About Document Converter

Dozens of pairs exist between office formats; the dedicated pages cover the common ones and this converter covers the rest — DOCX to ODT, PPTX to ODP, ODP to PPTX, TXT to DOCX, PDF to ODT and more.

Everything runs through a LibreOffice engine on our server, the most complete open implementation of these formats. Output is deleted within one hour of conversion.

How it works

  1. Drop your files onto the box above, click it to browse, or paste from the clipboard.
  2. Adjust the options if you need to — the defaults suit most cases.
  3. Press Convert. The file is uploaded securely, converted, and the result is offered for download.
  4. Download the result — individually or all at once.

About the formats

Word (DOCX) · Microsoft Word document · .docx

The current Word format (since 2007): a ZIP of XML files that Word, Google Docs, LibreOffice and Pages can all open and edit.

  • DOCX layout depends on the fonts installed on the viewing computer, which is why the same file can paginate differently on another machine.
  • Converting to PDF freezes the layout so it looks the same everywhere.
  • DOCX is part of the Office Open XML standard (ISO 29500).

Word 97–2003 (DOC) · Legacy Microsoft Word document · .doc

The binary Word format used from 1997 to 2003; still opens in Word, but many web apps and phones cannot read it.

  • DOC files are binary, not XML, so they cannot be inspected or repaired as easily as DOCX.
  • Google Docs converts DOC on upload; Word opens it in Compatibility Mode.
  • Macros can live inside DOC files, so some email systems block them.

ODT · OpenDocument text · .odt

The open document format used by LibreOffice and OpenOffice Writer, and required by several governments for public documents.

  • ODT is an ISO standard (ISO 26300) and fully documented, unlike DOC.
  • Word can open and save ODT, but complex formatting may shift.
  • Like DOCX, an ODT file is a ZIP archive containing XML.

RTF · Rich Text Format · .rtf

A 1987 Microsoft interchange format that almost any word processor can read: bold, italics, lists and tables, but no modern layout features.

  • RTF is plain text with control codes, so it is safe from macros and easy to repair.
  • Images are stored as hexadecimal text, which makes RTF files with pictures very large.
  • Windows WordPad and macOS TextEdit both save RTF by default.
