Amazon Textract

Amazon Textract supports PNG, JPEG, TIFF, and PDF formats.

An image (PNG, TIFF, or JPEG) counts as a single page. For PDFs, each page in the document is counted as a page processed.

The most common use cases include importing documents and forms into business applications, creating smart search indexes, building automated document processing workflows, maintaining compliance in document archives, extracting text for Natural Language Processing (NLP), and extracting text for document classification.

Amazon Textract can detect printed text and handwriting from the Standard English alphabet and ASCII symbols. It can extract printed text, forms, and tables in English, German, French, Spanish, Italian, and Portuguese.

To get the best results, ensure your document uses a supported language, provide high-quality images (ideally at least 150 DPI), and avoid converting or downsampling documents before uploading. Tables work best when visually separated and upright.

Amazon Textract supports logging actions as CloudTrail events, including DetectDocumentText, AnalyzeDocument, StartDocumentTextDetection, StartDocumentAnalysis, GetDocumentTextDetection, and GetDocumentAnalysis.

You can request a service limit increase by logging into the AWS Console, navigating to the AWS Service Quotas console, selecting 'Textract,' choosing the desired quota, and clicking 'Request Quota Increase.'

Best practices include implementing retry logic, configuring exponential backoff and jitter, smoothing traffic flow, using IDP CDK Samples, and estimating quota requirements with the Textract Service Quota calculator.
