Local file processing
Supported documents are opened and processed by the Windows application. They do not need to be transferred to a cloud conversion service.
ViewCompanion for Windows
Keep sensitive PDF and CAD files off the cloud
View, print, annotate, measure, compare and convert technical drawings locally on your own computer. ViewCompanion gives engineering teams practical document tools without requiring confidential files to be uploaded to an online viewer.
Designed for confidential technical documents
Online viewers can be convenient, but uploading is not appropriate for every drawing. Local desktop processing helps you retain control of customer data, engineering revisions and internal documentation.
No account required
Install the software and work directly with files on your computer or company network without signing in to a hosted viewing platform.
No embedded PDF JavaScript
ViewCompanion does not execute JavaScript embedded in PDF documents, reducing an unnecessary source of active content during review.
