Optical character recognition (OCR) is a technology that extracts text from images. It scans GIF, JPG, PNG, and TIFF images. If you turn it on, the extracted text is then subject to any content compliance or objectionable content rules you set up for Gmail messages.
For example, say you configured your content compliance setting so that messages with credit card numbers are moved to quarantine. A customer sends you a message with a PNG image attachment of an invoice that contains a credit card number. If you turn on OCR, Gmail converts the image attachment to text, detects the credit card number, and moves the message to quarantine.
Note: OCR doesn’t scan images embedded in attached files, such as Adobe PDF or Microsoft Word documents. And, it's not always 100% accurate. Sometimes, it doesn’t detect content that triggers a compliance setting action.
