When filing systems, audit projects, or contract archiving require submission of standard formats such as PDF/A-1a or PDF/A-1b, converting PDFs one by one consumes a significant amount of time. This article uses HeSoft Doc Batch Tool as an example to illustrate how to select "Convert PDF to other PDF versions" in a PDF tool, batch-add PDF files, uniformly choose the PDF/A version, and complete the save location and processing flow. The article also introduces the differences before and after processing, applicable scenarios, and precautions, helping office users complete file archiving in a more standardized manner.
Many organizations encounter a practical issue when managing electronic archives: the materials they have already organized are regular PDFs, but archive submission standards require PDF/A-1a, PDF/A-1b, PDF/A-2a, or other PDF/A versions. Particularly for documents like contracts, audit reports, ISO certification materials, annual reports, and legal instruments, once the volume is substantial, manually converting them one by one is not only slow but also prone to issues like omissions, selecting the wrong version, and disorganized save locations.
This article addresses the problem of "how to uniformly convert multiple PDF files into PDF/A archival format." We will use HeSoft Doc Batch Tool to complete the operation. It is an office document batch processing software, whose product positioning is not simply opening files, but helping users process files in batches, reduce repetitive work, and improve file organization efficiency. Through its PDF tools, a batch of PDFs can be converted into a specified PDF version at once, including various PDF/A standards.
Applicable Scenarios: Office Tasks Requiring a Unified PDF/A Version
In practical office work, PDF/A conversion is typically not a personal preference but dictated by archiving, submission, or institutional requirements. The following scenarios are particularly suitable for batch processing:
- Archive Transfer: A department needs to submit a batch of electronic files to the archives office, requiring a unified PDF/A format.
- Audit Projects: Audit workpapers, financial materials, annual reports, etc., require long-term preservation and demand stable file formats.
- Contract Archiving: Client agreements, procurement contracts, supplementary agreements, authorization documents, etc., need to be kept uniformly.
- Compliance Material Submission: Certification documents, institutional documents, legal documents, etc., need to meet specified PDF/A version requirements.
- Standardization of Historical Files: PDF versions from multiple sources are inconsistent and need to be batch-converted to the same PDF/A standard.
The difficulty with these tasks lies in the large number of files and the need for a uniform standard. If handled manually one by one, it's not only inefficient but also difficult to ensure each file has the same version selected. Using HeSoft Doc Batch Tool allows the same batch of files to go through an identical processing workflow, reducing human discrepancies.
Preview of Results: The Difference Between Regular PDF and PDF/A Archival Files
Before Processing: Your files might be scattered across the desktop, project folders, or shared directories. The file extensions are all .pdf, but the internal PDF versions may differ. Some files come from scanners, while others originate from Word, doc, docx, Excel, PPT, or system exports, resulting in inconsistent generation standards.
After Processing: All selected PDFs will be output as PDF/A-type PDF files according to the same target version. For example, if you select PDF/A-1a, then all files in this batch will be converted towards the PDF/A-1a standard; if you choose PDF/A-2b, they will be uniformly converted to the corresponding version. This makes it easier for the archive system to receive, for file list verification, and for subsequent long-term preservation.
It should be noted that PDF/A files typically still use .pdf as the extension, so processed files may not directly reflect PDF/A from the filename. The actual difference lies in the internal file standard, not a change in the extension.
Operation Steps: Batch Convert PDFs to a Specified PDF/A Version
Step One: Find the Conversion Entry in PDF Tools
After launching HeSoft Doc Batch Tool , first look at the left navigation bar. The screenshot shows the left side contains categories like Home, Task Flows, All Tools, File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, etc. To handle PDF/A conversion, you should click "PDF Tools."
After entering PDF Tools, select "Convert PDF to other PDF versions" from the function cards on the right. This entry is not for converting PDF to docx, Pptx, TXT, Excel, or JPG images, but for converting a PDF to another PDF version, thus making it suitable for PDF/A conversion.
Operation Purpose: Enter the correct PDF version conversion function.
Expected Result: The software opens the "Convert PDF to other PDF versions" wizard page.
Step Two: Add Individual Files or Import PDFs from a Folder
At the top of the wizard page, you can see the current function name "Convert PDF to other PDF versions." The first step on the page is "Select records to process." In the upper right corner are the "Add Files" and "Import files from folder" buttons. For a small number of files, you can click "Add Files"; for batch archiving tasks, it's more recommended to first place the files into a folder and then use "Import files from folder."
After importing, the table lists the file sequence number, name, path, extension, creation time, modification time, and actions. Through these columns, you can verify if all are PDF files and if the paths come from the correct folder. The sample list in the screenshot includes files like Annual_Report_2024.pdf, Audit_Report_Company_Y_2024.pdf, Contract_Agreement_Client_X.pdf, and shows a record count of 8 at the bottom.
Operation Purpose: Add all files that need to be converted to PDF/A into the same task list.
Expected Result: The list displays the files to be processed, with the record count matching the actual number of files.
If any file was imported by mistake, it can be removed via the delete icon on the right side of each row; if the entire list is wrong, you can click "Clear" and re-import. Completing the check before the official conversion prevents unrelated files from being mixed into the processing results.
Step Three: Click Next and Select the PDF/A Version
After confirming the file list is correct, click "Next" at the bottom to enter "Set processing options." The key area on this page is "Version." As seen in the screenshot, the software provides various PDF/A options, including 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, etc., alongside PDF/UA-1, PDF/X-1a, PDF/X-3, ZUGFeRD, and versions like PDF 1.0 through PDF 2.0.
If your task is file archiving, focus on the options starting with PDF/A. In the screenshot, PDF/A-1a is already selected. You can choose PDF/A-1a, PDF/A-1b, or another specified version based on the requirement. After selection, click "Next" to continue.
Operation Purpose: Specify to which PDF/A standard this batch of PDFs should be uniformly converted.
Expected Result: The target PDF/A version is selected, and the batch task will process according to this standard.
Step Four: Set the Output File Save Location
The top of the wizard shows the third step as "Set save location." Although the screenshot doesn't show the details of this page, it is clear from the workflow that the save location for the conversion results needs to be set before starting the process. It is recommended to set the output location to an independent folder, such as "PDFA Output," "Archival Version PDF," or a project name plus date folder. This has two benefits: first, it makes it easy to distinguish between source files and result files; second, it facilitates subsequent quantity checks, packaging for submission, or importing into the archive system.
Operation Purpose: Centralize the converted PDF/A files for saving, avoiding mixing with the original files.
Expected Result: The output directory is determined, ready to enter the final processing step.
Step Five: Start Processing and Verify the Output
After setting the save location, enter the "Start processing" phase. It is advisable to confirm three pieces of information again before starting: whether the file list is correct, whether the version is selected as the required PDF/A standard, and whether the save location is appropriate. After confirmation, execute the processing. Once processing is complete, go to the output folder, verify that the file count matches the imported records, and spot-check a few files to ensure they can be opened normally.
Operation Purpose: Batch-generate PDF/A files that meet the requirements.
Expected Result: A batch of regular PDFs is uniformly converted to the specified PDF/A version, ready for archiving or submission.
Common Questions or Precautions
1. How to choose between PDF/A-1a, PDF/A-1b, PDF/A-2a?
Version selection should be based on the recipient's requirements. If the archives office, client, auditing body, or system documentation explicitly states PDF/A-1a, select PDF/A-1a; if it requires PDF/A-1b, select PDF/A-1b. Do not change the version arbitrarily without confirmation.
2. Why isn't the function name "PDF to PDF/A"?
The function name in the screenshot is "Convert PDF to other PDF versions." PDF/A is a standard version of PDF, hence it's included under the "other PDF versions" option. Once inside, you can select PDF/A related options in the "Version" area.
3. Is it necessary to check the list after importing from a folder?
Yes, it is. Batch processing is very efficient, but only if the task list is correct. It is recommended to check the extensions, filenames, and paths to confirm that no temporary files, duplicate files, or irrelevant PDFs were imported by mistake.
4. Can the converted files still be opened like regular PDFs?
Generally, they can still be opened and read as PDFs. The focus of PDF/A is long-term preservation and standardization, not changing the file extension or converting the file into editable formats like Word or Excel.
5. What are the recommendations before processing important materials?
It is recommended to keep the original files and save the output results to a separate directory. For important materials like contracts, financial data, audit reports, and legal documents, spot checks should be performed after processing, and if necessary, an archiving system or professional tools should be used to verify PDF/A compliance.
Summary: A Unified Version is More Suitable for Batch Archiving than Individual Conversion
When multiple PDF files need to be uniformly converted to PDF/A-1a, PDF/A-1b, or other PDF/A versions, the most important thing is ensuring that the batch files are processed under the same rules. HeSoft Doc Batch Tool , through a clear wizard process, breaks down "select files, set version, set save location, start processing" into several steps, allowing office workers to complete batch conversion without repeatedly opening each PDF.
If you are currently organizing electronic archives, audit materials, or contract files, you can first clarify the target PDF/A version, then place the PDFs needing processing into a single folder, use the "Import files from folder" function to add them in bulk, and finally convert them uniformly. This can reduce repetitive work and improve the standardization and traceability of file archiving.
