SelectPdf makes HTML to PDF and PDF tools for .NET developers, since 2014. SelectPdf.Universal is our new flagship .NET PDF library: it runs on Windows, Linux (x64 and ARM64) and macOS on Apple Silicon, on .NET 8 and .NET 10, and in Docker with nothing to apt-get. It converts HTML to PDF with the latest Chromium engine, converts Word documents to PDF, and creates, edits, merges, signs and redacts PDF files, including PDF/A-4, PDF/UA-2 and ZUGFeRD / Factur-X output. The classic SelectPdf library continues on Windows, from .NET Framework 2.0 to .NET 10. One perpetual license covers both, and the free Community Edition converts HTML to PDF up to 5 pages per document. For other languages, the SelectPdf Online API does the same conversion over REST. SelectPdf libraries have been downloaded more than 23 million times from NuGet. https://selectpdf.com
