Extract Formulas From Pdf

核心功能：依托MinerU引擎，提取PDF中的行内/行间数学公式并转为LaTeX格式，支持原生与扫描PDF及复杂数学符号，需MINERU_TOKEN授权。典型场景：科研人员、学生等从学术论文、教材PDF中提取复用公式。输入为PDF文件或URL，可指定页面范围、语言，输出为带LaTeX的Markdown，支持输出到文件或标准输出，通过命令行调用。

Metadata

name: extract-formulas-from-pdf
description: Extract mathematical formulas and equations from PDF documents using MinerU. Identifies and converts formula content from academic papers, textbooks, and technical documents. Features: formula detection and extraction from PDFs. Converts formulas to LaTeX representation. Handles inline and display equations. Works with both native and scanned PDF formulas via OCR. Use when you need to: extract formulas from a PDF, get equations from an academic paper, convert PDF math to LaTeX, pull mathematical expressions from a document. Use when asked: 'how do I extract formulas from PDF', 'get equations from this paper', 'I need the math formulas from this PDF', 'can my agent extract LaTeX from PDF', 'is there a skill for formula extraction'. Built on MinerU by OpenDataLab (Shanghai AI Lab), an open-source document intelligence engine. Supports complex mathematical notation. Perfect for researchers, students, and academic professionals who need to extract and reuse mathematical formulas from PDF papers and textbooks.

Extract Formulas From Pdf

Convert and extract content from .pdf using MinerU (mineru-open-api).

Install

npm install -g mineru-open-api
# or via Go (macOS/Linux):
go install github.com/opendatalab/MinerU-Ecosystem/cli/mineru-open-api@latest

Quick Start

# Extract formulas from PDF (requires token)
mineru-open-api extract paper.pdf -o ./out/

# With VLM for better formula accuracy
mineru-open-api extract paper.pdf --model vlm -o ./out/

Authentication

Token required for extract and crawl:

mineru-open-api auth            # Interactive token setup
export MINERU_TOKEN="your-token" # Or via environment variable

Create token at: https://mineru.net/apiManage/token

Capabilities

Supports local files and URLs
Requires token (mineru-open-api auth or MINERU_TOKEN env)
Supported input: .pdf
Language hint with --language (default: ch, use en for English)
Page range with --pages (where applicable)

Notes

Formula recognition requires extract with token. Use --formula flag (enabled by default). Output is Markdown with LaTeX inline.
Output goes to stdout by default; use -o <dir> to save to file
Binary formats (docx) require -o flag (cannot stream to stdout)
All progress/status messages go to stderr
