Include images (base64)

Disabled by default. When enabled, embedded slide images will be included as base64 data URIs in the JSON. Useful if your AI task needs visual data — for example multimodal analysis or extracting diagrams — but increases JSON size and processing time. For text-only summarization or indexing, keep this off.

Images and AI — when to include them

Images are off by default because most AI text tasks (summarization, indexing, extracting slide bullet points) don't need visuals. Enable images if you plan to do multimodal analysis, diagram extraction, or OCR on slide graphics. Base64 images make the JSON much larger; consider extracting only the images you need or using external hosting for large presentations.
