Markdrop

A Python package for converting PDFs to structured Markdown and interactive HTML, with AI-powered image and table descriptions across six major LLM providers. Available on PyPI.

Features

• PDF → Markdown conversion with formatting preservation (via Docling)
• Automatic image extraction using XRef IDs
• Table detection using Microsoft's Table Transformer
• PDF URL support
• AI-powered image and table descriptions — 6 providers: Gemini, OpenAI, Anthropic Claude, Groq, OpenRouter, LiteLLM
• Interactive HTML output with downloadable Excel tables
• Customisable image resolution and UI elements
• Structured logging (never pollutes your app's root logger)

Installation

Core install (PDF conversion + Gemini/OpenAI):

pip install markdrop

With Anthropic Claude:

pip install "markdrop[anthropic]"

With Groq:

pip install "markdrop[groq]"

With LiteLLM (routes to 100+ providers):

pip install "markdrop[litellm]"

Everything (including local HuggingFace models):

pip install "markdrop[all]"

Faster CPU / lightweight Markdown (--fast mode):

pip install "markdrop[lite]"
markdrop convert report.pdf --output_dir out --fast

See docs/cpu-guide.md for CPU-only and Colab guidance.

OpenRouter is accessed through the openai package (already included in core), so no extra install is needed.

Supported AI Providers

All models are configurable — use --model to override for any provider, or set model_name_override in ProcessorConfig.

Quick Start

See examples/quickstart.md for copy-paste commands.

CLI Usage

Check the installed version:

markdrop --version

1. Convert PDF → Markdown + HTML

markdrop convert <input_path> --output_dir <dir> [--add_tables] [--fast]

# Example
markdrop convert report.pdf --output_dir out --add_tables
# Outputs: out/report-markdroped.md and out/report-markdroped.html

# Also works with URLs (SSRF-protected download):
markdrop convert https://arxiv.org/pdf/1706.03762 --output_dir out

2. Generate AI Descriptions for Images & Tables

markdrop describe <markdown_file> --ai_provider <provider> [--output_dir <dir>] [--remove_images] [--remove_tables]

# Gemini (default)
markdrop describe doc.md --ai_provider gemini

# Anthropic Claude
markdrop describe doc.md --ai_provider anthropic --remove_images

# Groq (fastest inference)
markdrop describe doc.md --ai_provider groq

# OpenRouter (any model)
markdrop describe doc.md --ai_provider openrouter

# LiteLLM (unified gateway)
markdrop describe doc.md --ai_provider litellm

3. Set Up API Keys

markdrop setup <provider>

Keys are stored in your user config directory (via platformdirs, with a fallback to ~/.config/markdrop/):

• Linux/macOS: ~/.config/markdrop/.env (or $XDG_CONFIG_HOME/markdrop/.env)
• Windows: %LOCALAPPDATA%\markdrop\.env

On POSIX systems, the .env file is written with 0o600 permissions.

markdrop setup gemini       # → GEMINI_API_KEY (GOOGLE_API_KEY also accepted)
markdrop setup openai       # → OPENAI_API_KEY
markdrop setup anthropic    # → ANTHROPIC_API_KEY
markdrop setup groq         # → GROQ_API_KEY
markdrop setup openrouter   # → OPENROUTER_API_KEY
markdrop setup litellm      # → LITELLM_API_KEY

4. Analyze Images in a PDF

markdrop analyze report.pdf --output_dir pdf_analysis --save_images

5. Batch Image Description Generation

markdrop generate images/ --output_dir descriptions/ --prompt "Describe in detail." \
  --llm_client gemini openai

Available --llm_client values: qwen, gemini, openai, llama-vision, molmo, pixtral

Python API

PDF Conversion

from markdrop import markdrop, MarkDropConfig, add_downloadable_tables
from pathlib import Path
import logging

config = MarkDropConfig(
    image_resolution_scale=2.0,
    download_button_color="#444444",
    log_level=logging.INFO,
    log_dir="logs",
    excel_dir="markdrop-excel-tables",
)

html_path = markdrop("path/to/input.pdf", "output", config)
downloadable_html = add_downloadable_tables(html_path, config)

AI Descriptions

import asyncio
from markdrop import process_markdown, ProcessorConfig, AIProvider, setup_keys

# One-time key setup (writes to user config ~/.config/markdrop/.env)
setup_keys("anthropic")

config = ProcessorConfig(
    input_path="out/report-markdroped.md",
    output_dir="output",
    ai_provider=AIProvider.ANTHROPIC,  # GEMINI | OPENAI | ANTHROPIC | GROQ | OPENROUTER | LITELLM
    remove_images=False,
    remove_tables=False,
    table_descriptions=True,
    image_descriptions=True,
    max_retries=3,
    retry_delay=2,
    # Override default models (all providers have matching config fields):
    anthropic_model_name="claude-opus-5",
    anthropic_text_model_name="claude-sonnet-5",
)

output_path = asyncio.run(process_markdown(config))

Using OpenRouter to access any model

config = ProcessorConfig(
    input_path="doc.md",
    output_dir="output",
    ai_provider=AIProvider.OPENROUTER,
    openrouter_model_name="meta-llama/llama-4-scout",  # any model on openrouter.ai/models
    openrouter_text_model_name="anthropic/claude-sonnet-5",
    openrouter_site_url="https://yoursite.com",
    openrouter_site_name="My App",
)

Using LiteLLM for any 100+ provider

import os

os.environ["ANTHROPIC_API_KEY"] = "..."  # set any provider's key

config = ProcessorConfig(
    input_path="doc.md",
    output_dir="output",
    ai_provider=AIProvider.LITELLM,
    litellm_model_name="anthropic/claude-opus-5",
    litellm_text_model_name="openai/gpt-5.6-luna",
)

Batch Image Description Generation

from markdrop import generate_descriptions

generate_descriptions(
    input_path="images/",
    output_dir="output/",
    prompt="Give a highly detailed description of this image.",
    llm_client=["gemini", "llama-vision"],
)
