About HEIC to ODD conversion
ODD is the older file extension for OpenDocument Drawing files, the vector drawing format used by LibreOffice Draw and the legacy Apache OpenOffice Draw application. Modern LibreOffice versions (5.x and later) write the format with the .odg extension by default, but .odd remains supported for compatibility with OpenOffice 3.x, NeoOffice, and StarOffice files created between 2005 and 2012. Converting HEIC to ODD decodes your iPhone photo and wraps it inside an OpenDocument Drawing container so it can be opened, annotated, and combined with vector shapes inside LibreOffice Draw.
The ODD format is XML-based, ZIP-compressed, and ISO/IEC 26300 standardized - the same open standard underlying ODT (text), ODS (spreadsheet), and ODP (presentation). Because most ODF applications ship without an HEVC decoder, the converter first decodes the HEIC (a full-quality decode of the HEVC image data) and embeds the result as a standard raster Picture object on the drawing canvas, with EXIF orientation applied. Page size defaults to A4 portrait but can be changed to any custom dimension in Draw's Format > Page Style dialog after opening. The resulting file is roughly the decoded image size plus a few KB of container overhead - larger than the compact HEIC source, since the space-efficient HEVC encoding can't survive the embed.
Government agencies, public-sector institutions in Germany, Brazil, and India, and academic users on Linux distributions where ODF is the mandated default format are the primary audience - the exact environments where iPhone HEIC attachments otherwise refuse to open. Once inside Draw, the photo can be cropped, rotated, annotated with arrows and text boxes, combined with imported SVG and PNG assets into a multi-page layout, or bundled onward to PDF - or skip Draw entirely and go straight to HEIC to PDF. For modern LibreOffice workflows the .odg variant is preferred; use .odd only when the recipient explicitly requires the older extension.
Where ODD comes from
ODD (OpenDocument Drawing) was standardised as ISO/IEC 26300 in 2006, derived from the OpenDocument Format developed by the OASIS consortium for the OpenOffice project. The format is a ZIP archive containing XML descriptions of vector shapes, embedded raster images and styling, similar in spirit to OOXML but fully open. LibreOffice Draw uses ODD (also written .odg) as its native format. Governments in regions including France, the Netherlands, Brazil and several Indian states mandate ODF for public records. Because LibreOffice's HEIC support depends on system codecs that Linux desktops rarely ship, decoding the HEIC during conversion is the reliable route into an editable drawing.
HEIC vs ODD at a glance
| HEIC | ODD | |
|---|---|---|
| Compression | HEVC intra-frame (lossy or lossless) | ZIP container holding XML and an embedded raster |
| Transparency | Full alpha channel | Vector overlays support alpha |
| Typical file size (12 MP photo) | 1.5-2.5 MB | 2-4 MB (decoded raster plus wrapper) |
| Best for | iPhone capture, mobile sharing | LibreOffice Draw editing |
| Animation | Yes (Live Photos, bursts) | No |
| Bit depth | 8 or 10-bit | 8-bit embedded raster |
| Browser support | Safari only | None (download only) |
Real-world workflow — Open-source designer annotates an iPhone photo of a whiteboard
- Photograph the whiteboard UI sketch with an iPhone — it saves as HEIC
- Convert to ODD, since LibreOffice Draw cannot open HEIC directly
- Add callout arrows, text labels and highlight boxes on top
- Save and share with the dev team — they can edit the annotations too
Recommended conversion settings
| Use case | Settings |
|---|---|
| Annotated screenshot | Embed the decoded HEIC at 100 percent, add vector callouts |
| Floor plan overlay | Scale the photo to page, lock as background |
| Diagram with photo backdrop | Raster layer plus vector shapes on top |
| Multi-page document | One HEIC per page, A4 portrait |

When to convert HEIC to ODD
Converting HEIC to ODD is a common workflow requirement wherever different software systems, platforms, and applications need to exchange image or document content. Whether you are preparing files for web publishing, print production, client delivery, or meeting upload requirements, having the right format is the starting point for every distribution workflow.
HEIC files are tied to specific software ecosystems and tools. When that content needs to move into a context that requires ODD - A different editing environment, a submission portal, a print service, or a sharing platform - A fast, reliable converter removes the format barrier without requiring software installation or technical knowledge.
heic.now processes your file securely in the cloud and returns a clean ODD output that meets the format specification of standard applications and platforms. Files are processed privately and automatically deleted after 24 hours - Nothing is stored beyond what is needed to complete your conversion.
HEIC to ODD tips
- Save as .odg (not .odd) if your audience uses LibreOffice 5.0 or later - the newer extension is identical content but registered by default in current installs.
- After opening in Draw, use Tools > Macros > Edit to scriptably batch-annotate hundreds of imported photos with identical text overlays.
- Page size defaults to A4 - change via Format > Page Style if your iPhone photo is panoramic or square and you want a tight crop fit.
- ODD files are ZIP archives - rename to .zip and extract to recover the embedded picture, but note it's the decoded raster, not the original HEIC, so keep your source file.
- For Apache OpenOffice 4.x users on Windows or older Macs, .odd opens directly via File > Open; no conversion plugin needed.
