What this PDF task means
OCR (optical character recognition) identifies text in images and converts it into machine-readable text that can be searched, copied, or processed. Scanned PDFs may look like text pages but contain only page images. OCR adds a text layer; recognition quality depends on scan clarity, language, and layout.
When this method is useful
Scanned PDFs may look like text pages but contain only page images. OCR adds a text layer; recognition quality depends on scan clarity, language, and layout. Choose a workflow that matches the document, its intended recipient, and any quality or privacy requirements.
Step-by-step guide
- Run OCR on a copy of the scanned PDF, select the correct language when supported, process the file, then search for several words and compare extracted text with the page image.
- Download or save the processed file to a clearly named location.
- Open the output independently and verify the result before relying on it.
Quality and safety checklist
- Straighten skewed scans, use adequate resolution, and proofread names, numbers, and tables. OCR is not guaranteed to be error-free.
- Keep the source file until the output has passed review.
- Use a trusted service for sensitive or confidential documents.
Common mistakes to avoid
- Treating OCR output as verified
- ignoring language settings
- assuming tables and columns will always be reconstructed accurately.
