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, 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.

Java

<dependency>
	<groupId>io.github.mini-software</groupId>
	<artifactId>minipdf</artifactId>
	<version>0.1.6</version>
</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.

Python

pip install minipdf

import minipdf

minipdf.convert_to_pdf("report.docx", "report.pdf")

The Python guide lists the current DOCX feature scope and CLI options.

Node.js

npm install minipdf

const 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

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

import 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.

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.
• 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.
