What ODF is
ODF, the OpenDocument Format, is an open international standard (ISO/IEC 26300) for office documents. It is the native format of LibreOffice and Apache OpenOffice, and many governments and schools use it. The family includes:
| Extension | Type | Made with |
|---|---|---|
| .odt | Text document | LibreOffice Writer |
| .ods | Spreadsheet | LibreOffice Calc |
| .odp | Presentation | LibreOffice Impress |
| .odg | Drawing | LibreOffice Draw |
Why convert ODF to PDF
Many people use Microsoft Office or only a phone, and they may not be able to open ODF files, or see them with a broken layout. A PDF opens everywhere and looks the same. Because the conversion uses LibreOffice itself, the program that ODF files are made for, the result is very faithful: text documents keep their styles and tables, spreadsheets are printed with their print ranges, presentations become one page per slide, and drawings keep their vector shapes.
Good to know
Fonts that are not available on our server are replaced by similar ones. Spreadsheets follow the page settings stored in the file, so set a print range and the page orientation before converting wide sheets. Animations in presentations are not part of a PDF. Password-protected files cannot be converted; remove the password first.
If you have LibreOffice yourself, you can also export a single document to PDF there, with File, Export as PDF. This converter is useful when LibreOffice is not at hand, for example on a phone or on a borrowed computer, or when you need to convert many files at once and combine them into one PDF.
Privacy and limits
Files are converted on our own server. They are uploaded over HTTPS, converted, and deleted right after; the PDF is kept for 15 minutes at most. Up to 20 files at once, each up to 100 MB. The same converter also handles Microsoft formats: see Word to PDF, Excel to PDF and PPT to PDF.
