When each PDF file contains unique barcodes such as product numbers, order numbers, or tracking numbers, but the file names do not match the barcodes inside, searching for and managing these files can cause us to spend more unnecessary time verifying them. Especially in e-commerce or logistics industries, scenarios where barcodes exist in PDFs are particularly common. In such cases, we typically open the PDF, check the barcode, copy its code, close the file, and then paste the code onto the file to rename it. The low efficiency of this manual operation is secondary; the main issue is that when there are many files, it is very easy to make pasting errors.
So how can I skip these tedious and repetitive steps and directly batch-rename files based on the barcodes in PDF documents? Today, I’ll teach you three of the most convenient and straightforward methods. Whether you use a local tool for assisted operations or process with an online tool, you’ll learn quickly and can apply it right after reading.
When should you change a PDF's file name to the barcode number found inside the file?
Updating File Names
In daily work, changing a PDF file name to a barcode number that appears in the document is usually done to make files easy to identify and manage. Many companies process a large volume of documents every day. If file names are not organized, it is difficult to quickly find the corresponding content. For example, with logistics tracking numbers, product SKUs, or order numbers, using a barcode as the file name is like attaching a unique ID to each document. No matter where you are, you can quickly look it up without confusing it with other files.
Facilitating System Recognition
When importing files, the system will automatically match the file name with the corresponding record in the database. If the file name is not the barcode number, the system may fail to recognize it correctly, leading to problems like import recognition issues, content mismatches, and data errors. Therefore, we must change the PDF file name to the barcode number in the file to allow the system to read it smoothly. It’s just like writing the correct express tracking number so the courier company knows who the package belongs to.
Avoiding Manual Errors
When handling files manually, if the barcode and name are inconsistent, subsequent processes can lead to difficulties in searching, duplicate processing, or even missed files. This risk increases significantly when dealing with a large number of files. Therefore, changing the PDF file name to the barcode makes the file completely consistent with its content, allowing all operators to identify it at a glance and avoid manual verification. This not only reduces workload but also lowers the chance of human error.
Preview of the effect of renaming files based on barcodes in PDFs
Before processing:
After processing:
Method 1: Use HeSoft Doc Batch Tool to rename PDFs to the barcode number in the document
Recommendation Index: ★★★★★
Advantages:
- The functionality is relatively complete, with simple and easy-to-understand operations. It supports batch processing of multiple files and comes with technical support, allowing even beginners to operate quickly.
- All file processing is done locally without the need to upload files, protecting user privacy.
Disadvantages:
- Requires installing software on a computer to operate.
Steps:
1. Open [ HeSoft Doc Batch Tool ], select [File Name] - [Rename PDF Files Using File Content].
2. In [Add Files] or [Import files from folder], choose a method to add the PDF files you want to rename. You can also drag files and drop them below for import. After confirming the files are correct, click Next.
3. Enter the settings options interface. In the search area, select [First barcode image]. In the position area, select [Overwrite entire file name]. If you need to keep the original file name, you can add the barcode number to the left or right of the file name. Finally, click Next, then click Browse to choose the save location for the new files.
4. After waiting for the process to finish, click the red path to open the folder. You can then see that all PDFs have been successfully renamed to the barcode number from within the document.
Method 2: Use an online tool to recognize barcodes and rename PDF files
Recommendation Index: ★★★☆☆
Advantages:
- No software installation needed, and it is free to use.
- Can be operated anytime, anywhere, and can also be processed on mobile devices.
Disadvantages:
- Cannot batch-process multiple files; requires manual copy-and-paste.
- Uploading files may carry a risk of privacy leakage.
Steps:
1. Open the [Online Barcode Reader] website and upload the PDF file.
2. Wait for the barcode number to be automatically recognized, then copy the result.
3. Then manually rename the file.
Method 3: Use a Python script to automatically change PDF names to the barcode in the document
Recommendation Index: ★★☆☆☆
Advantages:
- Fully automated batch processing, completely free.
- Can be customized for various needs.
Disadvantages:
- Requires a foundation in Python programming, which has a higher learning curve.
- Python environment configuration is relatively complex.
Steps:
1. Install Python and the Pyzbar library.
2. Create a new script named barcode_rename.py:
import os
from pyzbar.pyzbar import decode
from PIL import Image
import fitz # PyMuPDF
for pdf_file in os.listdir('.'):
if pdf_file.endswith('.pdf'):
# Extract barcode
doc = fitz.open(pdf_file)
page = doc[0]
pix = page.get_pixmap()
image = Image.frombytes("RGB", [pix.width, pix.height], pix.samples)
# Recognize barcode
barcodes = decode(image)
if barcodes:
new_name = barcodes[0].data.decode() + '.pdf'
os.rename(pdf_file, new_name)
3. Finally, run the script to automatically rename.
