Rivoli PDF / .NET PDF library
The .NET PDF library that's actually just .NET
One managed NuGet package that builds, reads, and round-trips PDFs on .NET 8 and .NET 10. No Ghostscript, no Chromium, no platform-specific binaries: the same bytes on your laptop, your CI, and your Linux containers.
Install and generate
No system libraries, no headless browser, no per-platform setup. Rivoli.Pdf 0.1.0 targets .NET 8 and .NET 10.
using Rivoli.Pdf;
using Rivoli.Pdf.Builders;
var doc = Document.Create("Quarterly Report", "Acme Corp");
doc.AddSection()
.H1("Quarterly Report")
.AddParagraph("Revenue grew 18% over the prior quarter.")
.AddTable(t => t
.Header("Quarter", "Revenue")
.Row("Q1", "$1.2M")
.Row("Q2", "$1.5M"));
doc.SavePdf("report.pdf");That's a complete program. The document model handles sections, headings, tables, lists, images, headers and footers, and cascading styles; the renderer adds encryption, signatures, and PDF/A.
The output
Real output from the runnable samples in the Rivoli PDF repository.

Competitor prices are researched approximations (June 2026); several vendors are now quote-gated, so some figures are historical or third-party. Rivoli PDF is pre-1.0: document creation is feature-complete, while full parsing of arbitrary PDFs and rasterized rendering are partial and on the near-term roadmap.

Adopting Rivoli PDF
Coming from any .NET PDF library, the mental shift is the same: describe structure, stop placing coordinates.
- 01 Add the package: dotnet add package Rivoli.Pdf (the document model ships in Rivoli.Pdf.Core, pulled in automatically).
- 02 Describe documents as a tree of sections, paragraphs, and tables instead of pages and coordinates; the layout engine places content for A4 or Letter without changes.
- 03 Move save-time concerns (encryption, PDF/A, tagging) to PdfSaveOptions on PdfDocumentRenderer.
- 04 Add a determinism check to CI: render twice, compare hashes. It catches template regressions for free.
- 05 Before migrating reading-heavy workflows (filling existing forms, rendering pages to images), check current support in the docs gallery: Rivoli PDF is pre-1.0 and strongest at authoring.
The full migration guide, with concept mappings and before/after code, lives in the documentation.
