PowerPoint Theme

Import Theme Drag and drop file here or click to browse

Use presentation theme reads the deck color scheme in PowerPoint (API 1.10+). Or use a .thmx file or exported theme1.xml. Colors are read from the Office color scheme (not random values elsewhere in the file).

Export

PowerPoint insert, image download, or shareable link.

Insert into slide uses SVG when PowerPoint allows it, otherwise PNG. Select exactly one slide shape before inserting and the graphic replaces it, scaled to match that shape’s width while keeping the diagram’s proportions. If the connection stalls, a PNG is copied for ⌘V / Ctrl+V. Use Export image for SVG (default) or PNG with scale options.
