Frequently Asked Questions

How do I export a Mermaid diagram as PNG?

Open your Mermaid code in DiaShot, click the PNG export button, and download a high-resolution image instantly. Free users get 1x resolution; Plus and Pro plans unlock 2x and 3x ultra-high-res exports. No installation required.

Is there a free Mermaid diagram editor?

Yes, DiaShot offers a completely free Mermaid.js editor with live preview, AI generation, and PNG export. You get 3 exports per day on the free plan. Upgrade to Plus ($9/mo) for unlimited exports, SVG, PDF, and PPTX.

Yes. DiaShot supports single-slide PPTX export on Plus plans and bulk multi-slide PPTX export on Pro plans. Perfect for dropping diagrams directly into presentations without screenshots.

What is the best Mermaid diagram editor in 2026?

DiaShot is rated the best Mermaid diagram editor for developers and product managers in 2026. It combines AI generation, premium themes, high-res export (PNG/JPG/SVG/PDF/PPTX), cloud sync, and a brand kit for professional diagrams.

How do I add my company logo to Mermaid diagrams?

The Best Way to Export Mermaid Diagrams as High-Resolution Images

Mermaid.js is the standard for text-based diagramming in software documentation, but exporting those diagrams has always been a pain. The official Mermaid Live Editor produces blurry PNGs, broken SVGs, and offers no batch export. Developers, product managers, and technical writers waste hours taking screenshots or fighting the CLI.

DiaShot fixes this. It is a browser-based Mermaid diagram editor designed for one purpose: turn your Mermaid code into beautiful, presentation-ready images in seconds. No install. No account required to start. Just paste your code and export.

Export Mermaid to PNG, JPG, SVG, PDF, and PPTX

Unlike the Live Editor, DiaShot exports exactly what you see in the preview. Choose PNG for blog posts, JPG for lightweight sharing, SVG for infinite scalability in documentation, PDF for print-ready technical papers, and PPTX for PowerPoint decks. Free users get daily PNG exports; Plus and Pro plans unlock all formats with 2x and 3x resolution scaling.

AI Diagram Generation with Gemini 1.5 Flash

Stuck on syntax? Describe your architecture in plain English and DiaShot's AI assistant writes the Mermaid code for you. "Draw a payment flow with Stripe webhook retry logic" becomes a valid sequence diagram in under 5 seconds.

Brand Kit for Professional Diagrams

Consultants and agencies need consistency. DiaShot Pro includes a Brand Kit that applies your company's primary color, secondary color, text color, border color, font family, and logo watermark to every export. Your diagrams look like they came from an in-house design team.

Bulk Export for Documentation Projects

Writing a 50-page technical spec? Export all your diagrams as a single ZIP or multi-slide PowerPoint in one click. No more repeating the same export workflow forty times.
