Choose the clearest image: upright text, adequate resolution, strong contrast, and little glare. Run image to text, then compare the extracted text with the source instead of treating a plausible paragraph as exact.
Check names, amounts, dates, punctuation, and similar characters such as O and 0. Tables and multi-column layouts can lose reading order. For important documents, preserve the source image and verify every value used in a decision or calculation.
OCR makes text editable; it does not certify that the transcription is accurate.
