Making barcodes one at a time is fine for one label — but if you have a product catalog or an inventory list, you need them in bulk. With a CSV upload you can generate hundreds of Code 128 barcodes at once and download them all as a ZIP of PNG images, free and in your browser.
Open Barcode GeneratorHow Bulk Barcode Generation Works
- 1Open the WowShortcuts Barcode Generator and switch to Bulk mode.
- 2Upload your CSV (or paste a list of values), then pick which column holds the barcode codes.
- 3Adjust the bar width, height, and label, then click Download ZIP — you get one PNG per row.
Your CSV can have any columns — you just tell the tool which one is the barcode value (e.g. the SKU column).
Preparing Your CSV
A simple CSV with a header row works perfectly:
- First row: column names like SKU, Product Name, Price
- Each following row: one item
- Pick the SKU (or code) column as the barcode value
- Optionally pick another column to name the image files
What Is Code 128?
Code 128 is the most widely used 1D barcode for shipping, inventory, products, and asset tags. It encodes letters, numbers, and symbols, includes a checksum, and is read by any standard scanner or phone app.
Common Uses
- Product labels for a store or warehouse
- Asset tags for equipment tracking
- Inventory and stock management
- Shipping and packing labels
