How MKD works
MKD turns heavy documents into lean Markdown so ChatGPT, Claude and other AI tools burn far fewer tokens. Three steps, no sign-up, all in your browser.
Three steps
Drop a file
Drag in a PDF, slide deck, Word doc, spreadsheet or image. Everything is parsed locally in your browser — nothing is uploaded.
Get lean Markdown
MKD extracts the text and structure into a compact .md file — no images, no layout baggage, just content.
Paste into your AI chat
Copy the Markdown or download the file and drop it into ChatGPT, Claude or any LLM. Same content, a fraction of the tokens.
Supported formats
Whatever your document looks like, MKD turns it into clean, token-friendly Markdown:
PDF to Markdown
One Markdown section per page, with reading-order text extraction.
PPT / PPTX / ODP to Markdown
One section per slide — titles become headings, bullets stay bullets.
Word: DOC, DOCX, ODT & RTF
Headings, lists and tables preserved — including legacy .doc files.
Excel: XLSX, XLS & ODS
Every worksheet becomes a tidy Markdown table.
Images to Markdown (OCR)
PNG, JPG, WEBP, GIF, BMP, TIFF and AVIF text is recognized right in your browser.
Email (EML) to Markdown
Sender, recipients, subject and message body become a clean .md summary.
EPUB, HTML, XHTML & SVG
Ebooks, web pages and SVG labels become structured, readable Markdown.
CSV & TSV to Markdown
Spreadsheet exports become clean Markdown tables, quoted fields included.
JSON, YAML, TOML, XML & IPYNB
Config, data and notebook files keep their syntax in fenced code blocks.
Markdown, MDX, code & plain text
MD, MDX, JS, TS, Python, SQL, logs, LaTeX, subtitles and any other text file.
ZIP to Markdown
Convert supported files inside one archive into a single combined .md file.
Why Markdown saves tokens
AI tools charge you in tokens for everything you upload. PDFs and slide decks carry heavy formatting, fonts and layout data 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 — and your free quota lasts much longer.
Use it as AI context
The converted .md file is ready to adapt into prompts, agent instructions, reference material or reusable knowledge snippets. Turn lecture notes into study context, operating procedures into agent instructions, and project documents into searchable knowledge for your AI workflow.
Students
Convert readings and lecture slides into compact study context.
Professionals
Turn reports, decks and spreadsheets into prompt-ready notes.
Operations teams
Adapt SOPs and internal docs into reusable agent instructions.
