ZBar is an open-source C library and software suite for reading bar codes from video streams, image files, and raw intensity sensors. It supports symbologies like EAN/UPC, Code 128, Code 39, Interleaved 2 of 5, and QR Code, with CLI tools, GUI widgets, and bindings for Python, Perl, and C++.

Use cases

  • decode qr codes from images
  • scan barcodes from a webcam video stream
  • read upc codes from product photos in a script
  • embed barcode scanning in an embedded c application
  • add a barcode scanning widget to a qt or gtk app
  • batch decode barcodes from image files via command line

When to choose

  • you need a lightweight, fast C barcode decoder with a small memory footprint
  • you want bindings for Python, Perl, or C++ or GUI widgets for Qt/GTK
  • you target embedded or low-resource platforms without floating point requirements
  • you need support for common 1D symbologies plus QR codes

When to avoid

  • you need modern actively developed features or new symbologies
  • you want a pure high-level language solution without C dependencies
  • you need robust scanning of damaged or low-quality images with modern ML-based decoders
