About CR3 to ODD Conversion
Canon CR3 is the RAW format used by Canon's EOS R mirrorless system, including the R5, R6, R7, and R3. It uses a HEIF-based container with CRAW compressed RAW data processed by Canon's DIGIC X engine. ODD (OpenDocument Drawing) is LibreOffice Draw's vector drawing format for creating annotated diagrams and technical illustrations. Converting CR3 to ODD demosaics the Canon sensor data and embeds the resulting photograph into an editable Draw document.
This conversion serves Canon mirrorless photographers who need to incorporate their captures into technical documentation, annotated reports, or illustrated presentations using LibreOffice's free, open-source drawing tools.
Why Convert CR3 to ODD?
Canon EOS R cameras capture extremely high-resolution images — the R5 at 45 MP, the R5 Mark II at 45 MP with computational photography — that are ideal for detailed technical documentation. Converting to ODD lets you annotate these captures with dimension callouts, labels, and vector shapes directly in LibreOffice Draw.
The ODD format follows the ISO 26300 OpenDocument standard, making it the preferred choice for government, academic, and institutional environments that mandate open-standard document formats for official documentation and reporting.
Common Use Cases
- Annotate Canon EOS R5 architectural photography with measurement callouts for construction documents
- Create illustrated product inspection reports from Canon R6 captures in LibreOffice Draw
- Build technical documentation pages combining Canon mirrorless photos with vector diagrams
- Prepare annotated visual presentations from Canon EOS R series photography
How It Works
The conversion reads the CR3 HEIF-based container, decodes the CRAW compressed RAW data from Canon's DIGIC X pipeline, performs demosaicing and color correction using the embedded metadata, and embeds the resulting RGB image into an ODD XML package. The ODD file stores the raster image alongside XML content definitions within a ZIP container.
Quality & Performance
The embedded photograph retains the full demosaiced quality from Canon's high-resolution sensor. The ODD wrapper introduces no additional compression to the raster data. Canon's DIGIC X color science is applied during the RAW-to-RGB conversion, producing accurate colors for technical documentation.

Tips for Best Results
- 1Use Draw's dimensioning tools to add precise measurement annotations on architectural and product photography
- 2Export the annotated ODD to PDF for cross-platform sharing of your documented Canon captures
- 3For multi-image reports, place different Canon R series photos on separate pages within one ODD document
- 4Keep original CR3 files for future re-processing — the ODD contains a processed raster, not RAW data
CR3 to ODD conversion integrates Canon EOS R mirrorless photography into LibreOffice Draw's vector editing environment, enabling professional technical documentation with annotated high-resolution captures.
