Questions about this tool
Does OCR change the visual appearance of the PDF?
A good OCR workflow keeps the original page image and adds a text layer, but the output must still be checked for page alignment and recognition errors.
Why can OCR text be wrong?
Scan quality, skew, low contrast, unusual fonts and language selection directly affect recognition accuracy.
Can I rely on OCR text for legal or technical data?
Not without review. Verify names, numbers, dates and other critical fields against the original page image.
