Many users encounter the issue of "PDF version incompatibility" when submitting materials, connecting systems, or archiving documents long-term. For example, the recipient may only accept PDF 1.5, PDF 1.6, PDF 1.7, or PDF 2.0. Manually saving each file one by one is not only time-consuming but also error-prone. This article, using the actual interface of the office software " HeSoft Doc Batch Tool ", clearly explains how to batch import PDF files, select the target version, and complete the conversion uniformly. After reading, you can quickly master the method for batch converting PDF file versions to 1.5, 1.6, 2.0, and other version numbers, reducing repetitive tasks and improving document processing efficiency.
In daily office work, inconsistent PDF file versions are a very common issue. For example, some business systems only support lower versions of PDF, some collaborators require submission of PDF 1.5, PDF 1.6, PDF 1.7, or PDF 2.0, and some archiving scenarios require specific PDF/A standards. If the number of files is small, manual processing can be barely managed; but once batch conversion is needed, manually saving each file not only has low efficiency but also easily leads to missed files or wrong version selection.
What this article aims to solve is the problem of batch converting PDF file versions to 1.5, 1.6, 2.0, or other version numbers. With the office software HeSoft Doc Batch Tool , you can import multiple PDFs at once, uniformly set the target version, and process them centrally, which is particularly suitable for batch file organization and standardized output.
Applicable Scenarios
If you are encountering the following situations, this article will be very helpful:
- The recipient's system prompts that the PDF version is too high or too low and cannot be uploaded.
- A batch of PDFs needs to be uniformly converted to PDF 1.5, PDF 1.6, PDF 1.7, or PDF 2.0.
- Conversion to standard versions like PDF/A-1a, PDF/A-1b, PDF/A-2a, PDF/A-2b, PDF/A-3a, PDF/A-4, etc., is required according to archiving specifications.
- The company needs to batch process PDF files like contracts, reports, manuals, scanned copies daily to reduce repetitive work.
- Document sources are complex with inconsistent versions, requiring unified output before distribution to clients or internal systems.
For administrative, legal, finance, archiving, project, operations, and other roles that frequently handle large volumes of documents, batch converting PDF versions is a very typical office need.
Effect Preview
Before Processing
After entering the PDF tools from the software homepage, you can see the "PDF to Other Version PDF" function entry. This entry indicates that the software supports directly adjusting the PDF file version, rather than converting PDF to other formats.


After entering the function, the first step is to add files for processing. In the interface, you can see buttons like "Add Files", "Import Files from Folder", "Clear", and file information such as name, path, extension, creation time, and modification time is displayed in a list format, convenient for you to verify that the import is correct.
After Processing
When setting processing options, the software provides various optional versions, including common ones like PDF 1.0, PDF 1.1, PDF 1.2, PDF 1.3, PDF 1.4, PDF 1.5, PDF 1.6, PDF 1.7, PDF 2.0, and also supports various standards like PDF/A, PDF/X, PDF/UA. After selecting the target version, you can proceed to set the save location and start batch processing.

After processing is complete, you will get a batch of PDF files with unified versions, more suitable for system uploads, document exchange, and long-term archiving.
Operation Steps
Step 1: Enter the "PDF to Other Version PDF" function
Open HeSoft Doc Batch Tool , select PDF Tools on the left side, then find and click "PDF to Other Version PDF" in the function list.

Purpose of this step: Enter the correct batch processing module to avoid choosing other format conversion functions like "PDF to Word", "PDF to Excel", "PDF to TXT".
Expected result: Enter the function's processing page, displaying a step-by-step workflow, such as "Select Records to Process", "Set Process Options", "Set Save Location", "Start Processing".
Step 2: Batch add PDF files that need version conversion
After entering the processing page, first import files in the "Select records to process" step. You can choose based on the actual situation:
- Add Files: Suitable for selecting several PDFs from different locations.
- Import Files from Folder: Suitable for importing a large number of PDFs from the same folder at once.

After importing, files will be displayed in the list, where you can view:
- File Name
- File Path
- Extension
- Creation Time
- Modification Time
If imported incorrectly, you can use "Clear" to re-add, or remove individual files via the delete operation on the right side of the list.
Purpose of this step: Collect all files requiring unified PDF version conversion into the task list at once.
Expected result: The list accurately displays all PDFs to be processed, with the record count matching the actual number of files. Then click "Next Step" to enter the version setting page.
Step 3: Select the target PDF version, such as 1.5, 1.6, 2.0
On the "Set Process Options" page, you can see multiple version options.

Common requirements are typically:
- PDF 1.5
- PDF 1.6
- PDF 1.7
- PDF 2.0
In the screenshot example, PDF 2.0 is selected. If your goal is to batch convert PDFs to 1.5 or 1.6, you just need to choose the corresponding version here.
In addition to conventional PDF versions, the page also shows standard versions like PDF/A-1a, PDF/A-1b, PDF/A-2a, PDF/A-2b, PDF/A-3a, PDF/A-3b, PDF/A-4, PDF/X-1a, PDF/X-3, PDF/UA-1. For users with archiving, printing, accessibility, or specific industry standard requirements, these options are also very practical.
Purpose of this step: Define the target standard for the output files, ensuring the converted PDFs meet system compatibility or archiving requirements.
Expected result: The target version is correctly selected, for example, PDF 1.5, PDF 1.6, or PDF 2.0, then click "Next Step" to continue.
Step 4: Set the save location and start batch processing
From the interface workflow, you can see that after version setting, there are two more steps: "Set Save Location" and "Start Processing". That is, after selecting the PDF version, continue following the workflow to set the output location, then execute the batch processing.
Purpose of this step: Designate a unified output directory for the converted PDF files, facilitating subsequent searching, uploading, or archiving.
Expected result: The software batch outputs the processed files according to your selected target PDF version.
Common Questions and Precautions
1. Should I choose PDF 1.5, 1.6, or 2.0?
The principle is simple: based on the recipient's requirements. If the other party explicitly specifies PDF 1.5, do not choose 1.6 or 2.0; if there are no special requirements, the decision can usually be made based on the business system's compatibility. Older systems often lean towards PDF 1.4, 1.5, or 1.6, while newer environments may accept PDF 1.7 or PDF 2.0.
2. When batch importing, is it better to use "Add Files" or "Import Files from Folder"?
If files are scattered in multiple locations, using "Add Files" is recommended; if files are already organized in the same directory, using "Import Files from Folder" is more efficient. This is also the core value of office software batch processing: reducing repetitive clicks.
3. Should I check the file list before converting?
It is recommended to check. Especially when batch processing dozens or hundreds of PDFs, confirming the names, paths, and record count first can avoid mistakenly processing irrelevant files.
4. What is the difference between PDF/A, PDF/X, and regular PDF versions?
Regular PDF 1.5, 1.6, 2.0 are more oriented towards version compatibility needs; PDF/A is more about long-term preservation and archiving; PDF/X is often used for printing-related scenarios; PDF/UA relates to accessibility reading. If the issue is simply "system only recognizes a certain PDF version", choosing a regular PDF version is usually sufficient.
5. Why is using batch processing software recommended over manually "Save As"?
Because processing one file manually is not difficult, what's difficult is the massive repetitive operation. The value of office software lies precisely in: batch import, unified settings, one-time processing. This not only saves time but also reduces the rate of manual operation errors.
Summary
When you need to batch convert PDF file versions to 1.5, 1.6, 2.0, or other version numbers, using HeSoft Doc Batch Tool will be much more efficient than manually processing one by one. The overall workflow is very clear: first enter the "PDF to Other Version PDF" function, then batch add files, next select the target version, and finally set the save location and start processing.
For office scenarios frequently dealing with documents like contracts, reports, archives, scanned copies, this batch processing method can significantly reduce repetitive labor and improve file standardization and delivery efficiency.
If you are currently troubled by PDF version incompatibility, system upload failures, or batch archiving requirements, it is recommended to follow the steps in this article directly, first test the target version with a small batch of files, then proceed with the large batch conversion, which will be more secure and efficient.
