Frequently asked questions
Everything about converting PDFs, slide decks and documents into token-friendly Markdown.
How do I convert a PDF to Markdown for ChatGPT?
Drop your PDF into the box on the home page, wait a few seconds, then click Download .md or Copy Markdown. Paste the result into ChatGPT, Claude or any other AI chat instead of uploading the original file.
How do I convert a PPT or PPTX deck to Markdown?
Drop the .ppt or .pptx file into the converter. Each slide becomes its own Markdown section — the slide title turns into a heading and the slide content stays as bullets, so the structure of your deck is preserved.
Is this PDF to Markdown converter free?
Yes — MKD is 100% free with no sign-up and unlimited conversions. Convert as many PDFs, decks and documents as you like.
Are my files uploaded anywhere?
No. All conversion happens locally in your browser. Your documents never leave your device and nothing is stored on a server.
Why does Markdown save tokens?
AI tools charge you in tokens for everything you upload. PDFs and slides carry heavy formatting and layout data that the model doesn't need. Markdown keeps the text and structure but strips the bloat, so the same content costs a fraction of the tokens.
Can I use the Markdown as AI agent instructions or knowledge context?
Yes. The .md output works well as prompt context, reference material, reusable instructions or knowledge snippets for ChatGPT, Claude and AI agents. Headings, lists, tables and readable sections are preserved where the source file includes them.
What is a .md file?
A .md file is plain text written in Markdown — a simple format using symbols like # for headings and - for bullets. Any AI chat, note app or editor can read it, no special software needed.
Can it read text inside images or scanned PDFs?
Images (PNG, JPG, WEBP) run through in-browser OCR, so printed text is recognized and converted to Markdown. Scanned PDFs with no embedded text layer may return little text — export the pages as images and convert those instead.
