PDFin, from Visual Integrity, is an AutoCAD plug-in that turns vector PDF files into editable CAD drawings. Rather than redrawing artwork by hand, you bring the PDF in and get an accurate drawing that can be modified in Autodesk AutoCAD and other Autodesk solutions. It's aimed at converting CAD drawings, floor plans, network diagrams, and organization charts.
From any computer-generated PDF, PDFin extracts editable CAD entities, layers, objects, and text. Images that come from scanned PDF files are handled differently: they're placed on a non-editable tracing layer, since PDFin is not designed to vectorize scanned drawings. That makes it a fit for vector PDF source material rather than scanned drawings.
The plug-in is built specifically for AutoCAD 2012 and higher and other compatible Autodesk programs that support the extension API, and it runs on Microsoft Windows. This release adds 2025 support. Users on AutoCAD 2011 and earlier can find an alternative version from the developer. You can try it free or send a file for the team to convert for you.
