No native renderer
Pure C# output with no Chromium, wkhtmltopdf, or runtime deployment surprises.
Free, MIT-licensed PDF generation for .NET
Create clean PDFs directly from C#.
TerraPDF is a lightweight, zero-dependency PDF library for invoices, reports, tables, QR codes, barcodes, bookmarks, custom fonts, and encrypted documents.
Zero dependencies
Pure C#

v2.0.1
New release
TerraPDF 2.0.1 fixes table spans and pagination.
Column spans, row spans, header-less tables, and tables placed directly in page content now paginate more predictably.
From C# code to a finished PDF
Write the document in a fluent API. TerraPDF lays it out, paginates it, and writes the file.
