Choose the Right Source Image
When the source already shows clear nodes, arrows, labels, and grouping, the image to diagram converter has enough visual structure to work from. Use a screenshot, export, or photo only when the diagram is readable enough to justify rebuilding it instead of tracing it by hand.
A single, focused diagram with strong contrast and minimal clutter gives the image to diagram converter a better source than a crowded screen capture. Crop out menus, empty margins, and unrelated notes so the model can concentrate on the visible relationships.
