/ what the PDF SDK does
Built for engineering PDF, not just office documents.
High-fidelity rendering
Vector and raster PDF rendered in the browser with no client-side plugin.
Annotations & markups
Notes, stamps, freehand, shapes. Events stream back so you store them where your data already lives.
Measurement tools
Distance, area, calibration. Scale-aware on engineering PDFs.
Compare & overlay
Compare two PDF revisions visually. Spot every change without an extra tool.
Need CAD or BIM too? The same engine reads DWG, DXF and DGN and IFC 3D models — one integration, every format.
