Download PDFjet Core for .NET 9.1.1

PDFjet Core has everything you need to put PDFjet to work in your own projects:

• PDFjet.dll, the complete library
• The API reference
• 50 ready-to-run examples, with the PDFs they create
• Fonts for the world's languages, ready to embed

Requires .NET 8 or later, or .NET Framework 4.8. The download is about 290 MB, mostly fonts. Unzip it and run build-dotnet.sh or build-dotnet.cmd to build and run all the examples. The license is in the download.

Or add it from NuGet

PDFjet Core is on NuGet as PDFjet: the library alone, PDFjet.dll for .NET 8 or later and for .NET Framework 4.8, strong-named. With the .NET CLI:

dotnet add package PDFjet --version 9.1.1

Or in the project file:

<PackageReference Include="PDFjet"
                  Version="9.1.1" />

The package has no fonts: take the ones you use from the download above, or from pdfjet-fonts. The core fonts, such as Helvetica, need no files.

Need digital signatures or electronic invoices? PDFjet Pro adds them: see the Solo and Team licenses, from $295 US.

What our clients are saying:

"I find PDFjet simpler to use than a lot of other components that are available. The fact that PDFjet allows writing PDFs to a stream (some others don't) is a bonus. PDFjet is easy to use and it is inexpensive. Best of all support is fantastic."

Simon Nitz

Senior Technical Consultant

"I tried to use three other open source PDF libraries, but their source code is not well documented and so "object-oriented" it's proven nearly impossible to read and modify. In contrast I found the PDFjet source code very simple, clean, logical and easy to understand. The fact that it came with very liberal open source license is a huge bonus. The commercial version is very reasonably priced and there are NO ROYALTIES. I wish I had discovered this excellent product earlier."
