Text PDFs vs. Scanned PDFs
Not all PDFs are equal. There are two fundamentally different types:
- Text PDFs: Created digitally (from Word, for example). You can select, copy, and search the text inside.
- Scanned PDFs: A paper document photographed and saved as PDF. In reality, it is just images — you cannot select text, copy it, or search it.
OCR converts the second type into the first — it reads the images, extracts the text, and embeds it into the PDF to make it fully searchable and copyable.
