LayerBack

LayerBack is a specialized tool that turns images of diagrams — think flowcharts, architecture diagrams, org charts, or pretty much any visual with boxes and arrows — into fully editable Visio and PowerPoint files. Instead of just wrapping your screenshot inside a file container, it actually rebuilds the whole diagram using native shapes, real connectors, and editable text. Upload a PNG, JPG, WebP, or PDF (up to 20 MB), and in about 30 seconds you get back a VSDX, PPTX, draw.io, or SVG file you can open and edit directly.

Here's how it works: you drop an image on the site (or paste from clipboard), and LayerBack analyzes it to detect each shape, label, arrow, and color. Then it reconstructs the diagram using the native object model of your chosen output format. That means every rectangle stays a rectangle, every diamond stays a diamond, and every connector stays attached to the right shapes — move one and the lines follow. You can even edit the result right in your browser before downloading. The tool also offers a REST API and an MCP server for AI agents, so you can batch convert images or build automated pipelines.

LayerBack is most useful for anyone who regularly needs to update diagrams that exist only as screenshots or scanned hand-drawings. System architects, product managers, and technical writers who rely on Visio or PowerPoint for documentation will save hours of manual redrawing. It's also handy for teams migrating legacy diagrams — just batch them through the API. The free tier gives you 20 credits (about 2 full conversions) to try it out, no credit card required.
