Review Mermaid code
Open the generated canvas, check the structure, and use the latest Mermaid source when available.
Editable result
What you can edit after conversion
ChatFlowchart rebuilds the visible diagram as editable diagram objects, so the output can be reviewed and refined instead of staying locked inside a flat image.
Labels
Review and edit the visible text labels after the diagram is rebuilt.
Shapes
Move, resize, add, or remove process boxes, decision nodes, and other diagram elements.
Connectors
Reconnect arrows, adjust flow direction, and fix unclear branches when needed.
Layout
Clean up spacing, alignment, grouping, and reading order on the editable canvas.
Style
Apply sketch or modern styling before exporting the final diagram.

Details
What to know before converting
Convert images and screenshots to Mermaid code
Image to Mermaid conversion is useful when a flowchart or process diagram only exists as a screenshot, export, or PDF page, but you need editable Mermaid code for documentation.
ChatFlowchart rebuilds the visible diagram structure into an editable draft so you can review the flow, refine the labels, and use the Mermaid source where available.
Create code-backed diagrams for docs workflows
A screenshot to Mermaid workflow helps developers, product teams, and technical writers turn static diagrams into code-backed diagrams for Markdown, GitHub, Notion, README files, and docs.
For best results, start with high-contrast flowcharts, decision trees, and process diagrams with readable labels. Dense screenshots, tiny text, or complex non-flowchart layouts may need manual cleanup.

Supported outputs and best results
Images, screenshots, whiteboard photos, and PDF uploads are supported. Text-based PDFs can be extracted directly, while scanned PDFs work best when the diagram, labels, and arrows are clearly visible.

Best results checklist
- Use clear images or PDF pages with readable labels.
- Crop the upload to one diagram or one process when the source contains multiple unrelated charts.
- Keep arrowheads, connector lines, and decision labels visible.
- Use high-contrast screenshots or straight-on whiteboard photos.
- Review labels, arrows, and branch directions before exporting the final diagram.
- Use clear flowchart screenshots with readable labels when you need Mermaid code for documentation.
Limitations and cleanup
- Dense diagrams may need manual cleanup after the first AI rebuild.
- Blurred, cropped, or low-contrast text can reduce label accuracy.
- Scanned PDFs and image-style PDFs work best when the target page is clear.
- The result is a rebuilt editable diagram, not a recovery of hidden source metadata.
- Connector direction, branch labels, and complex layouts may need review before sharing.
- Generated Mermaid code may need syntax, label, or layout cleanup for dense, blurry, or non-flowchart diagrams.
After conversion
Open editable canvas
Continue refining the rebuilt diagram with manual edits or AI chat.
Export target files
Export the finished diagram as PNG, SVG, PDF, Draw.io, Mermaid, or a shareable link when available.
Fix with AI chat
Ask ChatFlowchart to rename labels, adjust steps, clean up layout, or correct arrows.
Report conversion quality
Mark whether the result looks good or needs cleanup so weak inputs are easier to diagnose.
Conversion feedback
After reviewing the rebuilt diagram, mark what worked or what needs cleanup so future conversions can improve.
FAQ
Questions before you upload
Can I convert an image directly into Mermaid code?
Yes. Upload a clear flowchart screenshot or diagram image and ChatFlowchart can generate an editable Mermaid code draft from the visible structure.
Can I copy Mermaid code?
Use the Mermaid result after generation. Copy availability depends on whether the current generated canvas exposes the latest Mermaid source.
Can I download a .mmd file?
Yes. Use the Mermaid export option from the generated canvas when the latest Mermaid source is available.
What diagrams work best?
Clear flowcharts, decision trees, workflow screenshots, and simple process diagrams work best. Dense screenshots may need cleanup.
Can I use a PDF?
Yes. Use a clear PDF page or screenshot. Text-based PDFs and image-style PDFs may require review before the Mermaid result is ready to publish.
Will the Mermaid code be final?
Review and refine the generated Mermaid code before publishing, especially connector direction, decision labels, and branch wording.
