**TL;DR**

Choose a C# PDF library around the work your application needs: generating documents, editing existing PDFs, converting HTML, or processing scans. Compare [Nutrient.NET SDK](https://www.nutrient.io/sdk/dotnet/), QuestPDF, iText Core, IronPDF, Syncfusion PDF, Aspose.PDF, and PDFsharp against your documents and deployment environment. For PDF/UA, check the supported conformance version and validation workflow separately from basic PDF generation.

Nutrient publishes this comparison and offers one of the SDKs listed. This is a feature-selection guide, not a measured performance ranking.

## What to look for in a C# PDF library

C# applications commonly require PDF processing for invoicing systems, document management platforms, and report generation. Maintaining a custom PDF generator also means maintaining its layout, font, and file-format handling.

Production requirements:

- **Features that work** — Reliable in production, not just marketing claims

- **Performance under load** — Reliable processing in high-concurrency scenarios

- **Licensing** — Check the terms for your deployment and usage.

- **Documentation quality** — Critical for implementation speed

- **Cross-platform support** — Development machines and modern.NET (8 and 10) on Linux containers

### How to evaluate PDF/UA support in C#

PDF/UA support isn’t a single yes/no feature. Separate three requirements: creating tagged documents, converting existing files, and validating the result. Ask which PDF/UA version the library supports and whether that support applies to your input format and chosen API.

For Nutrient, start with the [.NET PDF/UA overview](https://www.nutrient.io/guides/dotnet/pdfua.md). Then follow the guides for [PDF-to-PDF/UA conversion](https://www.nutrient.io/guides/dotnet/conversion/pdf-to-pdf-ua.md) and [PDF/UA-1 validation](https://www.nutrient.io/guides/dotnet/pdfua/validate-pdf-ua.md). These are implementation resources for C# developers; the broader [PDF accessibility solution](https://www.nutrient.io/solutions/pdf-accessibility/) describes the product options.

Test document language, reading order, headings, tables, and alternative text with representative files. Automated validation helps identify structural problems, but a successful conversion alone doesn’t establish that the document communicates its content accessibly.

### Check deployment and licensing before choosing

Confirm operating system,.NET version, native dependencies, licensed components, and deployment terms for the exact package you plan to ship. For Nutrient, consult the [system requirements](https://www.nutrient.io/guides/dotnet/about/system-compatibility.md). Benchmark your own page counts, concurrency, and memory use rather than treating feature breadth as a performance result.

## Library breakdown: Seven C# PDF libraries

Here’s a closer look at the leading C# PDF libraries in 2026, including their key strengths, limitations, and best-fit scenarios.

### 1. Nutrient.NET SDK (formerly GdPicture.NET)

- **Compliance** — PDF/A (including A-4), PDF/UA, digital signatures (certificates, timestamps, SHA-256)

- **Document operations and conversion** — Merge, split, and overlay; convert to/from PDF/PDF-A/images with optimization

- **Barcode, capture, print** — [1D and 2D barcodes](https://www.nutrient.io/sdk/solutions/scanning-barcodes/); TWAIN and WIA scanning; server and client printing

- **Deployment** — Check the [system requirements](https://www.nutrient.io/guides/dotnet/about/system-compatibility.md) for supported.NET versions, operating systems, and Windows-only features.

**Limitations:**

- The library’s broad range of capabilities can be excessive for projects that only require simple PDF generation.

**Best for:** Enterprise document workflows, AI-driven data extraction, multiformat processing pipelines, and applications that require strict compliance.

### Nutrient.NET SDK: OCR PDF in C#

This example adds searchable text to an unencrypted scanned PDF. Follow the [Nutrient.NET SDK setup guide](https://www.nutrient.io/sdk/dotnet/getting-started.md) for your platform’s native dependencies and a trial or commercial license that includes OCR. Create a.NET 8 console project and install the package used for this example:

```bash

dotnet new console --framework net8.0 --name PdfOcrDemo
cd PdfOcrDemo
dotnet add package GdPicture.API --version 14.4.9

```

Set `NUTRIENT_LICENSE_KEY` in your environment. Locate the OCR dictionary directory containing `eng.traineddata`, as described in the [OCR API reference](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPicturePDF~OcrPage.html). Replace `Program.cs` with the following code:

```csharp

using System;
using System.IO;
using GdPicture14;

try
{
    if (args.Length!= 3)
        throw new ArgumentException("Usage: dotnet run -- <input.pdf> <output.pdf> <OCR-dictionary-directory>");

    var input = Path.GetFullPath(args[0]);
    var output = Path.GetFullPath(args[1]);
    var dictionaries = Path.GetFullPath(args[2]);

    if (!File.Exists(input))
        throw new FileNotFoundException("Input PDF not found.", input);
    if (string.Equals(input, output, StringComparison.OrdinalIgnoreCase))
        throw new ArgumentException("Use a different path for the output PDF.");
    if (!File.Exists(Path.Combine(dictionaries, "eng.traineddata")))
        throw new FileNotFoundException("The OCR dictionary directory must contain eng.traineddata.");

    var key = Environment.GetEnvironmentVariable("NUTRIENT_LICENSE_KEY");
    if (string.IsNullOrWhiteSpace(key))
        throw new InvalidOperationException("Set NUTRIENT_LICENSE_KEY in your environment.");
    if (!new LicenseManager().RegisterKEY(key))
        throw new InvalidOperationException("The SDK license key could not be registered.");

    using var pdf = new GdPicturePDF();
    Check(pdf.LoadFromFile(input), "Load PDF");
    var pageCount = pdf.GetPageCount();
    Check(pdf.GetStat(), "Read page count");
    if (pageCount == 0)
        throw new InvalidOperationException("The input PDF has no pages.");

    for (var page = 1; page <= pageCount; page++)
    {
        Check(pdf.SelectPage(page), $"Select page {page}");
        Check(pdf.OcrPage("eng", dictionaries, "", 300), $"OCR page {page}");
    }

    Check(pdf.SaveToFile(output), "Save PDF");
    Console.WriteLine($"Created {output}");
    return 0;
}
catch (Exception error)
{
    Console.Error.WriteLine(error.Message);
    return 1;
}

static void Check(GdPictureStatus status, string operation)
{
    if (status!= GdPictureStatus.OK)
        throw new InvalidOperationException($"{operation} failed: {status}");
}

```

Run the program with your input PDF, a separate output path, and the dictionary directory. Replace the example dictionary path with your installation’s path:

```bash

dotnet run -- "source.pdf" "output.pdf" "/path/to/OCR"

```

The program stops and reports the operation if loading, page selection, OCR, or saving fails. The `using` declaration disposes of the PDF object even on failure. Open the output PDF and check its searchable text against the scan before using it downstream.

## Feature comparison of C# PDF libraries

Use the decision matrix above to build a shortlist. Then verify the exact operation in each vendor’s current documentation.

### Evaluate advanced capabilities separately

For OCR, structured extraction, PDF/A, PDF/UA, and document comparison, check the specific API and licensed component rather than relying on a general feature checkmark. PDF/A describes archival conformance; PDF/UA concerns accessibility. Neither is a substitute for the other.

Use the [Nutrient file-format list](https://www.nutrient.io/guides/dotnet/about/file-type-support.md) to confirm supported inputs and outputs. For HTML conversion specifically, read the [C# HTML-to-PDF method guide](https://www.nutrient.io/blog/how-to-convert-html-to-pdf-using-wkhtmltopdf-and-csharp.md) and compare how each renderer handles your CSS, fonts, and page breaks.
