Prompt
Do I need OCR if most of my inputs are PDFs and scanned documents?

Yes — if a lot of your inputs are scanned documents or image-based PDFs, you’ll usually need OCR.
Why
- Scanned PDFs often contain just page images, not actual selectable text.
- OCR (Optical Character Recognition) converts those images into machine-readable text.
- Without OCR, you can’t reliably search, extract, or analyze the contents.
When you may not need OCR
You may not need it if your PDFs are mostly:
- Digital/text-based PDFs created from Word, LaTeX, or similar
- Documents where text is already embedded and selectable
Practical rule
- Mostly scanned/image PDFs? Use OCR.
- Mostly native PDFs with selectable text? OCR is optional, only for fallback on bad scans.
Common approach
A lot of systems do:
- Try to extract embedded text first
- If text is missing or poor quality, run OCR on the pages
- Combine both outputs into one pipeline
If you want, I can also help you decide between:
- cloud OCR vs open-source OCR
- OCR only on scanned pages vs all pages
- a recommended document-ingestion pipeline
