If the PDF file contains a barcode number but the file name is still meaningless like 1.pdf, 2.pdf, you can use HeSoft Doc Batch Tool to batch rename based on file content. This article focuses on the scenario of "extracting barcode text from PDFs as file names," explaining the before-and-after effects, applicable business scenarios, and detailed operation procedures. Users simply need to import PDF files, select "First Barcode Image" in the processing options, and set it to overwrite the entire file name, allowing PDFs to be automatically renamed with barcode numbers, improving file archiving and retrieval efficiency.
Many office scenarios encounter the same problem: the actual number of a PDF file is within the page content, but the file name is just a system-generated sequence number. For example, with scanned contracts, express waybills, reports, archive covers, and inbound/outbound documents, the PDF page may have a clear barcode and number, but what you see in the folder are 1.pdf, 2.pdf, 3.pdf. To organize these PDFs into searchable materials, the traditional approach is to open each PDF one by one, check the barcode text, and then go back to the folder to modify the file name. This process seems simple, but it is actually very time-consuming, especially as the number of files increases, and the accuracy of manual operation will decrease.
This article introduces a more suitable approach for batch office work: extracting barcode text from PDFs as file names and automatically naming PDF files in bulk. With the help of HeSoft Doc Batch Tool , the first barcode image in the PDF content can be used as the recognition source, and the identified barcode number can directly overwrite the original file name. In this way, the originally irregular PDF names will be batch-changed to business numbers, facilitating subsequent archiving, searching, verification, and delivery.
Applicable Scenario: Extracting Barcode Numbers from PDF Content to Name Files
This method is particularly suitable when the file itself already contains a unique number, but the file name does not sync with this number. Common examples include logistics slip PDFs, order document PDFs, inspection report PDFs, asset data PDFs, certificate PDFs, warehouse label PDFs, and exam or training material PDFs. As long as each PDF contains an identifiable barcode and the text number corresponding to that barcode can be used as the file name, this batch renaming method can be considered.
From the pre-processing screenshot, there are 4 PDF files in the folder, named very simply as 1.pdf, 2.pdf, 3.pdf, 4.pdf. Such file names might be acceptable during temporary processing, but once they enter official archiving or when you need to find a specific PDF among a large amount of data, it will be very inconvenient. Users cannot determine which number each PDF corresponds to by its file name, nor can they directly search for the target file using the business number.
After opening one of the PDFs, you can see that there is a barcode in the upper right corner of the PDF page, with the number 20036655 displayed below the barcode. This indicates that the PDF content already contains key information that can identify the file's identity, but this information has not yet been reflected in the file name. The operational goal of this article is to extract this type of barcode text so that the PDF file name automatically becomes something like 20036655.pdf.
Result Preview: PDF Files are Easier to Search After Automatic Naming
After the batch processing is completed, the PDF file names change from the original sequential numbers to barcode numbers. In the post-processing screenshot, you can see that the original 4 PDFs have become 10026877.pdf, 20036655.pdf, 20100511.pdf, and 33952100.pdf. Each file name is no longer a meaningless sequence, but directly corresponds to the barcode number in the PDF content.
The advantages of this naming method are obvious. First, the file name becomes readable, searchable, and verifiable, allowing users to know which number it corresponds to without opening the file. Second, when uploading PDFs to a business system or handing over materials to colleagues, the file name itself conveys key information, reducing communication costs. Third, if you need to find a certain number later, you can locate the file by searching the barcode digits in the folder, without having to open each PDF one by one to check.
Operation Steps: Batch Extract PDF Barcode Text and Rename
Below, combined with screenshots of software operations, we explain how to use HeSoft Doc Batch Tool to complete this task. This software is an office document batch processing tool suitable for handling large volumes of repetitive file organization needs, such as batch file renaming, naming by content, folder organization, and batch processing of different types of office documents. This article focuses on using its PDF-related file name processing function.
Step 1: Find PDF Content Renaming in the File Name Tool
After opening the software, select "File Name" in the navigation bar on the left. The main area will display multiple functions related to file name processing, such as replacing file name keywords, inserting text, adding prefixes/suffixes, and renaming using file content. What we need to use in this article is "Rename PDF Files Using File Content". In the screenshot, this function card is selected, with the description text "Batch use certain text in the PDF file content as the file name of that file".
The reason for choosing this function is that the barcode number is not in the original file name, but in the PDF page content. If you only do a find-and-replace on the existing file name, you cannot get the barcode number inside the PDF. Therefore, it is necessary to use the "rename by file content" approach, allowing the software to read information from the PDF and then generate a new file name.
Step 2: Import PDF Files That Need Automatic Naming
After entering the function, the top of the page displays "Rename PDF Files Using File Content", and the process is divided into four stages: Select Records to Process, Set Processing Options, Set Save Location, and Start Processing. The task of the first stage is to import the PDFs to be processed. The upper right part of the interface provides "Add File" and "Import Files from Folder" buttons, allowing users to choose the import method based on the number of files.
After importing, the list will display the name, path, extension, creation time, and modification time of each PDF. As seen in the screenshot, four files—1.pdf, 2.pdf, 3.pdf, 4.pdf—have been imported, all with pdf extensions. The summary area at the bottom shows the record count is 4, indicating that this batch will process 4 PDFs. After confirming no wrong files were imported, click the "Next" button at the bottom of the page to enter the option settings.
The key to this step is to ensure the list of pending files is accurate. If the folder contains PDFs that should not be renamed, they should be excluded before starting processing; if any files are missing, they should be added. The efficiency of batch tools comes from one-time processing, but the premise is that the input list is correct.
Step 3: Select "First Barcode Image" in the Search Area
After entering the second stage, "Set Processing Options", you need to tell the software from which location or type of content in the PDF to extract the file name. The screenshot shows three options in the "Search Area": First line of text, First barcode image, Text matched by custom formula. This tutorial aims to extract PDF barcode text, so "First barcode image" should be selected.
After selecting this option, the software will use the first barcode image in each PDF as the recognition target and use its corresponding content for naming. Combining with the previous PDF preview, the number 20036655 is below the barcode, so the corresponding file in the processing result will be named 20036655.pdf. For materials where the barcode position is fixed and each PDF has only one main barcode, this option can effectively reduce manual identification work.
If the number is the first line of text on the first page of your PDF, you can choose "First line of text"; if the number needs to be matched from the body text according to a certain fixed format, you can consider "Text matched by custom formula". But in the barcode naming scenario shown in the current screenshot, "First barcode image" is the most appropriate setting.
Step 4: Set the Position of the Barcode Number in the File Name
The same page also has "Position" settings, offering three options: "Overwrite Entire File Name", "On the Left Side of File Name", and "On the Right Side of File Name". The screenshot shows "Overwrite Entire File Name" is selected, meaning the identified barcode number will directly replace the main part of the original file name.
For example, if the original file name is 2.pdf, and the barcode number in the PDF is 20036655, after overwriting the entire file name, the new file name will be 20036655.pdf. This method is suitable for archiving scenarios where the barcode number serves as the unique file identifier, resulting in concise and uniform file names that are easy to search later. If users wish to retain the original file name, they can also choose to place the identified content on the left or right side of the file name according to actual needs, but the final effect shown in this article is complete naming using the barcode number.
Step 5: Continue to the Next Step, Confirm Save Location, and Execute Processing
After completing the search area and position settings, click "Next". From the process bar, you can see that the subsequent steps include "Set Save Location" and "Start Processing". Although the screenshot does not expand the latter two pages, according to the interface flow, the user needs to continue following the software prompts to confirm the result save location and then start batch processing.
Before official execution, it is recommended to first confirm a few key points: Is the number of PDFs in the import list correct? Is "First barcode image" selected in the search area? Is the position "Overwrite Entire File Name"? Does the save location conform to your file management habits? Confirming these before starting can reduce rework.
After processing is complete, check the files in the save location. The expected result matches the effect diagram: PDF files will be automatically named according to the barcode numbers in their respective content, eliminating the need for manual opening, viewing, and modification one by one.
Common Questions and Precautions
1. Does the barcode in the PDF have to be on the first page?
The barcode shown in the screenshot is located in the PDF page content, and the function option is "First barcode image". In actual use, you should first confirm that the software can recognize the barcode you intend to use. If the barcode position and sequence are consistent across each PDF, the batch processing result will be more stable.
2. Are the numbers below the barcode and the file name exactly the same?
From the example effect, the barcode number in the PDF will be used to generate the file name, for example, 20036655 ultimately becomes 20036655.pdf. Before processing, you can test with a small sample to confirm that the recognition result matches the number displayed on the page, and then batch process all PDFs.
3. Will the original file name be preserved?
If "Overwrite Entire File Name" is selected, the new file name will replace the original file name body with the identified barcode number. If you wish to keep the original file name information, you can use the position options on the interface to add the identified content to the left or right side of the file name. Which method you choose depends on your archiving rules.
4. Can this be used for other file formats?
This article demonstrates PDF files, so "Rename PDF Files Using File Content" was chosen. If you need to rename Word files (such as docx, doc documents) by content, you should use the corresponding Word content renaming function in the software. You should select the matching tool for different file types to avoid using the wrong function.
5. Why is it recommended to test before batch processing?
Batch renaming will affect multiple files at once. To ensure the naming results meet expectations, it's recommended to first select a few representative PDFs for testing, including files with clear barcodes, files with slightly different barcode positions, and files that might have multiple barcodes. After the test results are correct, perform batch processing on the complete folder.
Summary: Turning PDF Barcode Numbers into File Names to Improve Archiving Efficiency
When PDF file names are disconnected from the file content, subsequent organizing and searching become inefficient. Using the "Rename PDF Files Using File Content" function of HeSoft Doc Batch Tool , you can use the first barcode image in a PDF as the recognition source, batch-extract the barcode text, and use it as the file name. After processing, the original sequential files like 1.pdf, 2.pdf become files with corresponding barcode numbers, making file management clearer.
For users who frequently handle scanned PDFs, barcode documents, logistics data, inspection reports, and archive files, this batch automatic naming method can significantly reduce repetitive labor and lower manual input errors. It is recommended to delegate this type of rule-based file organization to batch processing tools in daily office work, leaving time for work that requires more judgment and review.
