.
Does WebP export run locally?+
Yes. The Mermaid render and WebP raster export run in your browser for the core workflow.
