name: pdf-tools description: View, extract, edit, and manipulate PDF files. Supports text extraction, text editing (overlay and replacement), merging, splitting, rotating pages, and getting PDF metadata. Use when working with PDF documents for reading content, adding/editing text, reorganizing pages, combining files, or extracting information.

PDF Tools

Tools for viewing, extracting, and editing PDF files using Python libraries (pdfplumber and PyPDF2).

Quick Start

All scripts require dependencies:

pip3 install pdfplumber PyPDF2

Core Operations

Extract Text

Extract text from PDF (all pages or specific pages):

scripts/extract_text.py document.pdf
scripts/extract_text.py document.pdf -p 1 3 5
scripts/extract_text.py document.pdf -o output.txt

Get PDF Info

View metadata and structure:

scripts/pdf_info.py document.pdf
scripts/pdf_info.py document.pdf -f json

Merge PDFs

Combine multiple PDFs into one:

scripts/merge_pdfs.py file1.pdf file2.pdf file3.pdf -o merged.pdf

Split PDF

Split into individual pages:

scripts/split_pdf.py document.pdf -o output_dir/

Split by page ranges:

scripts/split_pdf.py document.pdf -o output_dir/ -m ranges -r "1-3,5-7,10-12"

Rotate Pages

Rotate all pages or specific pages:

scripts/rotate_pdf.py document.pdf -o rotated.pdf -r 90
scripts/rotate_pdf.py document.pdf -o rotated.pdf -r 180 -p 1 3 5

Edit Text

Add text overlay on a page:

scripts/edit_text.py document.pdf -o edited.pdf --overlay "New Text" --page 1 --x 100 --y 700
scripts/edit_text.py document.pdf -o edited.pdf --overlay "Watermark" --page 1 --x 200 --y 400 --font-size 20

Replace text (limited, works best for simple cases):

scripts/edit_text.py document.pdf -o edited.pdf --replace "Old Text" "New Text"

Note: PDF text editing is complex due to the format. The overlay method is more reliable than replacement.

Workflow Patterns

Viewing PDF Content

1. Get basic info: scripts/pdf_info.py file.pdf
2. Extract text to preview: scripts/extract_text.py file.pdf -p 1
3. Extract full text if needed: scripts/extract_text.py file.pdf -o content.txt

Reorganizing PDFs

1. Split into pages: scripts/split_pdf.py input.pdf -o pages/
2. Merge selected pages: scripts/merge_pdfs.py pages/page_1.pdf pages/page_3.pdf -o reordered.pdf

Extracting Sections

1. Get page count: scripts/pdf_info.py document.pdf
2. Split by ranges: scripts/split_pdf.py document.pdf -o sections/ -m ranges -r "1-5,10-15"

Advanced Usage

Notes

• Page numbers are 1-indexed in all scripts (page 1 = first page)
• Text extraction works best with text-based PDFs (not scanned images)
• Rotation angles: 90, 180, 270, or -90 (counterclockwise)
• All scripts validate file existence before processing

这个 PDF 处理工具集功能齐全，能满足日常的文本提取、合并、分割、旋转等需求。文档详细清楚，安装使用都比较简单。主要问题是文本编辑功能受 PDF 格式限制较大，添加水印功能相对可靠，但替换文本容易出错。对于简单的 PDF 操作需求来说是个好选择。
