How to Use a Bulk Barcode Generator for CODE 128 PDFs

Creating hundreds of unique CODE 128 barcodes for inventory or shipping labels can be a tedious task. Doing it one by one is slow and invites errors. Our free Bulk Barcode Generator is the perfect solution, allowing you to create a print-ready, multi-page PDF from your data in seconds.

Why Generate CODE 128 to PDF?

CODE 128 is a highly efficient, high-density barcode format that can encode alphanumeric characters, making it ideal for logistics and internal tracking. Exporting directly to a multi-page PDF ensures that every label is perfectly formatted for printing, saving you time and effort.

Step 1: Prepare Your Data File

Your data should be in a CSV or Excel (`.xlsx`) file. The first row must be your headers (e.g., `SKU`, `ItemID`). Every subsequent row will become a unique barcode in your final PDF.

Step 2: Configure Your CODE 128 Label

Navigate to the Bulk Barcode Generator and upload your file.

1. Set Label Size: Define the dimensions for your labels (e.g., 100mm x 50mm).
2. Add a Barcode: Click "Add Barcode" in the configurator.
3. Select Format: In the properties for the barcode element, choose CODE128 from the format dropdown.
4. Link Data: Use the "Link to Data Column" dropdown to connect the barcode's value to your spreadsheet header (e.g., `SKU`).

You will see a live preview of the label, populated with data from the first row of your file. You can also add text elements and link them to other data columns.

Step 3: Generate Your Multi-Page PDF

Once you are happy with the design, click the "Generate & Download" button.

• In the download dialog, select PDF as the format.
