Converting OpenDocument to PDF: what to know
When you need it
ODT is the OpenDocument text format used by free office suites and by many public administrations. Readers who use Word or a phone often find an ODT opens badly or not at all; a PDF solves that for everyone.
What to expect
ODT documents convert with very high fidelity: text, styles, tables and images come out laid out as in the original. Fonts that aren't available on the server are replaced with similar ones.
Tip: If the recipient needs to edit the file in Word rather than just read it, convert ODT to DOCX instead.

What is OpenDocument?
ODT is the OpenDocument text format, an international open standard and the default in free office suites. It is fully editable and vendor-neutral, and Microsoft Word and Google Docs can open it, sometimes with small layout differences.
What is PDF?
PDF preserves a document's exact layout, fonts and images so it looks the same on every device and printer. It is the standard for sharing, signing and archiving final documents, but it is designed to be read rather than edited.
Tips for converting OpenDocument to PDF
- Fonts that are not installed on our servers are replaced with similar ones, so check the layout of the converted file.
- Scanned documents are images: converting a scanned OpenDocument will not make its text editable (that requires OCR).
- Complex layouts, macros and embedded objects may not survive every conversion; review the PDF before sharing it.
- Password-protected files cannot be converted — remove the password first.
