pdf-image-extractor

Extract images from PDFs in original, 800x800 web-ready, or compressed under 50KB formats for printing, e-commerce, or social media use.

Security Scan

The skill's code, instructions, and requirements match its stated purpose (extracting and resizing images from PDFs); there are no network calls, credential requests, or unexpected behaviors in the shipped scripts.

Purpose & Capability

Name and description align with the provided scripts: three modes (original, standard, compress) implemented in local Python scripts using PyMuPDF and Pillow. There are no unrelated credentials, binaries, or config paths requested.

Instruction Scope

SKILL.md instructs installing Python packages, editing the top-of-file CONFIG variables (pdf_folder/output_folder), and running the appropriate script. The scripts only read PDFs from the configured folder and write images to the configured output; they do not access other system resources, network endpoints, or environment variables.

Install Mechanism

There is no formal install spec; the README asks the user to pip install pymupdf and pillow. The repository includes runnable Python scripts (no external downloads or extract steps). Recommend using a virtualenv when installing dependencies to avoid changing global Python packages.

Credentials

No environment variables, credentials, or external config paths are required. The scripts use local file-system paths only (user must edit pdf_folder/output_folder). Default config values point to a Windows E:\ path, which is a convenience/default but not a security-sensitive requirement.

Persistence & Privilege

The skill is not forced-always, and it does not modify agent/system configuration. It runs as a normal user process and only writes extracted images to the configured output folder.

Assessment

This package appears to do exactly what it says: extract and resize images from PDFs locally. Before using: 1) Inspect and, if desired, edit the pdf_folder and output_folder paths in each script so they point to safe folders; 2) Run pip installs inside a Python virtual environment; 3) Test on a small, non-sensitive PDF set first to confirm behavior; 4) Note the default config targets a Windows E:\ path—change it if you are on another OS; 5) If you need network isolation, run the scripts offline or in a sandbox/VM—these scripts do not perform any network calls according to the source.

Extract images from PDF files with three output modes.

Three Modes

Mode	Command	Best For
Original	python scripts/extract_original.py	Printing, high-quality
Standard	python scripts/extract_standard.py	Website, e-commerce
Compress	python scripts/extract_compress.py	WeChat, Douyin, social

Quick Start

# Install dependencies
pip install pymupdf pillow

# Configure
# Edit CONFIG section at top of each script:
# - pdf_folder: Path to your PDF folder
# - output_folder: Where to save images

# Run
python scripts/extract_original.py    # Original quality
python scripts/extract_standard.py    # 800x800 square
python scripts/extract_compress.py    # Compressed sharing
