Read Barcodes and QR Code from Images - PDF, Tiff, JPEG and more

Efficiently embed high-speed and reliable barcode reading functionality in your web, desktop or mobile application using just a few lines of code to meet your business needs.

Powerful Barcode Decoding

  • Multi-thread barcode processing
  • Reads multiple barcodes in one image
  • Detects barcodes at any orientation and rotation angle
  • Decodes barcodes from out-of-focus, blurred images
  • Reads barcodes from low-quality images with preprocessing

Customization and Flexibility

Though our SDK performs well in many general scenarios with its default scanning settings, but to reach its best performance for your specific business need, our SDK is fully customizable for the greatest performance just for your business.
Choose between a long list of parameters, each containing a set of modes. A mode is a special function that the barcode reader can do, and each mode can include a number of arguments, which are used to further refine or customize the application.
