Architecture, Engineering and Construction

Easily add accurate, reliable and fast document processing into your AEC software with a PDF SDK proven to handle the large and complex drawings used in today’s construction workflows.

Proven Stability and Market Reputation

Accurate, Reliable & Fast

Have confidence that complex blueprints will present quickly and flawlessly, even at high zoom -- using a PDF rendering engine optimized for over 20 years.

Many File Formats, Any Platform

Standardize on a universal document viewer. Ensure identical viewing and collaboration on PDF, CAD, BIM, MS Office and image format files across all major platforms.

Customizable UX/UI

Improve adoption by simplifying the open source UI to appeal to non-tech savvy users. And customize PDF markup annotations to integrate with existing software, and trigger workflows.


Have onsite workers view, markup, fill forms, and edit documents offline on web, mobile, or desktop -- with no servers or other external dependencies required.

Built-in AEC Features

CAD, PDF and Office Viewing (and 30+ file formats)

Convert from popular MS Office, and CAD and BIM formats, including Autodesk AutoCAD® DWG™ and DXF™, and Bentley MicroSation® DGN™.

Real-time Collaboration

Have markups from many users appear on the same document in real time while preserving an original version of the drawing. Manage annotations in a separate XFDF layer. Add roles, permissions or an audit trail.

All Markup Annotations

Drop in or remove all types of existing PDF markups, including stamp, watermark, call-out comments, free text, signature and shape tools, and more. Have users embed photos straight from a camera or mobile device. Learn More

Workflow Automation

Standardize and streamline review and approval, inspections, issue resolution, takeoff, and more. Separate out PDF markups and measurements for easy integration into any software system or app.

Custom Annotation Appearances

Change how your markups look and build libraries of industry-standard stamps that display consistently across desktop, mobile and web-based apps.

Snap to Point

Get out-of-box annotations that snap to control points in a drawing and enable accurate measurement of lines, area, arc and perimeter.

Interactive Forms

Accelerate onsite inspections by embedding punch- and check-list workflows directly into documents via features to generate interactive and fillable PDF forms. Learn More

Compare PDF/CAD/Image Files

Make it easy to spot slight visual differences at a glance with version comparison features. Compare documents side by side or in version overlays with highlighted changes.

Offline Mode

Have onsite workers view, edit, and annotate when offline or dealing with spotty internet. And reliably sync annotations between users in multiple places once a connection is established.

Support for Brava! Annotations

Keep working on drawings marked up in Brava!® on PDFTron’s native and web-based viewers. Convert Brava! annotations in XRL™ to XFDF -- the ISO-standard format for annotations interchange.

Add Even More Functionality

Speed time to market with the most complete PDF SDK on the market -- supporting all major platforms, 30+ file formats, and hundreds of other unique features. Learn More

PDFTron’s AEC Customer Success Stories

Testimonial quote
Our primary requirement was, here is a big chunk of demanding PDF files. Can you open them? When we pushed most of these 190 PDFs through PDFTron, we couldn’t find one that didn’t open. And from what I could tell, PDFTron handled the memory issue the best... I absolutely feel we’re in a better position to handle all our present and future PDF requirements.
