How scanner apps writes PDFs
- • Scans are images of the page, sometimes with a hidden text layer from OCR.
- • The visible text is pixels, not letters.
What that means when you compare two versions
- • Scanned pages are pictures of text. Use OCR PDF to make them searchable; typing into a scan is a separate, image based process.
What happens to the rest of the page
- • The differences between the two files are highlighted.
- • Useful before sending a revised draft.
