Image to Mermaid Converter
Upload a flowchart screenshot, diagram image, or diagram image and convert the visible structure into editable Mermaid code you can review, refine, and use in documentation.
Converts visible flowchart structure into an editable Mermaid code draft.
Useful for Markdown, GitHub, Notion, README files, and technical documentation.
Review the result on canvas, then copy or export the latest Mermaid source when available.

From diagram image to editable Mermaid code
Upload a flowchart screenshot or diagram image. ImageToEditable rebuilds the structure and generates Mermaid code you can copy into docs, GitHub, or Markdown.

What to expect
Best for clear flowcharts and architecture diagrams. Review dense labels and branch directions before publishing.
Generate Mermaid codeHow conversion works
Start with the source file, let AI rebuild the visible structure, then review the editable result on canvas.
2
AI rebuilds the diagram
ImageToEditable detects visible steps, decisions, labels, arrows, and connector direction.
3
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
ImageToEditable 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 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.
Image conversion workflows
Built for diagrams that need another edit
Choose the converter that matches your source image or the editable output you need.
GitHub docs
Convert diagram screenshots into Mermaid source for README files and engineering docs.
Markdown documentation
Recreate flowcharts as text-based diagrams for docs sites, wikis, and knowledge bases.
Notion notes
Recover diagram structure from screenshots before adding the process to team notes.
Architecture notes
Turn simple architecture diagrams into editable Mermaid code drafts for technical planning.
Process diagrams
Convert workflow screenshots into Mermaid flowcharts that are easier to edit and maintain.
Before you upload
What to review after conversion
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 diagram image, but you need editable Mermaid code for documentation.
ImageToEditable 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.
Results and quality
Supported outputs and best results
Upload a clear PNG, JPG, JPEG, or SVG diagram image. For a diagram inside a document, export or capture the relevant page as an image first.

Best results checklist
- Use a clear image 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.
- 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
Continue from the converted diagram without rebuilding the file.
Open editable canvas
Continue refining the rebuilt diagram with manual edits.
Export target files
Export the finished diagram as a Draw.io, Mermaid, Excalidraw, PNG, or SVG file when available.
Review the draft
Check labels, shapes, arrows, and connectors before you share the result.
