Technical Specs: PDF

  • Structure: A PDF is not a simple text file. It contains a Header, a Body (objects like fonts, images, text streams), a Cross-Reference Table (XREF) to locate objects, and a Trailer.
  • AcroForms: Standard forms use key-value pairs stored within the PDF structure. Retrieving user input requires parsing these specific object dictionaries.
  • MIME Type: application/pdf.

Frequently Asked Questions

Why can’t I select text in the “Scanned” PDF?
Because it is just a picture of a document inside a PDF container. To make it selectable, you must run it through an OCR (Optical Character Recognition) tool like Tesseract or Adobe Acrobat Pro to generate a hidden text layer.
Can I edit a PDF file programmatically?
It is difficult. PDF is designed for “Output”, not editing. However, you can fill form fields, add annotations, or merge pages using libraries like PDF.js, PyPDF2, or iText. Modifying existing text paragraphs usually breaks the layout.

How to process PDF files?

Working with PDFs often requires specialized libraries for rendering or scraping data.

  • PDF.js (Mozilla): The standard library to render PDFs in a web browser using JavaScript. Used by Firefox.
  • Tesseract OCR: The open-source engine by Google to extract text from scanned PDFs.
  • LibreOffice Draw: Surprisingly capable tool to edit PDF text and layout graphically for free.

Developer’s Corner: Text Extraction

To scrape data from invoices or reports, use pdfplumber. It is slower than PyPDF2 but much better at handling tables and layout.

# Python: Extract text and tables
import pdfplumberwith pdfplumber.open(“invoice.pdf”) as pdf:
page = pdf.pages[0]
# Extract simple text
print(page.extract_text())
# Extract table data
print(page.extract_table())
