How to make a scanned PDF searchable

Create the scanned PDF

1. A scan normally contains page images rather than selectable characters. OCR adds a best-effort text layer that can be searched and copied.
2. Create an ordered PDF from clear, upright page images.
3. Current OCR recognizes printed English and must be checked for important details.
4. Use PDF to Text or PDF to Word after OCR when the recognized text needs to be reused.

Create a clean source PDF

Capture pages in even lighting, keep the camera parallel to the paper, and make the printed text large enough to read. Use Scan to PDF to arrange the images.

1. Capture or select the page images.
2. Arrange and rotate them correctly.
3. Create the source PDF.

Run OCR on the scanned pages

OCR PDF renders each page, recognizes printed English, and adds a searchable text layer. Handwriting, curved pages, tables, and low contrast can reduce accuracy.

1. Open OCR PDF and choose the scan.
2. Start recognition and wait for every page.
3. Search and copy sample text in the result.

Reuse the recognized text

PDF to Text produces a plain-text copy. PDF to Word creates an editable DOCX, but complex reading order and layout remain best-effort.

1. Choose PDF to Text for simple extraction.
2. Choose PDF to Word when a DOCX is required.
3. Verify names, dates, and amounts before relying on the text.
