About ICO to ODD Conversion
ICO (Windows Icon) files contain one or more icon images at different sizes (16x16, 32x32, 48x48, 256x256) and color depths, used for application icons, desktop shortcuts, and favicons. ODD (OpenDocument Drawing) is LibreOffice Draw's format for annotated vector-and-raster documents.
Converting ICO to ODD extracts the highest-resolution icon image and embeds it into an editable Draw document. This is useful for UI designers documenting icon sets, creating annotated icon style guides, and building visual specification sheets for application design projects.
Why Convert ICO to ODD?
Icon design documentation requires showing icons alongside annotations explaining their usage, sizing requirements, and design rationale. Converting ICO files to ODD places each icon on a Draw canvas where designers can add labels describing the icon's purpose, note pixel dimensions, and indicate where each size variant should be used.
LibreOffice Draw's vector tools complement the raster icon with scalable annotation elements, creating professional icon specification documents that can be shared as ODD or exported to PDF.
Common Use Cases
- Create annotated icon specification sheets for UI design documentation
- Build icon style guides with labeled usage examples in LibreOffice Draw
- Document Windows application icon sets with size and context annotations
- Prepare visual asset inventories of ICO icon libraries with descriptive metadata
How It Works
The conversion extracts image data from the ICO container, selecting the highest-resolution layer (typically 256x256 PNG-compressed or 48x48 BMP). The extracted image is embedded into an ODD XML package. ICO files may contain multiple size variants; the conversion uses the largest available size for maximum quality.
Quality & Performance
The extracted icon image retains its full quality including any alpha channel transparency. Icons are small images (typically 16-256 pixels per side), so the embedded image in the ODD is correspondingly compact. Vector annotations in Draw remain crisp at any zoom level.

Tips for Best Results
- 1Place icons on a grid layout in Draw to create organized icon set documentation sheets
- 2Use Draw's text tool to label each icon with its filename, dimensions, and intended use context
- 3For icon style guides, add color palette swatches as Draw shapes alongside the converted icons
- 4Export icon documentation ODD files to PDF for sharing with development teams
ICO to ODD conversion enables icon design documentation in LibreOffice Draw, providing annotated specification sheets and style guides from Windows icon assets.
