IronPDF vs PDFSharpCore: ¿Qué Biblioteca de PDF .NET Debe Elegir en 2025?

¿Qué es IronPDF?

IronPDF es una biblioteca comercial integral de .NET diseñada para hacer que la generación, edición y manipulación de PDF sea sencilla para los desarrolladores. Construida sobre un motor de renderizado basado en Chrome, se destaca en la conversión de contenido HTML, CSS y JavaScript en PDFs perfectos. La biblioteca ofrece un conjunto de características extenso que incluye conversión de HTML a PDF, firmas digitales, marcado de agua, encriptación de PDFs y gestión de formularios.

IronPDF es compatible con versiones modernas de .NET, incluyendo .NET 10, 9, 8, 7, 6, 5, Core 3.1+ y Framework 4.6.2+, lo que lo hace versátil tanto para aplicaciones nuevas como heredadas. Su arquitectura optimizada para la nube asegura un despliegue sin problemas en entornos Azure, AWS y Docker.

¿Qué es PDFSharpCore?

PDFSharpCore es una biblioteca de código abierto que actúa como un puerto de .NET Core de la biblioteca original PDFsharp. Lanzada bajo la licencia MIT, se centra en la creación de PDFs programática y en la manipulación básica sin depender de bibliotecas específicas de Windows. Esto la convierte en una excelente opción para proyectos multiplataforma que se ejecutan en Linux, macOS y Windows.

Aunque PDFSharpCore no ofrece conversión de HTML a PDF de forma nativa, proporciona un control preciso sobre la creación de documentos PDF a través de su API de dibujo. Los desarrolladores pueden construir manualmente documentos PDF posicionando texto, imágenes y gráficos utilizando comandos de dibujo basados en coordenadas.

PDFSharpCore: Construcción manual de documentos

PDFSharpCore toma un enfoque fundamentalmente diferente, requiriendo que los desarrolladores construyan manualmente documentos PDF usando comandos de dibujo. Aunque esto proporciona un control preciso, requiere significativamente más código para diseños complejos.

using PdfSharpCore.Drawing;
using PdfSharpCore.Pdf;
using System;

        // Define fonts
        var titleFont = new XFont("Arial", 24, XFontStyle.Bold);
        var headingFont = new XFont("Arial", 14, XFontStyle.Bold);
        var normalFont = new XFont("Arial", 11, XFontStyle.Regular);

        var titleBrush = new XLinearGradientBrush(

Como puede ver, crear incluso un documento moderadamente complejo con PDFSharpCore requiere:

• Posicionamiento manual de cada elemento
• Cálculos complejos para los diseños
• Sin soporte integrado para HTML o CSS
• Implementación manual de gráficos y gráficos
• Código significativamente mayor para obtener el mismo resultado

HTML a PDF con PDFSharpCore

Dado que PDFSharpCore no admite nativamente la conversión de HTML a PDF, los desarrolladores deben usar bibliotecas de terceros. Una opción popular es combinar PDFSharpCore con HtmlRenderer:

using PdfSharpCore.Pdf;
using TheArtOfDev.HtmlRenderer.PdfSharp;

var document = new PdfDocument();
string htmlContent = File.ReadAllText("template.html");

// Note: HtmlRenderer has limited CSS support
PdfGenerator.AddPdfPages(document, htmlContent, PdfSharpCore.PageSize.A4);
document.Save("from-html.pdf");

using PdfSharpCore.Pdf;
using TheArtOfDev.HtmlRenderer.PdfSharp;

var document = new PdfDocument();
string htmlContent = File.ReadAllText("template.html");

// Note: HtmlRenderer has limited CSS support
PdfGenerator.AddPdfPages(document, htmlContent, PdfSharpCore.PageSize.A4);
document.Save("from-html.pdf");

Sin embargo, este enfoque tiene limitaciones significativas:

• Soporte limitado para CSS3 (aproximadamente 70-80% de compatibilidad)
• Sin ejecución de JavaScript
• Manejo deficiente de funciones web modernas
• Renderizado inconsistente en comparación con los navegadores

Salida: PDF de gestión de proyectos profesional con diseños basados en flexbox de Bootstrap 5, componentes de barra de progreso, utilidades de insignias, sistemas de tarjetas responsivas y componentes de alerta, todo renderizado con alineación, espaciado y precisión de color perfectos.

PDFSharpCore: Sin compatibilidad con HTML nativo

PDFSharpCore no tiene ningún motor de renderizado HTML nativo. La biblioteca está diseñada exclusivamente para manipulación de PDF a bajo nivel y operaciones de dibujo:

• Sin soporte de Bootstrap: no se pueden procesar marcos HTML/CSS en absoluto
• Sin flexbox ni CSS Grid: No hay ninguna capacidad de renderizado CSS
• Solo construcción manual: requiere dibujar texto, formas e imágenes mediante API basadas en coordenadas
• Se requieren herramientas externas: se deben utilizar renderizadores HTML o servicios de conversión de terceros

La integración de HtmlRenderer (tercero) solo proporciona soporte básico para HTML con limitaciones severas: aproximadamente 70-80% de compatibilidad con CSS3, sin flexbox, sin Grid CSS, y sin soporte para marcos modernos.

Impacto en el desarrollo: los equipos deben abandonar por completo los flujos de trabajo basados en HTML o integrar múltiples herramientas (PDFSharpCore + renderizador HTML externo), lo que agrega complejidad, carga de mantenimiento y posibles problemas de compatibilidad entre las versiones de la biblioteca.

Para obtener una compatibilidad detallada del marco Bootstrap y capacidades de renderizado CSS3, consulte la Guía de CSS Bootstrap & Flexbox.
