When SVG is better than PNG

SVG is ideal when the diagram needs to remain sharp at any size, fit into a static site pipeline, or pass through a vector-aware workflow. It is less universal than PNG, so keep a raster fallback for platforms that block SVG uploads.

Static documentation sites

Use SVG when docs are built with frameworks that safely serve vector assets and benefit from resolution-independent diagrams.

Developer handoff

SVG is inspectable text, which makes it useful for design reviews, asset pipelines, and versioned documentation.

Vector workflows

Save SVG when you need to resize diagrams without blur or pass them into tools that understand vector graphics.

SVG export checklist

Need universal sharing?

Use PNG when the diagram must work everywhere, including email, issue trackers, and office tools.

Need editable markup?

Save SVG when you want a text-based vector file that can be inspected or transformed downstream.

Browser warns on SVG?

SVG is a text-based format, so some browsers or platforms treat downloads cautiously. Use HTTPS or export PNG as a fallback.

FAQ

Questions about this Mermaid export workflow

Is SVG the best format for Mermaid diagrams?+

It is best for scalable vector workflows, but PNG is safer for broad sharing. Use SVG when the destination accepts vector files.

Can I save SVG without uploading my Mermaid code?+

Yes. The Mermaid render and SVG export run in your browser for the core workflow.

Why might a browser warn about SVG downloads?+

SVG is text/XML and can contain active content in some contexts. This tool renders with strict Mermaid settings, but some local or insecure environments still show cautious browser messaging.

Should I use SVG for GitHub README files?+

PNG is usually safer for README compatibility. Use SVG when your publishing workflow explicitly supports it and you want scalable vector output.
