Diagram Smith Pro

What Pro adds

• Editable .drawio export: save the diagram for diagrams.net (draw.io) with real shapes, labels, arrows and every page. Flowcharts, swimlanes, data flow, decision trees, block, network, ER, UML class, sequence, use case, state and activity diagrams, Gantt charts, timelines, org charts, mind maps, concept maps and tree diagrams stay editable. Charts (pie, line, gauge, Sankey, Venn), SWOT, RACI, Eisenhower, circular flow, PERT charts, fault trees, decision matrices and word clouds go into the file as one picture, and the Export menu says so.
• Vector PDF: lines and text stay sharp at any zoom, the text can be selected and searched, and every page goes into the file. Vector PDF supports Latin-script text for now; for other scripts, keep using the free PDF.
• Multi-page documents: add a second, third and more pages to one diagram, duplicate a page, and export all pages into one PDF (a sheet per page). Free users get the page on screen.
• Layers: put shapes on named layers, hide, lock and reorder them, and keep them as layers in the .drawio file.
• Brand theme: your own colour on every shape and line of every page, in one click.
• Diagram checks: one button lists branches out of a decision without a label (Yes / No), steps with no way out, shapes that connect to nothing, missing start or end, and shapes that cannot be reached, and outlines them in red before you share the chart.
• Fault tree analysis: the top-event probability, every minimal cut set, rare-event bounds, the importance of each event and a CSV of the analysis (drawing the tree is free).
• PERT critical path: the highlight on the chart, the names of every critical path, a network check and the chance of finishing by a date (the chart, earliest and latest times, slack and CSV are free).
• Word cloud outlines: a cloud inside a circle, heart, diamond or triangle.
• Larger imports: org charts from a CSV or Excel .xlsx file and above 20 people (up to 150), ER diagrams from SQL above 5 tables (up to 40) and flowcharts from code above 60 lines (up to 2,000).
• WBS to Gantt: a work breakdown structure opened as a Gantt chart.
• Visio to flowchart: a Visio drawing opened in the Flowchart Maker as editable shapes. Viewing and exporting pictures of it is free.

What stays free

• All the tools and all editing: every shape, template and setting, with no sign-up. Style, arrange, resize, connector bend points, local pictures, the Lucide icon library and the Classic, Print, Blueprint, Pastel and Bold themes.
• Exports: PNG, SVG and a PDF of the page on screen (the PDF is a picture of the diagram), copy to the clipboard, all without a watermark.
• Saves in your browser (up to 30 named copies per tool) and share links. Your diagrams are not uploaded, with or without Pro.
• Imported pages stay yours: if you open a file or link that has several pages, you can view, switch, rename, reorder and keep them.
