Choose the right Mermaid export format

Mermaid2Img exports the same diagram in several formats so you can match the file to the job before downloading.

PNG
READMEs, tickets, docs, and chat

Use PNG when you need a crisp bitmap that works almost everywhere.

JPG
Small files and quick sharing

Use JPG for lightweight previews when transparency is not important.

SVG
Vector docs, websites, and design handoff

Use SVG when you need scalable lines, selectable text, or later styling.

PDF
Print, proposals, and presentation decks

Use PDF when the diagram needs to travel as a document artifact.
