ZXing.PngWriter

An extremely fast barcode generator binding for ZXing.Net

Built for .NET 8+ this library takes advantage of Span<T>, Vector<T> SIMD, and ArrayPool<T> to produce png Streams with minimal overhead.

A QR code for https://example.com is just 417 bytes.

NuGet

Usage

var writer = new PngWriter
{
    Format = BarcodeFormat.QR_CODE
};

using var stream = writer.Write("https://example.com");

With PNG metadata:

var writer = new PngWriter
{
    Format = BarcodeFormat.QR_CODE
};

var textInfo = new TextualInformation
{
    Software = "My App",
    Comment = "Generated QR code"
};

using var stream = writer.Write("https://example.com", textInfo);

Performance

Generates up to ~8,000 QR codes per second on a single thread (120–580 μs depending on content size).

Recent optimizations (cross-platform SIMD, removal of reflection, built-in compression and hashing) improved throughput by 10–66% and reduced allocations by 6–57% compared to v0.3.
