Enterprise PDF for Go

The enterprise PDF library
Go doesn't have.

Generate archival PDF/A, sign documents with PAdES, encrypt with AES-256 and produce accessible PDF/UA from idiomatic Go. One memory-safe core, the same behavior as every other binding, running entirely on your servers: no per-document SaaS fees, no data leaving your network, no AGPL strings.

Add the module. A prebuilt static library ships inside it, nothing to compile.

Why Go teams pick rust-pdf

Go powers the services that emit invoices, statements and e-invoices at scale, but its PDF story stops at drawing boxes and text. PDF/A archival, qualified signatures, AES-256 and PDF/UA simply aren't there, so teams shell out to headless Chrome or pay a per-document SaaS that uploads their documents.

rust-pdf is one go get with a prebuilt static libpdf_ffi.a bundled in the module (cgo, nothing to compile), an idiomatic Document / EditableDoc API, and a single offline license that unlocks the corporate features.

Native, not headless Chrome: no browser process, no gigabytes of RAM per worker.
Runs on your servers: documents never leave your network and nothing phones home, ideal for LGPD/GDPR, fintech and health.
No AGPL trap: a commercial per-application license, never the AGPL of iText or the per-server billing of Aspose.
Deterministic output: the same input always produces the same bytes, so you can diff and audit it.
Free to build with: everyday PDF generation is free forever; you only license the regulated-grade features.

Free to build with. Licensed when you ship.

Prototype and generate everyday PDFs for free. When you need archival, signatures, encryption or accessibility, one license unlocks them all in Go and every other binding.

Author a tagged PDF/A in a few lines of Go

// go get github.com/rustpdf/rustpdf-go@latest
import rustpdf "github.com/rustpdf/rustpdf-go"

doc, _ := rustpdf.New()
defer doc.Close()
doc.PdfaLevel(rustpdf.A2a)
doc.Tagged()
doc.SetInfo(rustpdf.Info{Title: "Q3 Report"})
f, _ := doc.AddFontFile("Roboto-Regular.ttf")
doc.AddPage()
doc.ShowText(f, 26, 72, 760, "Annual report", 1) // heading level 1 = H1
data, _ := doc.ToBytes()                          // archival-grade, accessible PDF

The full Go reference (fonts, images, forms, manipulation, encryption and signatures) lives in the Go docs.
