OpenOffice to PDF Converter

How Do You Convert OpenOffice Files to PDF?

You convert OpenOffice files to PDF by adding them to QuickCatPDF's OpenOffice to PDF converter and clicking Convert to PDF. Text documents, spreadsheets, presentations and drawings from Apache OpenOffice or LibreOffice (ODT, ODS, ODP and ODG) all become PDFs, without installing either suite.

The tool is free, needs no sign-up and adds no watermark. It also opens the older StarOffice formats SXW, SXC and SXI.

How to Convert OpenOffice Documents With QuickCatPDF

Converting OpenDocument files takes four steps.

1. Click Select files or drop your documents on the page. You can mix text, spreadsheet and presentation files, up to 10 at once.
2. Check the settings for each kind of file: Paper size for text documents, Page fit and Sheets for spreadsheets, Slides per page for presentations.
3. For several files, choose Separate PDFs or One combined PDF.
4. Click Convert to PDF, then download each PDF, the ZIP or the combined PDF.

Why Use QuickCatPDF for OpenOffice and LibreOffice Files?

QuickCatPDF converts OpenDocument files with LibreOffice itself, running on our own server. OpenDocument is LibreOffice's native format, so styles, frames, tables, charts and page layouts are read by the same software that most likely created them, not by an imitation.

The settings panel adapts to what you add: text documents, spreadsheets and presentations each get their own options, and they all convert in one go. In our test, an ODT, an ODS and an ODP file converted together in under 4 seconds.

Files are sent over HTTPS and deleted when conversion ends; the PDFs are deleted right after your browser downloads them, and nothing is kept more than 1 hour.

Which OpenOffice Formats Can You Convert?

Each OpenDocument type has its own page with options tuned for it, and all of them also work here.

The same converter takes Microsoft Office files too, so a DOCX and an ODT can go into one combined PDF.

What Is the Difference Between OpenOffice and LibreOffice Files?

There's no difference in the files. Apache OpenOffice and LibreOffice both save in the OpenDocument Format, an open ISO standard (ISO/IEC 26300), so an ODT from one opens in the other. "OpenOffice file" and "LibreOffice file" mean the same thing here.

LibreOffice began in 2010 as a continuation of OpenOffice.org and is now the more actively developed of the two, which is why our server uses it.

Why Convert OpenDocument Files to PDF?

PDF is the safest way to send an OpenDocument file to someone who uses different software. Not everyone has an office suite that reads ODT or ODS files, and those that do can lay them out slightly differently. A PDF looks the same everywhere, prints exactly, and can't be changed by accident.

If your file uses fonts that aren't on our server, similar fonts are used instead; embedding fonts when you save in LibreOffice (File, Properties, Font) avoids this. Password-protected files need the password removed first.
