Convert ODT to PDF online
Convert OpenDocument Text to PDF to share a LibreOffice or OpenOffice document with someone who does not have either. ODT is the native format of open-source office software, and PDF is what the rest of the world opens without asking questions.
When should you convert ODT to PDF?
- Send an ODT document to a colleague using Microsoft Office
- Submit a file to a form or a portal that requires PDF
- Print a document with a layout that holds
- Archive a document in a widely readable format
Before you convert
This is the most reliable direction
LibreOffice is the engine doing the conversion and ODT is its native format, so the layout comes across as accurately as any conversion here.
Fonts still matter
The server substitutes fonts it does not have. Stick to common typefaces if the exact look is important.
What happens to your file
LibreOffice opens the ODT headlessly with its Writer filter and exports PDF. Writer, Calc, and Impress each have their own permitted output set — LibreOffice will not convert across those categories, so the allowed targets here are Writer's.
Settings this conversion runs with
| Engine | LibreOffice headless (Writer) |
|---|---|
| Output | |
| Font handling | Missing fonts detected and substituted before rendering |
What changes
- If the document uses a font the server does not have, a substitution is picked before rendering — a close match, not the original. Line breaks and page counts can shift as a result, which is why it is worth opening an important file before sending it on.
- Right-to-left documents get an extra pass: justification is normalized before rendering so Arabic paragraphs do not come out stretched or misaligned, and a known-bad Arabic font is swapped for one the renderer handles correctly.

- Why your converted document changed fonts
Document converters render on a server that does not have your fonts. Here is what substitution does to your layout, why Arabic and CJK documents are affected most, and how to avoid the surprise.
