How it works
Convert in 3 simple steps
Upload your file
Drag & drop or select any PDF, DOCX, Markdown, LaTeX, YAML, or image file. Free tier supports up to 10 MB, higher tiers up to 100 MB.
Choose Standard or Knowledge Pack
Select a plain output format like Markdown, PDF, EPUB, Text, JSON, or CSV — or generate a full AI Knowledge Pack with metadata, citations, and structure. Enable AI mode for higher quality output on Pro and Enterprise plans.
Preview & download

Features
AI Knowledge Pack infrastructure for developers & writers
Every conversion format developers and writers need — with AI-powered extraction, post-clean processing, batch support, CLI, and REST API included, all built around one goal: turning your documents into AI-ready Knowledge Packs.
AI Knowledge Packs
Purpose-built output for ChatGPT, Claude, Gemini, Cursor, RAG pipelines, and vector databases. Includes Markdown, metadata, document outline, citations, images, tables, code blocks, and a JSON manifest — all in one ZIP.
In active beta. Works great for docs, tutorials, and reports. Dense academic PDFs with heavy equations may see reduced fidelity — we're improving this weekly.
PDF → Markdown Docs
Convert any PDF into a structured Markdown document with clean formatting.
DOCX → Markdown Docs
Convert Word documents into AI-ready Markdown documents without losing formatting, styles, or document structure.
AI Clean (Post-processing)
After conversion, an AI pass fixes formatting artifacts, cleans up broken Markdown, and improves structure quality. Powered by Claude. Pro and Enterprise plans.
Image OCR → Text
Extract text from scanned documents, screenshots, and images. Supports English, Arabic, Urdu and 13 more languages including neural OCR for complex scripts.
