MiniPdf
Lightweight Office-to-PDF libraries and command-line tools for .NET and Rust.
MiniPdf converts Office documents directly to PDF without Microsoft Office, LibreOffice, Adobe Acrobat, or COM automation at runtime. Choose the implementation that matches your project.
Choose an implementation
| .NET | Rust | |
|---|---|---|
| Status | Stable, full implementation | Experimental, under active development |
| Inputs | XLSX, DOCX, PPTX, PDF merge | XLSX, DOCX |
| Interfaces | .NET library, CLI, standalone Native AOT binaries | Rust crate, CLI |
| Content extraction | Markdown, JSON, semantic .NET model | Not yet available |
| Documentation | Open the .NET guide | Open the Rust guide |
For production use and the broadest document support, start with .NET. Choose Rust when you want a native Rust dependency and can work within its current conversion scope.
Quick start
.NET
dotnet add package MiniPdf
using MiniSoftware;
MiniPdf.ConvertToPdf("report.docx", "report.pdf");
Prefer a command-line tool?
dotnet tool install --global MiniPdf.Cli
minipdf report.docx -o report.pdf
The .NET guide covers conversion, content extraction, PDF merge, custom fonts, CLI options, and deployment.
Rust
cargo add minipdf
cargo install minipdf-cli
minipdf::convert_to_pdf("report.docx", "report.pdf")?;
minipdf report.docx -o report.pdf
The Rust guide documents the crate API, CLI, supported features, known gaps, and development workflow.
Why MiniPdf
- No office suite required: conversion runs inside your application or CLI.
- Small deployment surface: minimal dependencies and no external process.
- Server and CI friendly: works in containers, cloud services, and pipelines.
- Native command-line options: .NET Native AOT releases and a Rust CLI.
- Open development: Apache 2.0 licensed with reproducible visual benchmarks.
MiniPdf targets practical document conversion, not complete Microsoft Office layout compatibility. Complex templates may render differently; use the online demo or benchmark reports to evaluate representative files.
