SmartArt diagrams contribute their text, so the full slide story survives the conversion.\nYou choose what is converted. Select slides with the PageRange parameter, include hidden slides on request, and bring in each slide's speaker notes as quote blocks: the narrative that usually lives only in the presenter's notes becomes part of the document, often the most valuable text a deck holds for retrieval. Password protected presentations are accepted.\nThe Images parameter decides what happens to the pictures in a presentation. Use embed for one self contained file, extract to get the images as separate files, remove for the most compact text, or describe to let an AI model turn images into text: scanned paragraphs and tables are transcribed, charts and photos get short descriptions, and decorative images are dropped. The last option produces text only Markdown for LLM and RAG pipelines.\nSimply upload your PowerPoint presentation and receive a structured Markdown file ready for publishing, search, or AI ingestion.\n",
