Compare Architectural Drawings in PDF
Plans, sections, elevations and details — every revision change between two architectural PDFs detected and highlighted automatically. Built for architects who don't have time to manually compare 80 sheets.
Why architectural firms use PDFverifier
Architectural drawings are dense — a single floor plan can have hundreds of dimensions, annotations, and graphic elements. When a client requests changes or coordination produces revisions, identifying every modification before reissuing is critical. Miss one wall move and the structural engineer's calculations may be invalid; miss one dimension change and the contractor builds it wrong.
PDFverifier compares two architectural PDFs at pixel level and highlights every difference: moved walls, modified dimensions, added details, removed annotations, even changes in hatching or line weights.

From CAD to PDF — works with any source
It doesn't matter which CAD tool produced the PDF — Revit, AutoCAD, ArchiCAD, Vectorworks, SketchUp Layout — PDFverifier compares the rendered output, so source format is irrelevant. As long as you have two PDF files, you can compare them.
