What Is an OCR Translation API?
An OCR Translation API (Application Programming Interface) is a service that combines Optical Character Recognition (OCR) with machine translation. It allows developers to programmatically send images or scanned documents (like PDFs) to an API, which first extracts the text and then translates it into a target language. Instead of a multi-step manual process, a developer can use a single, integrated workflow to make visual content multilingual. These APIs are the engine behind automated document processing, global compliance, and digitizing international archives, offering features like layout preservation, language detection, and batch processing. For businesses, selecting the best OCR translation API is crucial for maintaining quality and context from scanned source materials.
