PowerPoint to Mind Map
Each slide in a presentation has a title and bullet points — exactly the structure a mind map needs. SpawnGraph reads the .pptx file and turns slide titles into branches and bullet points into sub-nodes. Great for turning lecture slides into revision maps and long pitch decks into one-screen overviews.
How it works
- 1Save as .pptx. Most presentation tools export to .pptx by default. Google Slides and Keynote both have a "Download as PowerPoint" option.
- 2Drop it onto SpawnGraph. The browser File API reads the file locally — no upload, no server round-trip.
- 3Slide titles become branches. Each bullet point becomes a child node. The result is a fully editable mind map on the canvas.
Why convert PowerPoint slides to a mind map?
Slides are designed for presenting, not for studying. They reveal one idea at a time, which is the right shape for an audience but the wrong shape for revision or review. A mind map of the same slides collapses fifty slides into a one-screen overview where every title is a branch and you can drill into the bullets only when you need them. Most useful for: students working through lecture slides before an exam, analysts reading presentation decks shared by a colleague, anyone reviewing a long deck before a meeting, and product teams turning a pitch into a structured discussion outline.
What PowerPoint formats are supported?
SpawnGraph accepts .pptx (PowerPoint 2007 onwards), which is the format every modern tool can export to. Google Slides exports via File → Download → Microsoft PowerPoint. Keynote exports via File → Export To → PowerPoint. LibreOffice Impress saves natively as .pptx or .odp (use the broader File to Mind Map path for .odp). Older .ppt files convert cleanly inside PowerPoint or Keynote with a Save As → .pptx.
From lecture slides to revision map
The student workflow: download the lecturer's slides as .pptx (most learning management systems offer a direct download), drop the file onto SpawnGraph, get a mind map with every lecture topic as a branch. Collapse the sections you already know well. Focus on the branches that need revision. Rename nodes to use your own words rather than the lecturer's exact phrasing — your memory hooks into your own language better. Export the final map as a PNG for your phone wallpaper the day before the exam. See the students use case for more revision workflows.
Editing after conversion
The imported map is a starting point. Rename nodes to use your own phrasing (better for retention than the lecturer's exact words). Recolour by topic so related sections share a visual identity. Add your own child nodes for examples, connections the slides did not make, or questions you want to come back to. Share with your study group via a live link — the free tier includes real-time collaboration, see the collaborative mind map page for details.
In short: SpawnGraph converts .pptx PowerPoint files into editable mind maps in the browser. Slide titles become branches, bullet points become child nodes. No upload, no signup required.
