About PDF/A and CALS
PDF/A is an ISO-standardized version of PDF designed for long-term archiving. CALS (Computer-Aided Layout System) is a document format commonly used in technical documentation and publishing, particularly in aerospace and defense industries. Converting from PDF/A to CALS allows you to repurpose archived documents for use in systems that require the CALS format. Our tool simplifies this process, ensuring a smooth transition between these two important document standards.
