Good to know
Password-protected or DRM-protected files cannot be processed. Upload an unlocked copy you are authorized to use.
Scanned PDFs
If each page is an image, use optical character recognition (OCR) before uploading. To check, try selecting and copying a sentence from the PDF. If you cannot, the file likely needs OCR.
