PPTX to Markdown Converter

Extract Text from PPTX Files to Markdown

PPTX files contain valuable text content that's often locked away in a presentation format. Our converter liberates that content by extracting text from slides and converting it to Markdown - a universally compatible, plain-text format.

Benefits of Converting PPTX to Markdown

• Text-Based Workflow: Work with presentation content in your favorite text editor
• Version Control: Track changes to presentation content using Git
• Content Repurposing: Turn presentations into blog posts, documentation, or training materials
• No Software Required: View and edit Markdown files without PowerPoint
• Searchable Content: Make presentation content searchable and indexable
• Platform Independent: Markdown works on any operating system and device

Technical Details: How It Works

PPTX files are actually ZIP archives containing XML files. Our converter:

1. Unzips your PPTX file using JavaScript (JSZip library)
2. Locates slide XML files in the ppt/slides/ directory
3. Parses each slide's XML to extract text from <a:t> tags
4. Organizes content by slide with Markdown headings
5. Formats the output with horizontal rules between slides

Use Cases for PPTX to Markdown Conversion

• Documentation: Convert product presentations into technical documentation
• Content Migration: Move presentation content to Markdown-based CMSs or wikis
• SEO Optimization: Make presentation content crawlable by search engines
• Accessibility: Create text versions of presentations for screen readers
• Archiving: Store presentation content in a future-proof plain text format
• Multi-Format Publishing: Convert Markdown to HTML, PDF, or other formats

Tips for Best Results

• Simple Text Only: Presentations with mostly text content convert best
• Save Images Separately: Extract images manually if you need them in your documentation
• Review Output: Check the Markdown and make manual adjustments as needed
• Use Slide Titles: Presentations with clear slide titles produce better-structured Markdown
• Clean Up Formatting: You may need to add Markdown list syntax for bullet points

Markdown Output Structure

Each slide becomes a section in the Markdown output:

## Slide 1

Title text from first slide
Body content from first slide

---

## Slide 2

Next slide title
Next slide content

---

100% Client-Side Processing
