Some software or devices may only support specific versions of PDF. Converting to an earlier version (e.g., PDF 1.4 or 1.5) ensures the file can be opened on older systems or devices. Moreover, certain institutions or platforms may require that submitted PDFs meet specific version restrictions (e.g., academic journals, government agencies, printing houses, etc.), which might mandate PDF versions 1.4 or 1.7. The following describes how to batch convert a large number of PDFs into specific PDF version formats to enhance document compatibility and feature support.
1. Usage Scenario
When you have hundreds or thousands of PDF files that need to be downgraded to be opened and viewed with older systems or software, or when these files need to be submitted to certain institutions or platforms that require a specific PDF version, you can batch convert these PDF files uniformly to various versions such as PDF 1.0/1.1/1.2/1.3/1.4/1.5/1.6/1.7/2.0.
