About HEIC to ODD Conversion
HEIC (High Efficiency Image Container) is Apple's default photo format on iPhones and iPads since iOS 11, using HEVC compression to produce files roughly half the size of equivalent JPEGs. ODD (OpenDocument Drawing) is LibreOffice Draw's vector drawing format for annotated mixed-media documents.
Converting HEIC to ODD decodes the HEVC-compressed image data and embeds it into an editable Draw document. This is practical for iPhone users who need to incorporate their photos into annotated reports, technical documentation, or presentation materials created in LibreOffice Draw.
Why Convert HEIC to ODD?
HEIC files from iPhones cannot be opened natively on many Windows and Linux systems without installing additional codecs. Converting to ODD provides cross-platform accessibility while adding annotation capability. Teachers, researchers, and field workers who capture reference photos on iPhones can create annotated documentation directly from their mobile captures.
ODD's ISO 26300 standard ensures the annotated documents are accessible on any platform, making it ideal for institutional workflows that combine iPhone photography with LibreOffice-based document production.
Common Use Cases
- Create annotated field documentation from iPhone HEIC photographs in LibreOffice Draw
- Build illustrated lesson materials from iPad camera captures with descriptive overlays
- Prepare annotated visual reports from iPhone site inspection photography
- Convert iPhone photos for inclusion in LibreOffice Draw presentation boards
How It Works
The conversion decodes the HEVC (H.265) compressed image data from Apple's HEIC container, which may include depth maps and Live Photo motion data (these auxiliary data are discarded). The primary still image is extracted at full resolution and embedded into an ODD XML package.
Quality & Performance
HEIC's HEVC compression is lossy but highly efficient — iPhone photos at default settings show no visible compression artifacts. The ODD conversion preserves the decoded image at full quality without additional recompression.

Tips for Best Results
- 1Use this conversion for field documentation workflows where iPhone photos need immediate annotation
- 2Draw's callout tools are ideal for labeling objects and features in iPhone site inspection photos
- 3Export annotated ODD documents to PDF for sharing field reports with team members
- 4For large batches of iPhone photos, convert to JPEG first for viewing, and to ODD only for photos that need annotation
HEIC to ODD conversion bridges iPhone photography into LibreOffice Draw's annotation environment, making Apple's default photo format accessible for cross-platform documentation workflows.
