Frequently Asked Questions
What is the difference between OCR PDF and PDF to Text?
PDF to Text extracts text that is natively embedded as text characters in the PDF — instant and 100% accurate. OCR PDF visually reads scanned images of text using machine learning — necessary for documents that are photographs or scans with no embedded text layer.
Will OCR modify my original PDF or create a new one?
OCR creates a new output PDF with an invisible searchable text layer added over the original scan. Your original document pages remain visually identical — only text search and copy functionality is unlocked.
