When it is necessary to preserve important files for a long time, the common PDF is convenient, but over time issues such as being unable to open or format errors may arise. In this case, the PDF/A format ensures that files can still be opened normally after long-term preservation. Government departments and hospitals most commonly use the PDF/A format. For example, documents such as policies, regulations, or examination reports that need to be preserved for decades, once converted to PDF/A, will not be affected even if future computer systems change, avoiding problems like being unable to open or garbled opening. Similarly, schools and research institutions also greatly need this format. Supervisors' academic papers and students' graduation theses are all intellectual assets that require long-term preservation. If saved in PDF/A format, when others consult them far into the future, what they browse and see will still be in the original appearance, without issues like missing fonts or misaligned layout. Simply put, if a document is particularly important, needs long-term preservation, or may serve as a reference, you should consider converting it to the PDF/A format. Although it looks similar to a regular PDF document, it actually puts a protective layer on the document content, enduring the long test of time. So how can we batch convert a large number of ordinary PDF documents into the PDF/A format? Here we introduce three steps to efficiently complete the format batch conversion, supporting multiple formats such as PDF/A-1a, PDF/A-1b, PDF/A-2a, PDF/A-2b, PDF/A-2u, PDF/A-3a, PDF/A-3b, PDF/A-3u, PDF/A-4, PDF/A-4e, PDF/A-4f.
1. Usage Scenarios
When there are many important PDF documents that need to be preserved for decades or longer, and when re-accessing them in the future, it is necessary to ensure that the file content, fonts, and layout formats remain completely intact. We can batch convert them into PDF/A format to ensure the lasting value, security, and compliance of information assets.
2. Operation Steps
Open 【 HeSoft Doc Batch Tool 】, select 【PDF Tools】-【Convert PDF to Other PDF Versions】.

【Add Files】Select and add the PDF documents that need to be converted to PDF/A version independently
【Import Files from Folder】Import all PDF documents in the selected folder.
You can view the imported files below.

Choose from various arbitrary PDF versions such as PDF/A-1a, PDF/A-1b, PDF/A-2a, PDF/A-2b, PDF/A-2u, etc., for conversion as needed.

After processing is complete, click the save location to view the successfully converted version of the PDF file.
