About Converting DOCX to ODT

DOCX is the modern Microsoft Word format — a ZIP package of XML. It is compact, resistant to corruption and editable in Word, Google Docs, Pages and LibreOffice. When you need to move away from DOCX, the usual reason is simple: layout can shift slightly between apps.

Converting your DOCX document to ODT solves that. 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. In practice you gain open iso standard and fully editable. PrivConvert runs the whole DOCX-to-ODT conversion in server memory and deletes your file the instant the ODT is ready — nothing is stored, logged or reused.

When this conversion helps

  • You need open ISO standard
  • You need fully editable
  • You need free of vendor lock-in
  • Sharing a DOCX document with someone whose software expects ODT

Tips for best results

  • After converting, open the ODT and skim the formatting — complex layouts occasionally need a small touch-up.
  • Files up to 250 MB are supported, and you can batch-convert several DOCX files at once; each is processed privately and deleted immediately.
