In the modern digital environment, long-term archiving of documents in a reliable and standardized format is critical for businesses, governments, and institutions. PDF/A (Portable Document Format for Archiving) is an ISO-standardized version of PDF specifically designed for digital preservation. It ensures that documents can be reproduced exactly the same way in the future, by embedding all necessary information such as fonts, color profiles, and metadata.
If you have a diverse range of source files—including PostScript (PS), image formats (such as TIFF, JPEG, PNG), and standard PDF files—and need to convert them into PDF/A format, you will need a robust suite of tools. VeryPDF and VeryDOC offer a set of command-line utilities that make this process highly efficient and customizable.
Step 1: Convert PostScript Files to PDF Using VeryDOC Postscript to PDF Converter
PostScript files are often used in the printing industry and document processing workflows. Before these can be converted to PDF/A, they must first be converted to standard PDF format.
Tool Required: VeryDOC Postscript to PDF Converter Command Line
Key Features:
-
Converts PostScript (.ps) and Encapsulated PostScript (.eps) to PDF.
-
Supports batch processing of multiple PS files.
-
Allows setting of output PDF properties such as resolution and paper size.
Example Usage:
ps2pdf.exe input.ps output.pdf
This step ensures your PostScript documents are transformed into a usable PDF format, paving the way for the next stage—PDF/A conversion.
Step 2: Convert Image Files to PDF Using VeryPDF Image to PDF Converter Command Line
For scanned documents or image-based files, you need to convert them into PDF format before applying PDF/A standards.
Tool Required: VeryPDF Image to PDF Converter Command Line

Command-line interface suitable for batch operations and automation.
Example Usage:
img2pdf.exe -r 300 -o output.pdf image1.tif image2.tif
This command converts one or more image files into a high-resolution PDF. Optional OCR functionality can be added if text recognition is required.
Step 3: Convert PDF Files to PDF/A Using VeryDOC PDF to PDF/A Converter
Once you have your documents in standard PDF format—whether from PostScript or image sources—you are ready for the final step: converting them to PDF/A.
