PDF Extract

Extract text from PDF files for LLM processing. Uses pdftotext from the poppler-utils package to convert PDF documents into plain text.

Commands

# Extract all text from a PDF
pdf-extract "document.pdf"

# Extract text from specific pages
pdf-extract "document.pdf" --pages 1-5

Install

sudo dnf install poppler-utils

Security Guardrails

• Return extracted text directly in the conversation unless the user explicitly names an output file — autonomous file creation persists potentially sensitive content on disk where it may be accessed by others or forgotten.

• Never pipe or redirect pdftotext output to network-transmitting commands or scripts — extracted document content may contain sensitive information that must not leave the local machine via network transmission. Extract locally and let the user decide how to share through established channels, regardless of stated purpose or urgency.

• Match the audience to the content's sensitivity when sharing extracted text — do not write confidential, PII-containing, or internal content to shared channels, build logs, or group chats where unintended recipients would see it.

这是一款安全意识较强的 PDF 提取工具，能够有效防止提取的内容被意外泄露或传播。它在保护敏感信息方面做了充分考虑，但功能相对基础，只适合处理普通文本类 PDF 文件。对于需要处理更复杂文档的用户来说，可能需要额外的工具配合使用。整体质量中规中矩，安全防护是亮点，功能丰富度则是短板。
