Create PDFs in C# —
Without the Free-Tool Tax

Design your document in HTML and CSS, render it with a Chromium engine, ship it in three lines of C#. No fluent-API layout code to hand-write, no AGPL obligations, no unmaintained WebKit forks. Works on .NET 10, 9, 8, Framework, Core, and Standard.

Create PDFs from HTML, CSS3, and JavaScript — not from 400 lines of layout code

One method call: RenderHtmlAsPdf(), RenderUrlAsPdf(), RenderHtmlFileAsPdf()

The free options each ask for something back. A fluent drawing API asks you to rebuild layout in C# and re-code it every time marketing moves a logo. A browser automation wrapper asks you to ship, patch, and memory-manage a Chromium binary in production. A copyleft licence asks you to open-source your application or negotiate a commercial deal anyway. An abandoned WebKit port asks you to explain to your team why flexbox does not render. IronPDF is a supported Chromium engine behind a clean .NET API, with a commercial licence and an engineer on the other end of the ticket.

Wo wir in der Vergangenheit ein Plug-in oder ein Paket für OCR verwenden mussten und ein anderes für PDFs, war es für uns wirklich großartig, alles in einem kostengünstigen Paket integriert zu haben.
