Iron Barcode is a C# .NET software library allowing software developers to read and write QR codes and barcodes in .NET Framework applications and websites. It is available from https://ironsoftware.com/csharp/barcode. It is also available on NuGet using the package name Barcode https://www.nuget.org/packages/barcode.

Iron Barcode features full online documentation, software tutorials, a NuGet installer, GitHub Repositories with examples, and technical support provided by the original development team. Iron Barcode is available for .NET Framework 4.0 and higher with Microsoft Azure support.

Iron Barcode allows developers of .NET applications to scan and generate barcodes in many formats. These include the two-dimensional matrix formats such as QR codes, Aztec, and Beta Matrix. QR codes can be styled, colored, and even have logos added. In addition, Iron Barcode can read MaxiCode UPS barcodes and USPS mail barcodes. Modern linear formats that are supported include Code 93, Code 128, and PDF417. These barcode formats allow almost any type of data, including strings and binary data, to be encoded into linear barcodes. Iron Barcode also supports traditional numeric barcodes, including UPC-A, UPC-E, EAN-8, EAN-13, ITF, Codabar, MSI, and Plessey.

Barcodes can be read from System.Drawing.Bitmap and System.Drawing.Image.Objects in addition to file formats, including JPEG images, PNGs, Bitmaps, TIFFs, GIFs, and PDF documents.

Iron Barcode provides barcode and QR code writing functionality with fault awareness and tolerance and a fluent style API allowing barcode images to be styled, resized, and annotated in a single line of code. The resulting barcodes can be exported as native .NET objects or saved as image files, saved as PDFs, or added to existing PDFs. Iron Barcode also allows barcode images to be encoded as HTML.

Coming soon, we also have support for .NET Core 2.0 and above and Xamarin, with free upgrades provided to existing customers.
