If a large number of PDF files are named only by serial numbers, subsequent search and archiving will be very troublesome. For PDFs with barcodes on the pages, you can use office software to identify the barcode numbers from the file contents and batch rename them as new PDF file names. This article focuses on common scenarios such as orders, archives, and reports, explaining how to use HeSoft Doc Batch Tool to rename PDFs by barcode numbers.
Many businesses accumulate a large number of PDFs in daily office work: order PDFs, logistics waybills, inspection reports, scanned contracts, archival materials, training materials, etc. These files often come from scanners, business systems, or bulk export programs, and after being saved locally, their filenames might just be temporary names like 1.pdf, 2.pdf, 3.pdf. The problem is that the filenames have no business meaning, so to find a specific order, a particular report, or a file corresponding to a certain number, you have to open and check each one individually.
If the PDF already contains a barcode, and that barcode corresponds to a unique string of numbers, then that string of numbers can be used directly as the filename. This way, the filename itself becomes an index, making subsequent searching, archiving, uploading to systems, or checking against Excel spreadsheets and database numbers much more convenient.
The approach introduced in this article is to use the PDF content renaming feature in the office software " HeSoft Doc Batch Tool " to batch extract the first barcode image from PDFs and rename the PDF files with the recognized barcode text. Compared to manually renaming files one by one, this batch processing method is more suitable for office scenarios with a large number of files and unified naming rules.
Applicable Scenarios
Batch renaming by PDF barcode number is suitable for the following workflows:
First, organizing order materials. Each order PDF page has a barcode or order number barcode, but after the file is exported, it's just a system serial number or sequence number. After renaming by barcode number, customer service, warehouse, and finance departments can quickly search by order number.
Second, archiving scanned documents. After paper archives are scanned into PDFs, the filenames are usually automatically generated by scanning software. If the archive pages have barcode labels attached, the barcode text can be used as the filename, reducing the workload of manually entering numbers.
Third, managing inspection reports and sample reports. Report PDFs often contain barcodes corresponding to sample numbers, report numbers, or experiment numbers. After batch renaming, files are easier to match with sample ledgers.
Fourth, managing logistics, warehousing, and asset files. Box numbers, cargo numbers, asset numbers, etc., often appear in PDFs as barcodes and are suitable for direct use as filenames, facilitating cross-departmental transfer and long-term preservation.
Effect Preview: From Sequential PDFs to Barcode Number PDFs
Let's first look at the file status before processing. There are 4 PDFs in the folder, with filenames 1.pdf, 2.pdf, 3.pdf, and 4.pdf respectively. These names only indicate order, unable to express the file content or indicate which barcode number each PDF corresponds to.

Now let's open the PDF to observe the content. In the screenshot, there is a barcode in the upper right corner of the PDF page, with the number 20036655 displayed below the barcode. The red arrow points to the exact barcode text to be extracted. As long as each PDF has a similar barcode number, it can be used as the basis for file renaming.

After processing, the filenames are no longer simple sequential numbers, but have become 10026877.pdf, 20036655.pdf, 20100511.pdf, and 33952100.pdf. The filenames are consistent with the barcode numbers inside the PDFs. For subsequent searching, you can directly search for the number in the folder.

Operation Steps
Step 1: Find "Rename PDF files using file content" on the tool's homepage
After opening HeSoft Doc Batch Tool , first enter the "File Name" category from the left menu. This category centrally provides batch processing capabilities related to filenames, such as batch replacing filename keywords, inserting text into filenames, adding prefixes and suffixes, adding parent folder names, adding page counts, etc.
For this task, you need to select the 7th item, "Rename PDF files using file content". The description on this function card in the screenshot is "Batch use certain text from the PDF file content as the filename for that file." This indicates that it does not simply modify existing filenames, but extracts content from inside the PDF and uses it for renaming.

The expected result of this step is to enter the dedicated workflow page for renaming using PDF content. Since we are processing PDF files, do not select other functions like Word content renaming or text file content renaming.
Step 2: Import the PDF files to be renamed
After entering the function page, the interface displays four workflow nodes: Select records to process, Set processing options, Set save location, and Start processing. First, you need to import the files to be processed in step 1.
The top button area provides "Add Files" and "Import Files from Folder". If you only need to process a few specific PDFs, you can use "Add Files"; if a folder contains all the PDFs to be processed, you can batch add them via "Import Files from Folder". After importing, the files will be displayed in the table.

In the screenshot, 4 records have been imported, all with the file extension pdf, and the paths point to 1.pdf, 2.pdf, 3.pdf, 4.pdf in the D:\test directory. The summary at the bottom shows the record count as 4. After confirming the list is correct, click "Next" at the bottom of the page.
The purpose of this step is to establish a batch task list. Only PDFs appearing in the list will participate in the subsequent barcode recognition and renaming.
Step 3: Choose to extract the name from "First barcode image"
After reaching step 2, "Set processing options", you need to configure the extraction rules. The "Search Area" in the interface contains three options: First line of text, First barcode image, Text matched by custom formula.
In this example, the target content on the PDF page is a barcode, so select "First barcode image". This means the software will recognize and extract the corresponding text based on barcode image recognition logic, rather than reading it as a regular text line.

Then, in the "Position" area, select how to write the filename. In the screenshot, "Overwrite the entire filename" is selected. This is very suitable for completely replacing the original filename with the barcode number. For example, if the original filename is 2.pdf and the barcode text recognized within the PDF is 20036655, after processing it will become 20036655.pdf.
If actual business needs require keeping the original sequence number, you can also consider placing it to the left or right of the filename based on the interface options. However, for order and archive filing, it is generally recommended to use "Overwrite the entire filename" to keep the filename concise and easy for searching and system identification.
Step 4: Continue setting the save location and execute batch processing
After completing the extraction rules and naming position settings, continue following the interface workflow to step 3, "Set save location". Batch renaming involves multiple files, and it is recommended to choose a safe saving method based on file importance. For formal materials, it is recommended to output to a new folder first, and after confirming that barcode recognition and filenames are correct, then replace or archive the original files.
Next, proceed to step 4, "Start processing". The software will, based on the imported file list, read the first barcode image from each PDF content one by one and write the recognized text into the filename. Wait for the task to complete, and then check the results at the save location.
The expected result of this step is for the folder to contain PDFs named by barcode number. The file extension remains .pdf, while the main part of the filename has changed from the original sequential number to the corresponding barcode digits.
Common Issues and Notes
1. Must the barcode numbers in the PDF be clear?
Clarity is recommended. Barcode recognition depends on image quality. If the PDF is a low-resolution scan, or if the barcode is compressed, distorted, or obscured, it may affect the recognition results. Before formal batch processing, it is best to randomly spot-check a few PDFs for testing.
2. What if there are multiple barcodes in each PDF?
The option in the screenshot is "First barcode image," so this is more suitable for situations where each PDF has only one primary barcode, or where the target barcode is the first one in the recognition order. If there are multiple barcodes in a PDF, you need to first confirm that the software extracts the barcode that is needed for the filename in your business process.
3. Is there a one-to-one correspondence between barcode text and filename?
Ideally, the barcode number in each PDF should be unique. If multiple PDFs recognize the same number, it may cause issues with duplicate filenames. It is recommended to confirm the barcode numbering rules before processing and spot-check the number of files and filenames after processing to see if they meet expectations.
4. Can this be used for doc, docx, or Word files?
This article covers PDF files. In the screenshot, other functions like "Rename Word files using file content" can also be seen on the same tool page, but the workflow chosen for this task is "Rename PDF files using file content". To process Word documents like .doc or .docx, you should enter the corresponding Word function, not the PDF renaming workflow.
5. Do PDF readers need to be closed before processing?
If some PDFs are currently open in a reader or other program, it may affect file reading and writing. It is recommended to close the relevant PDFs that are open before batch processing to prevent file access conflicts that could cause task failure or inability to save.
Summary
When PDF filenames are just sequence numbers like 1.pdf, 2.pdf, file management efficiency is very low; however, when PDFs already contain barcode numbers internally, the most reasonable approach is to extract the barcode text and batch use it as the PDF filename. This transforms the filename from "unreadable" into a business number that is "searchable, verifiable, and archivable".
HeSoft Doc Batch Tool , as a batch file processing software designed for office scenarios, can help users reduce the steps of repeatedly opening PDFs, checking barcodes, and manually renaming files. By following the workflow in this article—entering the "File Name" category, selecting "Rename PDF files using file content", importing PDFs, setting the search area to "First barcode image", and using the recognition result to overwrite the entire filename—you can quickly complete batch renaming of PDFs by barcode number. It is recommended to test with a small number of files first before batch processing formal materials to achieve more stable sorting results.
