About WMZ to ODD Conversion
Converting WMZ to ODD (OpenDocument Drawing) transforms gzip-compressed Windows Metafile vector graphics into an editable open-standard drawing document. ODD files are part of the OpenDocument Format (ODF) specification used natively by LibreOffice Draw, providing a cross-platform editable container for the vector content originally locked inside Windows-specific WMZ files.
This conversion is particularly valuable for organizations migrating from Microsoft-centric workflows to open-source alternatives. WMZ graphics embedded in legacy Office documents, Windows applications, and enterprise systems can be extracted and converted to ODD for continued editing and maintenance in LibreOffice Draw without requiring Windows or Microsoft Office licenses.
Why Convert WMZ to ODD?
WMZ files require Windows GDI rendering for correct display and are editable only in applications that understand the WMF format — primarily Microsoft Office. Converting to ODD opens these graphics to LibreOffice Draw and other ODF-compliant editors on Windows, macOS, and Linux. The vector content becomes fully editable — shapes can be resized, text can be changed, colors can be modified — in a free, open-source environment.
ODD also provides better long-term format sustainability than WMZ. As an ISO-standardized format (ISO 26300), ODD has guaranteed specification availability and multiple independent implementations. WMZ relies on Microsoft's proprietary GDI rendering, which receives decreasing attention in newer Windows versions. For archival and institutional purposes, ODD offers stronger format longevity.
Common Use Cases
- Migrate WMZ graphics from Microsoft Office to LibreOffice Draw for continued editing without Windows
- Convert enterprise WMZ diagrams to open-standard ODD format for vendor-independent archival
- Extract and edit WMZ clip art in LibreOffice Draw on macOS and Linux systems
- Transform Windows-specific WMZ graphics into ISO-standardized ODD for institutional document systems
- Enable cross-platform collaborative editing of vector graphics originally created as WMZ on Windows
How It Works
The gzip compression envelope is stripped to extract the WMF content. The WMF's GDI drawing records are interpreted and translated into equivalent ODF drawing primitives — draw:line, draw:rect, draw:ellipse, draw:path, draw:text-box, and draw:image elements. The output is packaged as an ODD file (a ZIP archive containing content.xml with drawing elements, styles.xml with formatting, meta.xml with metadata, and any embedded bitmap resources). The conversion preserves vector editability where possible, converting GDI commands to their closest ODF equivalents.
Quality & Performance
Vector elements (lines, rectangles, ellipses, basic paths) translate well from WMF's GDI commands to ODD's ODF drawing primitives. Text rendering may differ if the WMZ uses Windows-specific fonts that are not available in LibreOffice. Complex GDI operations without direct ODF equivalents are rasterized as embedded bitmaps within the ODD container. For typical business diagrams and organizational charts, the conversion preserves full editability.

Tips for Best Results
- 1Install Microsoft core fonts on your LibreOffice system for better WMZ text rendering fidelity
- 2Review the converted ODD in LibreOffice Draw and manually adjust any elements that did not translate perfectly
- 3Use ODD as the ongoing editable master format and export to PDF or PNG for distribution
- 4For batch migration of WMZ libraries, test a representative sample before converting the entire collection
- 5Keep original WMZ files as backup until you have verified the ODD conversions are satisfactory
WMZ to ODD converts proprietary compressed Windows metafiles into editable open-standard drawings, enabling continued editing in LibreOffice Draw and long-term format sustainability under ISO standardization.
