Common uses

When OCR PDF is useful

Make scanned PDF pages searchable with English OCR.

01

Make a scanned agreement searchable before review.

02

Prepare an image-only invoice for text or table extraction.

03

Create copyable text from photographed English pages.

Important boundary

OCR always needs human verification.

Do not rely on recognized text for legal, medical, financial or identity data without checking the visible scan.

Practical help

Questions before you run it

Does OCR translate the document?

No. It recognizes English characters and keeps the visible page image.

Why is the output larger?

Every page is rendered into an image-backed searchable PDF.

Can it read handwriting?

Handwriting accuracy is not promised; use clear printed text for best results.
