PDF Intelligence API - Visual Integrity
by Visual Integrity
Convert, extract, and analyze PDF drawings; Vector objects returned as JSON, AI Summaries.
Visual Integrity PDF Intelligence API is a production-grade REST API that converts PDF, EPS, and PostScript files into editable CAD, vector, raster, and document formats, extracts structured vector data as JSON, and provides AI-powered document analysis. Built on 30 years of conversion technology trusted by Oracle, Delta Airlines, Amazon, BASF, and Siemens, it is the only Azure-native API that converts PDF files directly to DWG and DXF.
File Conversion
Convert to 16 output formats with 46 configurable options:
- CAD: DWG, DXF, HPGL
- Vector: SVG, EMF, WMF, CGM, EPS
- Raster: PNG, JPG, TIFF, BMP, GIF
- Document: PDF, PostScript, Text
Format-specific options include AutoCAD version targeting, DPI control, layer assignment modes, CMYK output, compression selection, text-combining strategies, and shape recognition, all controllable on a per-request basis via the API.
Object Extraction
The Object Extraction endpoint returns every vector object from a PDF page as structured JSON — polygons, polylines, text, and images with typed geometry, mm-precision coordinates, color values, and layer assignments. Purpose-built for engineering analysis, GIS data recovery, automated QA, and programmatic access to drawing content without manual conversion.
AI-Powered Document Analysis
An integrated AI analysis endpoint characterizes uploaded PDFs automatically — identifying document type (born-digital vector, scanned raster, hybrid), quantifying object composition, detecting layers, evaluating text editability, and recommending the optimal conversion strategy. Powered by Claude, it gives developers and end users an instant technical assessment before committing credits to conversion.
Developer Experience
- Interactive demo with file conversion, object extraction visualization, and API explorer — try all endpoints directly at the API URL
- OpenAPI 3.0 documentation with complete schema definitions
- Simple REST workflow: upload → poll → download, with secure time-limited download links
- API key authentication with per-key credit tracking
Pricing
Credit-based, pay-per-page pricing with no minimums, no setup fees, and no monthly commitments. Each page converted or extracted consumes credits from the subscription balance. Ideal for evaluation at low volume and scalable for enterprise workloads.
