This article introduces how to use HeSoft Doc Batch Tool to automatically extract barcode numbers from multiple PDF files and batch rename them as PDF file names. It is suitable for organizing PDF files with barcodes or barcode numbers such as contracts, invoices, logistics orders, inspection reports, and archival documents. By importing files, selecting "Rename PDF files using file content", and setting the search area to "First barcode image", you can batch rename originally meaningless file names like 1.pdf, 2.pdf into barcode-corresponding numbers, reducing the repetitive labor of manually opening, identifying, and renaming each file.
When organizing a large number of PDF files, one of the most troublesome things is that "the file names are meaningless." For example, scanned PDFs might simply be named sequentially as 1.pdf, 2.pdf, 3.pdf, 4.pdf, but the number actually used for archiving, retrieval, or handover is printed below the barcode within the PDF content. Manual processing requires opening each PDF, zooming into the page, checking the barcode text, and then returning to the folder to rename the file. This can be managed when there are only a few files, but once you have dozens or hundreds of PDFs, this repetitive work becomes very time-consuming and is prone to errors like misreading numbers, missing digits during copying, or inconsistent naming.
This article addresses this specific scenario: using the barcode text in PDF content to batch rename the PDF files. Through the batch file processing capabilities in office software like HeSoft Doc Batch Tool , the software can be set to automatically read the first barcode image in a PDF and use the recognized barcode number as the new PDF file name. In this way, the work that originally required manually opening and modifying each file one by one can be completed through centralized importing, unified settings, and batch processing, making it more suitable for high-frequency file processing tasks like office archiving, document sorting, and scanned document management.
Applicable Scenarios: Which PDFs Are Suitable for Batch Renaming by Barcode Text
Renaming based on barcode numbers within PDF content is suitable for all situations where "there is a clear identification number in the file content, but the file name is not standardized." Examples include logistics waybills, freight documents, warehouse receipts, inspection reports, equipment documentation, certificate archives, internal process forms, and customer data packages. These types of PDFs usually have a barcode placed somewhere on the page, and below or within the barcode itself corresponds to a string of numbers or characters. As long as a barcode number usable for naming can be extracted from each PDF, it can serve as part or all of the file name.
As seen in the screenshot, the folder before processing contains 4 PDF files, with simple numeric sequential file names: 1.pdf, 2.pdf, 3.pdf, 4.pdf. This naming method only indicates file order and cannot directly convey the file's corresponding business number, barcode number, or document ID. For future retrieval, users would still need to open the file to understand its specific content.
Opening one of the PDFs, you can see a barcode in the upper right corner of the page, with the number "20036655" displayed below it. This is exactly the content we hope to extract for the file name. This means that while a file's original name might be 2.pdf, its truly identifying name should be the barcode number 20036655.pdf.
Result Preview: How File Names Change Before and After Processing
Before processing, the PDF file names are 1.pdf, 2.pdf, 3.pdf, 4.pdf. Such file names often originate from scanning software, export systems, or batch download results, only indicating the order of file generation and not reflecting the internal content of the PDFs. If these files need to be handed over to colleagues, uploaded to a system, or archived long-term, the lack of readability in the file names increases the cost of future retrieval.
After processing with the "Rename PDF files using file content" feature, the file names are batch-changed to the corresponding barcode numbers. For example, the screenshot shows the processed file names changed to 10026877.pdf, 20036655.pdf, 20100511.pdf, 33952100.pdf. Each PDF file's name directly corresponds to the barcode text within its content, eliminating the need to open the PDF to confirm the file's identity.
The value of this result is straightforward: the file name itself becomes a searchable business ID. Subsequently, whether searching in a Windows folder, copying to a colleague, uploading to a business system, or performing secondary organization, files can be located directly by their ID number, saving a significant amount of manual verification time.
Operating Steps: Batch Renaming Using the First Barcode Image in PDFs
Following the process shown in the screenshots, here is how to perform batch renaming of PDFs by barcode in HeSoft Doc Batch Tool . This software is positioned as a batch office document processing tool, with its core advantage being the centralized handling of repetitive, mechanical, and error-prone file operations, particularly suitable for batch organizing PDF, Word, Excel, PowerPoint, text, and image files.
Step 1: Go to the "File Name" category and select the PDF content renaming function
After opening HeSoft Doc Batch Tool , select "File Name" from the function category list on the left. Find "Rename PDF files using file content" in the function list. The description on this function card in the screenshot says "Batch use certain text from PDF file content as the file name," which aligns perfectly with our goal here: using the barcode number inside the PDF as the PDF file name.
It is important to note not to select common functions like "Find and replace keywords in file names" or "Add prefix and suffix to file names," as those primarily work on the existing file name itself. What we are dealing with here is "text within the PDF content." If the barcode number is not in the current file name but inside the PDF page, you should choose "Rename PDF files using file content."
Step 2: Add the PDF files to be processed
After entering the function page, the top displays the current function name "Rename PDF files using file content," and the process is divided into stages: "Select records to process, Set processing options, Set save location, Start processing." The first step is to import the PDFs to be processed into the list. In the upper right corner of the interface, you can see two entry points: "Add Files" and "Import Files from Folder." If processing only a few specific PDFs, you can choose to add files; if a large number of PDFs in the same folder need to be handled uniformly, you can import files from the folder.
After importing, the software will display the file records in a list, including information such as sequence number, name, path, extension, creation time, and modification time. In the screenshot, 4 PDF files have been imported, named 1.pdf, 2.pdf, 3.pdf, 4.pdf respectively, located in a test directory on the D drive, all with the .pdf extension. After confirming the file list is correct, click "Next" at the bottom to proceed to the processing options settings.
The purpose of this step is to let the software know which PDF files need batch processing. The expected result is that all PDFs requiring renaming appear in the list, with the count matching the actual number of files to be processed. If files not needing processing are mistakenly imported, they can be removed using the operation column in the interface; if files are missing, they can be supplemented using the add entry point.
Step 3: Set the search area to "First Barcode Image"
In the second step, "Set processing options," the interface provides search area options, including "First line of text," "First barcode image," and "Text matched by custom formula." The goal of this tutorial is to read the barcode number from the PDF, so "First barcode image" must be selected. The screenshot highlights this option with a red box, and it is checked.
Selecting "First barcode image" means the software will search for the first barcode image in each PDF's content and use the recognized barcode content to generate the file name. This setting is ideal for PDFs that have only one barcode per page, or where the first barcode number on the page should be used as the file identifier.
If your PDF files should be named not by a barcode number but by the first line of text on the page, then you would consider "First line of text." If you need to match a specific text segment on the page according to certain rules, you might use "Text matched by custom formula." However, for the scenario shown in this article's screenshots, where a barcode exists on the PDF page and its number is the basis for naming, choosing "First barcode image" is the most direct setting.
Step 4: Choose the position rule for the new file name
On the same settings page, you can also see a "Position" option, including "Overwrite the entire file name," "To the left of the file name," and "To the right of the file name." The screenshot shows "Overwrite the entire file name" is selected. This means the recognized barcode number will directly replace the original main part of the file name. For instance, if the original file name is 2.pdf and the recognized barcode number is 20036655, after processing it will become 20036655.pdf.
If you want to use the barcode number entirely as the PDF file name, selecting "Overwrite the entire file name" is recommended. This makes the file name cleaner, suitable for scenarios where the barcode number is the sole basis for retrieval. If you need to keep the original file name as a reference in the future, you can use the position options provided in the interface to place the recognized content to the left or right of the file name. However, judging by the processing result in this article, the final outcome has the number directly as the file name, so using "Overwrite the entire file name" is appropriate.
Step 5: Continue to set the save location and start processing
After completing the search area and position settings, click "Next" at the bottom. The progress bar indicates that "Set save location" and "Start processing" remain. Since the screenshots mainly show the file importing and processing options settings, the subsequent steps can be completed by following the prompts on the software page. Usually, when batch processing files, it is advisable to first confirm the save location to avoid confusing the processing results with the original files; once confirmed, then proceed to the start processing stage.
After processing is complete, navigate to the save location to view the results. The expected effect is as shown in the after-processing screenshot: the original 1.pdf, 2.pdf, 3.pdf, 4.pdf no longer appear as simple sequential numbers but become PDF file names corresponding to their barcode numbers. Thus, a batch of PDFs has been reorganized from "meaningless sequential naming" to "content-based numerical naming."
Frequently Asked Questions and Notes
1. Why is it important to first check if the barcode in the PDF is clear?
Barcode recognition depends on the image quality of the barcode in the PDF page. If the barcode is blurry, severely skewed, obstructed, or has low scanning resolution, it can affect the recognition result. Before batch processing, it is recommended to spot-check a few PDFs to ensure the barcode and the number below it are clearly visible on the page.
2. What if a PDF has multiple barcodes?
The setting in the screenshot is "First barcode image," suitable for cases where each PDF should be named after its first barcode. If a file contains multiple barcodes, you need to first verify that the first one is indeed the number you want to use for naming to avoid recognizing a barcode intended for another purpose.
3. What is the impact of duplicate barcode numbers?
If multiple PDFs are identified with the same barcode number and the option to overwrite the entire file name is chosen, duplicate file names could occur. Before batch processing, you should confirm whether business numbers are unique, especially in scenarios like invoices, waybills, and inspection reports, where duplicate numbers must be investigated beforehand.
4. Can Word, docx, or doc files be processed?
This article describes renaming PDF files by content, corresponding to the function "Rename PDF files using file content." As seen in the software interface, similar functions also include "Rename Word files using file content," suitable for scenarios where Word documents, docx, doc, etc., are named based on their content. In practice, the corresponding function should be selected based on the file type.
5. Is a backup needed before processing?
Batch renaming is a batch file operation. It is recommended to keep a backup of the original files before official processing, or first use a small sample to test whether the settings meet expectations. After confirming that barcode recognition, naming position, and saved results are all correct, process the entire folder.
Summary: Let PDF File Names Directly Correspond to Barcode Numbers to Reduce Repetitive Organization
Using the barcode text in PDF content to batch rename PDF files essentially hands the repetitive task of "opening a file to check a number and then manually renaming it" over to the office software for automatic completion. Through the "Rename PDF files using file content" function in HeSoft Doc Batch Tool , you can batch import PDFs, select "First barcode image" as the search area, and have the recognized number overwrite the original file name to become the new one.
For users who need to organize scanned documents, receipts, reports, logistics files, and archival materials over the long term, this batch processing method significantly reduces manual operation time and minimizes errors caused by copy-pasting and manual input. It is advisable to first select a few PDFs for testing in practical work, confirming that the barcode numbers can correctly become file names, and then batch process the entire folder. This approach is both safe and efficient.
