Are animations preserved?

ODP (OpenDocument Presentation) is the native presentation format for LibreOffice Impress and Apache OpenOffice Impress, standardized under ISO/IEC 26300. The file is a ZIP archive holding slide XML, master slide definitions, embedded media, and theme references. It's the default save format in Impress on every Linux distribution and is mandated in many European and South American government environments where Microsoft PowerPoint dependence is explicitly prohibited. Educational institutions in Germany, Brazil, and India often ship ODP curricula materials.

Converting ODP to HEIC rasterizes each slide as one HEIC image at the presentation's set slide size - typically 1920x1080 for modern 16:9 decks, 1024x768 for legacy 4:3, or custom for poster decks - at roughly half the file size of JPG output. Embedded images, charts, Impress diagrams, shapes, text boxes, and master slide backgrounds all render as they appear in Impress's slide-show view, with HEIC's 10-bit color keeping gradient backgrounds band-free. Animations, transitions, and slide-by-slide builds collapse to their final state since the output is static. Speaker notes are stripped (they live on the notes view, not the slide).

Teachers archiving Impress decks as compact slide images, presenters AirDropping slides to an iPad for rehearsal, and anyone storing large deck libraries in iCloud where the 40-50% size saving over JPG compounds fast are the natural audiences. For posting to platforms that reject HEIC (most CMSes and social networks), convert the output via HEIC to JPG. For editable handoff to PowerPoint use Impress's File > Save As > .pptx. For sharing animations export to video from File > Export first, then frame-extract via MP4 to HEIC. Slide dimensions match the canvas: a 1920x1080 deck produces 1920x1080 images.

Reasons to convert ODP to HEIC usually come down to compatibility, file-size, or specific feature requirements. Common situations:

• An app or platform only accepts HEIC uploads.
• You need a feature unique to HEIC (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that ODP doesn't provide.
• You're optimising file size — modern formats often produce smaller files than the older format you started with.
• You need a single archival format across a project so files behave consistently in the same viewer.

1. Open the ODP → HEIC tool on heic.now.
2. Drag your ODP file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
3. The output is fixed to HEIC. If the format supports extra options (page size, transparency background, quality, EXIF stripping), tweak them in the right-hand panel.
4. Click Convert. The job runs on our server and finishes in a few seconds for typical photos.
5. Download the result. Files stay in storage for 24 hours and are then permanently deleted.

The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.

• Set a custom slide size before designing if your target is LinkedIn (1080x1080) or Instagram (1080x1350) - resizing after layout breaks alignment. And remember to convert those slides to JPG before uploading; most social platforms reject HEIC.
• Hide background images on title slides via Slide > Slide Properties > Background for a clean white export suitable for print handouts.
• Animations and builds collapse to their final visible state - design slides that read sensibly without animation if you'll be exporting to static images.
• Use the Outline view in Impress to verify text content survives the export - decorative text inside grouped shapes sometimes renders unexpectedly.
• For multilingual decks, embed fonts via Tools > Options > Load/Save > General > Embed Fonts to ensure CJK and Cyrillic characters render correctly on conversion servers.
