Text copied from a scanned PDF contains wrong characters

OCR can misread unclear or closely spaced characters. Compare the copied text with the original image before using it in another document.

By RJ Computers

Quick answer

OCR can misread unclear or closely spaced characters. Compare the copied text with the original image before using it in another document.

Understand the issue

Commonly troublesome material includes small print, skewed pages and faint photocopies. Keep examples of the errors so you can decide whether to correct a few words or rescan the source. Do not replace the original scan with unreviewed extracted text.

Step-by-step checks

  1. Compare a short copied passage against the visible page.
  2. Inspect the OCR language and recognition results.
  3. Correct identified errors or rescan an unreadable source at suitable quality.
