# Convert dense PDFs into LLM-ready text and page-aligned markdown with olmOCR

Use olmOCR when an agent needs to turn scanned or layout-heavy documents into clean markdown or text before chunking, search, extraction, or citation workflows.

## Prerequisites

Python 3.11, pip or conda, poppler-utils, optional NVIDIA GPU for local inference

## Installation

Use the upstream install or setup path that matches your environment:
- conda create -n olmocr python=3.11
- conda activate olmocr
- pip install olmocr
- pip install olmocr[gpu] --extra-index-url https://download.pytorch.org/whl/cu128

Requirements and caveats from upstream:
- (Based on a 7B parameter VLM, so it requires a GPU)
- June 17, 2025 - v0.1.75 - Switch from sglang to vllm based inference pipeline, updated docker image to CUDA 12.8.
- May 23, 2025 - v0.1.70 - Official docker support and images are now available! [See Docker usage](#using-docker)

Basic usage or getting-started notes:
- #### System Dependencies
- You will need to install poppler-utils and additional fonts for rendering PDF images.
- bash
