Technical Limitations

This tool relies on extracting text data from the PDF file. Therefore, it has the following limitations:

  • It only works with PDFs that contain selectable text. It will not work on scanned documents or PDFs that consist only of images.
  • The accuracy of line numbering depends on the structure of the PDF. Complex layouts with multiple columns or tables might not be numbered correctly.
  • Very large PDF files may cause performance issues in the browser.
