Converting ODT to PDF File: A Complete Guide

Quick Answer:

• Method 1. Print ODT to PDF with Word Processor (Universal Option)
• Method 2. Convert ODT to PDF with Online Converter like CloudxDocs
• Method 3. Convert ODT to PDF with Dedicated Code Library

In today’s digital-first world, the ability to manage and share documents effectively is an essential skill for individuals, students, and businesses alike. While multiple file formats exist, two of the most widely used ones are ODT (Open Document Text) and PDF (Portable Document Format).

If you’ve ever worked with an ODT file created using LibreOffice, Apache OpenOffice, or similar open-source word processors, you may have noticed compatibility issues when sharing the file with people who primarily use Microsoft Word or expect a universally accessible format. That’s where converting ODT to PDF becomes a necessity.

In this blog post, we’ll walk through why PDF is the go-to format for sharing documents, explore various methods for converting ODT to PDF files, and introduce a quick and efficient online solution like CloudXDocs.

Why Convert ODT to PDF?

Many people overlook the importance of file formats. Actually, the file type can significantly affect how your document is displayed, shared, and even perceived by others. An ODT file might be perfectly fine for personal use or within teams who use LibreOffice or OpenOffice, but the moment you step outside that ecosystem you may encounter compatibility issues.

The following list shows some main reasons why you should convert ODT to PDF format:

• Universal Accessibility: PDF is the gold standard for file sharing because it can be opened across devices and operating systems without the need for special software. Whether your recipient is on Windows, macOS, Linux, Android, or iOS, a PDF ensures seamless access.
• Preserves Formatting: One of the biggest issues with ODT files is formatting inconsistencies. A document might look perfect in LibreOffice but appear broken in Microsoft Word. Converting to PDF locks in the layout, fonts, images, and structure.
• Professionalism: Businesses and academic institutions often require PDF submissions because the format is associated with professionalism, security, and long-term archiving.
• Security Features: Unlike ODT, PDFs can be password-protected, encrypted, or watermarked, making them ideal for sharing sensitive documents.
• Smaller File Size: With compression options, PDFs can often be optimized to reduce file size without losing clarity, which is particularly useful when emailing attachments or uploading online.

There’s no single method for converting ODT to PDF, and the best option depends on your workflow, tools, and preferences. Below are some of the most popular ways.

Method 1. Print ODT to PDF with Word Processor (Universal Option)

Most modern operating systems now come with a built-in “Print to PDF“ feature, making it one of the simplest and most universal methods to convert an ODT file into a PDF.

This approach is especially convenient for users who don’t want to rely on third-party tools or online services, and it works across Windows, macOS, and many Linux distributions. However, while it’s quick and accessible, keep in mind that advanced formatting, hyperlinks, or interactive elements may not always carry over perfectly.

The steps of printing ODT file with PDF format are listed below:

Step 1. Open your ODT file in any word processor, for example, Microsoft Word.

Step 2. Go to “File“ > “Print“ from the Ribbon.

Step 3. Select “Print to PDF“ as the printer. Then you have successfully converted ODT files to PDF format.
