Three SDKs. One PDF Engine.

The PDF Lifecycle for Developers

Build exactly what you need at each stage: convert PDFs into editable vector data, inspect and manipulate internals, and generate polished PDF output—powered by the same battle-tested engine. Not sure where to start? Begin with the Conversion SDK for CAD/vector workflows, add Custom for object-level control, and use Creation to automate PDF output.

Download the PDF SDK

PDF Conversion SDK

Turn PDFs into Editable Vector & CAD

High-accuracy conversion to SVG, DWG/DXF, EMF/WMF, CGM, plus raster outputs—no printer drivers, built for batch and server use.

  • PDF/PS/EPS/AI → SVG, DWG/DXF, EMF/WMF,  images
  • Precise text, curves, layers, scale
  • Windows · macOS · Linux

PDF Object SDK

Understand & manipulate PDF internals

Object-level access to text, paths, images, layers, and metadata. Filter or modify content before import or export.

  • Selective extraction & redaction
  • Geometry queries & object edits
  • Supports PDF 2.0

PDF Creation SDK

Generate, merge & automate PDF output

Programmatically build PDFs, merge documents, stamp/watermark, and handle page-level operations with font embedding & Unicode.

  • Create & combine PDFs
  • Stamping, watermarking, page ops
  • .NET · Windows · macOS · Linux

PDF SDK Sample Workflows

Combine the Conversion, Object Control, and Creation SDKs to fit your pipeline.

Import  → Engineer → Output

Import and Edit PDF for CAD Applications

PDF → DWG/DXF for CAD

Convert supplier PDFs into clean, editable DWG/DXF with layers, scale, and precise curves.

  • Conversion SDK for PDF→DWG/DXF
  • Optional: Object Control SDK to strip art/annotations

PDF Process Automation

Merge, Stamp & Watermark at Scale

Automate page operations, stamping, and brand-safe output across thousands of documents.

  • Creation SDK for stamping/merge/page ops
  • Optional: Object Control SDK to mask/remove content

Generate Web Graphics

PDF → SVG for the Web

Publish crisp, zoom-safe diagrams and schematics directly as SVG with selectable text.

  • Conversion SDK for PDF→SVG
  • Optional: Creation SDK to assemble page sets

Compliance

Redaction & Sensitive Content Handling

Programmatically find/remove layers or objects, then regenerate shareable, compliant PDFs.

  • Object Control SDK to detect & remove
  • Creation SDK to rebuild final PDF

    Text Extraction

    Object-Level Extraction & Filtering

    Pull exactly what you need—text, paths, images, layers—before importing into your native model.

    • Object Control SDK to query/edit objects
    • Optional: Conversion SDK to finalize export

    Cloud Conversion

    Server & Cloud Batch Conversion

    Spin up headless services to convert, extract, and publish assets on demand.

    • Conversion SDK for batch ingest
    • Creation SDK to assemble deliverables
