Why Use Our Online Barcode Tool?

In Warehouse Management and POS systems, Barcodes are essential for speed and accuracy. We developed the ITKB Barcode Toolbox to solve common pain points such as expensive software, complicated bulk generation, and non-standard formats that scanners cannot read.

Advantages

  • Code 128 Standard: Globally recognized and readable by all scanner brands.
  • Bulk Export: Upload Excel data and receive generated barcodes formatted in a table.
  • Privacy First: 100% browser-based processing. Your product data is never sent to our servers.
  • Free to Use: Completely free with no usage limits.

Limitations

  • English Only: Thai language is not supported due to CODE 128 standard constraints.
  • Character Limit: Keep it under 20-30 characters for easy scanning.
  • Density: Longer data makes the barcode dense and harder to scan on small labels.

How to Use

1. Single Generation: Enter a product ID or English text into the input field. The system generates the barcode in real-time. Review it and click "Download Image".

2. Camera Scanner: Switch to the "Scan" tab and open your camera. Align the red laser with your barcode, and the system will decode it instantly.

3. Image Scanner: Upload an image file (.jpg, .png) containing a barcode to extract its data.

4. Bulk Generation: Prepare an Excel file with your data in Column A. Upload via "Generate from Excel," and the system will provide a ready-to-use file with barcode images.
