2D Barcodes
Beyond the QR Code
A QR code is the most recognizable 2D barcode, but it isn't the only one. Depending on the industry, you'll run into a handful of other square and rectangular formats that solve slightly different problems — packing more data into a tiny space, staying readable without a blank border, or fitting a government ID's worth of information into a single code. Looking for QR codes specifically? See the QR Codes collection instead.
PDF417
The PDF417 Barcode Generator creates a rectangular, stacked barcode built to hold large amounts of text — the same format printed on the back of many U.S. driver's licenses, government forms, and shipping and inventory labels.
Data Matrix
The Data Matrix Generator creates a compact square barcode designed to stay readable even at a tiny printed size, which is why it's the standard choice for marking small electronics, medical devices, and individual parts directly.
Aztec Code
The Aztec Code Generator creates a square barcode that — unlike most other formats — doesn't need a blank quiet zone around it to scan reliably, making it a common pick for tickets and boarding passes printed edge-to-edge on thermal paper.
2D Barcode Reader
Already have a 2D barcode and just need to know what it says? The 2D Barcode Reader decodes PDF417, Data Matrix, Aztec Code, QR codes, and common 1D barcodes from an uploaded or pasted image.
Batch Barcode Generator
Need many barcodes at once? The Batch Barcode Generator turns a pasted list into a full set of barcodes, downloadable together as a single ZIP file. It covers every format on this site — 2D formats here plus QR codes and the 1D formats like Code 128 and UPC/EAN.
