Extracting text and images can facilitate data migration when transitioning from one document format to another. Extracted content can be preserved in a more accessible and editable format, reducing the risk of data loss.

Embedded images and text can be extracted independently of the PDF document. The extracted text will be in a normal string, while the extracted images will be in image buffer format and can then be exported or further processed.

Use the extractText method to extract text, and the extractRawImages method to extract images from a PDF document.
