When text extraction works
Text extraction works on PDFs that contain embedded text — documents created in Word, Google Docs, or any PDF writer. Scanned PDFs that are just images of pages do not contain text data and will return empty results.
Page range syntax
Use 1,3,5-7 to extract pages 1, 3, 5, 6, and 7. Leave the field empty to extract the full document.
