When PDF files come from different sources, version numbers may be inconsistent, causing trouble for uploading, archiving, reading, and delivery. This article focuses on the office need of "batch unifying PDF file versions" and provides a detailed explanation on how to use HeSoft Doc Batch Tool to perform version conversion on multiple PDFs. The tutorial includes pre-processing checks, selecting "PDF to Other PDF Versions" in the PDF tool, adding multiple files, choosing target versions like PDF 2.0 or PDF 1.5, PDF 1.6, setting the output location, and verifying the processing results with document properties. It is suitable for users in administration, archives, legal affairs, bidding, document organization, and other fields who need to batch process PDFs.
In enterprise office work, document organization, and file delivery, PDFs often come from multiple sources: some are exported from Word, docx, Excel, or PPT; some are generated from scanners; and some are downloaded from web pages or third-party systems. Due to different generation tools, the version numbers of the same batch of PDFs may not be consistent. In daily reading, you may not necessarily notice the differences, but when uploading to platforms, archiving systems, electronic review systems, or older readers, these differences might lead to file verification failures, preview anomalies, or requests for resubmission.
If you need to unify a batch of PDF files to the same version, such as converting all to PDF 2.0, or converting to PDF 1.5, PDF 1.6, PDF/A, etc., as required, you can accomplish this using batch processing. The following uses HeSoft Doc Batch Tool as an example, with screenshots to explain how to unify PDF file versions completely, from importing files and selecting the version to verifying the post-processing results.
Applicable Scenarios: Why Unify a Batch of PDF Versions
The essence of unifying PDF versions is to make files conform to a common specification, reducing uncertainty in subsequent circulation. The following scenarios are well-suited for batch PDF version conversion:
- Bid Document Organization: Bid documents may contain multiple PDFs such as contracts, qualifications, scanned copies, and brochures. To avoid recognition anomalies in the review system, version unification is often needed.
- Archive Filing: Archive departments have specifications for the long-term preservation of electronic documents, which may require specific PDF versions or PDF/A types.
- Legal Contract Delivery: Contract attachments come from different departments or external entities. Unifying the versions makes management and submission easier.
- Submission of Teaching or Research Materials: Thesis appendices, courseware materials, and report documents may need to meet platform requirements; otherwise, they risk being rejected during upload.
- Cross-System Compatibility: When files need to be opened on different computers, readers, or internal network systems, unifying to a suitable version can reduce compatibility risks.
Compared to single PDF editing software, the advantage of batch processing office software is that it can import multiple files at once, set the same processing rule uniformly, and output results centrally. For repetitive tasks with a large number of files, this method can significantly save time.
Effect Preview: Check Versions Before Processing, Confirm Changes After
In this example, the folder to be processed contains several PDF files. They are displayed as standard PDF icons, including services.pdf, The Safety of Mars Sample Return.pdf, the-crowdsourced-guide-to-learning.pdf, Voyager-Grand-Tour.pdf, etc. Without a batch tool, users would need to open and process them one by one.
To confirm the version status before processing, open services.pdf and view the document properties. The area highlighted with a red box in the screenshot shows the PDF version is 1.7 (Acrobat 8.x). This indicates the file is currently PDF 1.7. If the target specification requires PDF 2.0, a version conversion is needed.
After completing the batch processing, open services.pdf in the output directory again and view the document properties; you can see the PDF version has changed to 2.0. This comparison demonstrates that the conversion result is verifiable and is not simply copying the file or renaming it.
In practical use, you can verify any output file using the same method. If the target version selected was PDF 1.5 or PDF 1.6, then the document properties of the processed file should also display the corresponding version. Although the verification step is simple, it is very important for officially submitted files.
Steps: Detailed Tutorial for Batch Unification of PDF Versions
Step 1: Open the Software and Enter the PDF Tools Category
After launching HeSoft Doc Batch Tool , first look at the category navigation on the left. The interface contains multiple entries for office file processing, such as Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Image Tools, etc. This requirement is for PDFs, so click "PDF Tools".
In the PDF tools list, find "Convert PDF to Other Versions of PDF". In the screenshot, this function card is selected, showing the description "Batch convert PDF files to other versions of PDF". This is precisely the function we will use in this article.
The expected result of this step is to enter the correct processing module. Note that the interface also contains functions like "PDF to Word", "PDF to PowerPoint", "PDF to Excel", "PDF to JPG Images", etc., which are file format conversions; whereas "Convert PDF to Other Versions of PDF" output is still PDF, making it more suitable for unifying PDF version numbers.
Step 2: Add Files or Import from a Folder
After entering the function, the top of the page displays the current task as "Convert PDF to Other Versions of PDF". The process bar shows four stages: Select records to process, Set processing options, Set save location, Start processing. You are currently in the first stage and need to add the PDFs to be processed to the list.
If the number of files is small, you can click "Add Files" to select multiple PDFs; if all files are in the same directory, clicking "Import Files from Folder" is more convenient. In the example, 4 files have already been imported, and the list shows the name, path, extension, creation time, and modification time for each file.
It is recommended to develop a checking habit here: first, check if the record count at the bottom is correct; second, check if the file paths come from the target folder; finally, see if the extension is pdf. Since batch processing will execute the same rule for all records in the list once started, preliminary checks can reduce subsequent rework.
Step 3: Select the Target PDF Version for Unification
Clicking "Next Step" enters the section for setting processing options. The interface uses "Version" as a grouping and provides various choices. Standard versions include 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; it also offers types like PDF/A, PDF/X, PDF/UA, ZUGFeRD.
In this example, PDF 2.0 is selected, with a red box and arrow pointing to this option. After selection, the software will process all PDFs imported in the previous step according to this target version. That means, if there are 4 PDFs in the list, they will all be uniformly converted to PDF 2.0; if there are more files in the list, they will also be processed with the same rule.
When choosing a version, you can refer to these ideas: if the platform requires PDF 2.0, choose PDF 2.0; if compatibility with an older environment is needed, PDF 1.5 or PDF 1.6 might be chosen; if an archival standard is required, select the relevant PDF/A option based on the requirement. Do not switch standard types arbitrarily without a requirement, especially when it involves long-term archiving, printing, or accessibility standards; the specification document should prevail.
Step 4: Set the Save Location to Generate Clear Output Results
The third step in the process bar is "Set Save Location". Although the screenshot does not show the specific controls on this page, the document properties after processing indicate that the output location is under the hesoft-output folder on the desktop. This means the converted files are saved in an output directory, not just viewable in their original location.
It is recommended to use a separate output folder in this step and to indicate the target version in the name. For example: PDF_2.0_Output, PDF_1.6_Compatible_Version, PDF_A_Archive_Version. Doing this ensures the original files, converted files, and final submission files remain clearly separated. For office team collaboration, clear folder naming also reduces the risk of mistakenly sending old files.
Step 5: Start Processing and Conduct Spot Checks
After completing the save location settings, proceed to "Start Processing". Confirm three things at this point: whether the file list is correct; whether the target version is correct; whether the save location is correct. After confirmation, execute the batch processing. Once processing is complete, open the output directory to view the generated PDF files.
When doing spot checks, it is recommended to check from three angles: first, whether all files have been generated; second, whether the page count is correct and the content is complete after opening; third, whether the PDF version in the document properties matches the target. This article's example has verified, through before-and-after screenshots, that services.pdf was converted from PDF 1.7 to PDF 2.0.
Common Questions or Notes
1. Can the original files be retained after unifying the PDF version?
It is recommended to keep the original files. From the post-processing screenshots, you can see the resulting files are located in an output directory, a method that helps distinguish original files from new files. Before formal batch processing, it is best not to delete the originals directly, so you can reprocess them if the target version is incorrectly selected or if requirements from the other party change.
2. Can PDFs with different versions in a batch be processed together?
Yes, they can be processed according to the same target version. The purpose of batch importing is to allow PDFs from different sources and possibly different versions to be converted under a unified rule. After processing, spot-check the output results to confirm the versions have been unified.
3. What is the difference between converting PDF to another version and converting PDF to Word?
PDF to Word converts PDF into an editable document, with the typical output possibly being docx or doc; PDF to Excel outputs a spreadsheet file; whereas converting PDF to another version of PDF still outputs PDF, but the version or standard type changes. Therefore, if your goal is to meet PDF version requirements, you should choose the function described in this article.
4. Why is it sometimes necessary to convert to a lower version?
Higher versions are not necessarily suitable for all scenarios. Older readers, legacy business systems, or certain embedded preview components might not fully support high-version PDFs. When encountering compatibility issues, converting files to PDF 1.5 or PDF 1.6 may be more suitable for the actual environment.
5. Is it necessary to check every file individually after conversion?
When the number of files is very large, it may not be necessary to open each one individually, but spot checks are recommended before formal submission. Focus on checking PDFs from different sources, with many pages, containing scanned images, forms, or special content. If the submission platform has a verification feature, you can also try uploading a small number of files first to confirm they are correct before submitting the entire batch.
Summary: It is More Efficient to Entrust PDF Version Unification to a Batch Processing Tool
Batch unification of PDF versions is a typical office efficiency problem. It is not difficult, but if done manually, it consumes a lot of time and is prone to omissions. Using HeSoft Doc Batch Tool , you can use the "PDF Tools — Convert PDF to Other Versions of PDF" workflow to import multiple files at once, uniformly select PDF 1.5, PDF 1.6, PDF 2.0, or another target version, and then output them centrally.
If you are organizing a batch of PDFs that need to be uploaded, archived, submitted, or delivered, it is recommended to first check the requirements of the other party, determine the target version, and then perform the batch conversion following the steps in this article. After completion, spot-check the results via document properties to confirm that the version and content are normal. This can reduce repetitive work and improve the standardization and reliability of file delivery.
