What is ODT?

ODT (OpenDocument Text) is the default format for LibreOffice Writer and OpenOffice. While it's an open standard, not everyone has software to open it - PDF ensures universal compatibility.

  • LibreOffice users - share documents with anyone as PDF
  • Formatting preserved - layout, fonts, and styles stay intact
  • Universal - PDF opens on any device without special software

About Converting ODT to PDF

ODT is the native word-processing format of LibreOffice and OpenOffice, and an open ISO standard. It is often converted to DOCX for people who use Microsoft Word. When you need to move away from ODT, the usual reason is simple: microsoft office support is imperfect.

Converting your ODT document to PDF solves that. PDF is the universal fixed-layout document format. It freezes fonts, images and layout so a file looks identical on every device, which is why it is the standard for contracts, invoices and reports. In practice you gain identical appearance on every device and universally supported. PrivConvert runs the whole ODT-to-PDF conversion in server memory and deletes your file the instant the PDF is ready — nothing is stored, logged or reused.

When this conversion helps

  • You need identical appearance on every device
  • You need universally supported
  • You need supports encryption, signatures and forms
  • Sharing a ODT document with someone whose software expects PDF

Tips for best results

  • Files up to 250 MB are supported, and you can batch-convert several ODT files at once; each is processed privately and deleted immediately.
