When HD PNG is the right choice

PNG is a compatibility format. It is best when the destination does not accept SVG or when predictable raster rendering matters more than vector editability.

  • Slide decks and screenshots
  • Issue trackers and upload fields
  • Email and chat handoff

Prepare the diagram before export

Beautify the Mermaid source first so the PNG captures a clean final layout rather than a cramped default render.

Use SVG when possible

If the destination supports SVG, use SVG for sharper scaling. Keep PNG as the fallback for destinations that need raster images.

Check plan limits

HD PNG, watermark behavior, and export limits can depend on the active plan. Confirm the current plan before a production export workflow.

Guide FAQ

Questions about this workflow

Is PNG better than SVG?

PNG is better for compatibility. SVG is better for crisp scaling and long-term reuse.

Can I export without a watermark?

Watermark behavior depends on the active plan, so check the pricing page for current export rules.

Why does my PNG look blurry?

The image may be too small for the destination. Use HD PNG or SVG when the target size is large.
