Markdown Tools
PPTX to MD PHP Overview
Convert PowerPoint presentations (PPT/PPTX) into clean, readable Markdown built for AI applications, LLM ingestion, embeddings, RAG pipelines, and documentation workflows. Every slide becomes a section under its title heading, bullet levels turn into nested Markdown lists, tables become Markdown tables, and charts are recovered as tables of their data points. SmartArt diagrams contribute their text, so the full slide story survives the conversion.
You 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.
The 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.
Simply upload your PowerPoint presentation and receive a structured Markdown file ready for publishing, search, or AI ingestion. Includes a ready-to-use PHP SDK.

Customizable Parameters

File
File Supported formats: .ppt .pptxFile to be converted. Value can be URL or file content.
PageRange
String Default: 1-2000Set page range or individual pages to convert. Example 1-10 or 1,2,5.
Password
StringSets the password to open protected documents.
Images
Collection Default: embedControls how images are handled in the resulting Markdown. Embed produces a self-contained document with images embedded as base64 data URIs. Extract saves images as separate files referenced by relative links, the result is a zip archive with the Markdown and image files, or a plain Markdown file when the document has no images. Remove replaces images with their alt text when available, producing compact output suited for machine processing. Describe replaces every image with AI generated text: scanned text and tables are transcribed, pictures become short descriptions, producing text-only Markdown for LLM and RAG scenarios.
ListBulletChar
Collection Default: -The character used to mark bullet list items. Markdown allows a hyphen, an asterisk or a plus sign, all three are rendered the same.
Values: - * +SlideHeadings
Bool Default: TrueWrite each slide's title as a Markdown heading above its content, or the slide number when a slide has no title. When disabled, slides are separated by a horizontal rule instead.
IncludeSpeakerNotes
Bool Default: FalseAppend each slide's speaker notes after its content as a quote block.
ConvertHiddenSlides
Bool Default: FalseInclude hidden slides while converting.
StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
