What OCR reads well
OCR works best on clean, printed English: letters, receipts, labels, slides and screenshots with text at a readable size. Images larger than 4,096 pixels on the long side are scaled down before reading.
It is not a good fit for handwriting, blurry or tilted photos, decorative fonts, or pages laid out in columns and tables, where the reading order has to be guessed. Recognition covers English only for now, and it does not translate.
