ViewCompanion Premium

Multiformat viewer and converter

ViewCompanion Premium is the most powerful member of the ViewCompanion family. ViewCompanion Premium can view, print and convert Adobe PDF, PDF/A, AutoCAD DWG, Autodesk DWF, PLT, CGM, TIFF, CALS, EDMICS and several other file formats.

ViewCompanion Premium supports conversion to a wide range of output formats, including PDF. Please see the complete list of supported output formats below.


Work directly with AutoCAD DWG files without requiring AutoCAD. Open, view, print, batch print, annotate, measure, compare, and convert DWG drawings using the same tools available for other supported technical drawing formats.


The built-in PDF-to-CAD tools allow you to convert PDF files into editable DXF, Gerber, CGM, and SVG formats, making it easy to reuse drawing data in CAD and engineering applications.


ViewCompanion Premium

Add markups, also known as comments or annotations, to your documents.

Viewcompanion includes both batch conversion and batch printing.
You can also monitor a folder for incoming files and automatically print or convert them using predefined settings.
This makes it easy to automate repetitive document-processing tasks and streamline high-volume workflows.


Use ViewCompanion to measure distances, dimensions, and areas directly in your documents and drawings. Measurement points can snap to drawing geometry for improved accuracy.

The measurement tools can also be calibrated, ensuring correct results even when a drawing is not scaled at 1:1. Measurement results can be exported to an Excel workbook (XLSX) or a CSV file for further analysis in any spreadsheet application.


Use ViewCompanion to compare different revisions of a document or drawing and clearly visualize the differences.
All supported file formats can be compared, including PDF and DWG. Multipage files can be compared page by page.
Learn more about file comparison in ViewCompanion.


Annotate documents and technical drawings with text, highlights, dimension lines, area measurements, stamps, arrows, barcodes, symbols, images, freehand markup, and more.
All annotations are stored in a separate markup file, so the original document remains unchanged. Markups can also be included when printing or converting the document.

ViewCompanion Premium includes a wide range of tools for working with PDF files. You can merge and split documents, rotate pages, add watermarks, create searchable PDFs with OCR, convert files to PDF/A, compare revisions, extract pages, optimize files, and more.
These tools make it easier to prepare, organize, review, and archive PDF documents without using a separate PDF application.
