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.

dotnet add package MiniPdfusing MiniSoftware;

MiniPdf.ConvertToPdf("report.docx", "report.pdf");Prefer a command-line tool?

dotnet tool install --global MiniPdf.Cli

minipdf report.docx -o report.pdfThe .NET guide covers conversion, custom fonts, CLI options, and deployment.

cargo add minipdf

cargo install minipdf-climinipdf::convert_to_pdf("report.docx", "report.pdf")?;minipdf report.docx -o report.pdfThe Rust guide documents the crate API, CLI, supported features, known gaps, and development workflow.

</dependency>Maven group IDs may contain hyphens, but Java package names may not. Therefore,

the dependency uses io.github.mini-software, while imports use

io.github.minisoftware.minipdf.

import io.github.minisoftware.minipdf.MiniPdf;

import java.nio.file.Files;

import java.nio.file.Path;

try {

MiniPdf.registerFont(

"Noto Sans",

Files.readAllBytes(Path.of("fonts/NotoSans-Regular.ttf")));

MiniPdf.convertToPdf(Path.of("report.docx"), Path.of("report.pdf"));

} finally {

MiniPdf.clearRegisteredFonts();

}Registered fonts are used by DOCX, XLSX, and PPTX conversion. Registrations are process-wide; clear them before configuring a different font set.

pip install minipdfimport minipdf

minipdf.convert_to_pdf("report.docx", "report.pdf")The Python guide lists the current DOCX feature scope and CLI options.

npm install minipdfconst minipdf = require('minipdf')

minipdf.convertToPdf('report.docx', 'report.pdf')The Node.js guide covers in-memory conversion, page sizing, font registration, and supported native platforms.

go get github.com/mini-software/MiniPdf/minipdf-go@latestimport minipdf "github.com/mini-software/MiniPdf/minipdf-go"

if err := minipdf.ConvertToPDF("report.docx", "report.pdf"); err != nil {

panic(err)

}The Go guide documents the package, native CLI, current rendering scope, and release tags.

- 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.

- Multiple language options: use MiniPdf from .NET, Rust, Java, Python, Node.js, or Go.

- Native command-line options: available for .NET, Rust, Java, Python, and Go.

- 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.
