OCRmyPDF vs Regula Document Reader SDK

OCRmyPDF is free software that adds searchable text to scanned PDF files while retaining the original PDF as much as possible. It uses Tesseract to recognize text in page images and produces PDF/A-2b by default, with regular PDF output available as an alternative. Image-processing options such as deskew can adjust pages to support visual quality and OCR accuracy. When a PDF already contains text, its processing modes can stop with an error, skip affected pages, redo OCR, or force OCR across all pages. OCRmyPDF can also be used as a Python library, and plugins can customize processing steps. Installation methods are documented for Linux, macOS, Windows, FreeBSD, and Docker; Paperless-ngx and Nextcloud OCR are named as third-party integrations. Results may be poor for low-quality scans or languages not specified for processing, and handwriting is not recognized. The project also notes that accuracy may trail commercial solutions. Its documentation advises processing only PDFs users trust and warns that its example Docker web service has no security measures and is not meant for public internet deployment.

Regula Document Reader SDK reads identity-document data and checks document quality and authenticity for identity verification services. Regula says its database contains more than 16,500 document types from 254 countries and territories. Depending on component and license, checks can include visual-zone OCR, MRZ and barcode processing, RFID chip reading, image quality assessment, and authenticity checks. The SDK supports passports, ID cards, driver's licenses, visas, mobile driver's licenses, and other identity documents. Mobile driver's license verification can use QR codes and NFC, with retrieval via Bluetooth and NFC. Integration options include mobile SDKs, browser web components, a web service, direct API integration, and connection with Regula Face SDK. The web service can be deployed through Linux package repositories, Windows installers, Docker images, or cloud options such as AWS. A free trial is listed at free, billed 30 days, with 2,000 transactions and no feature limits. Custom licensing uses flexible pricing based on usage and business needs, with pricing on request. Offline licensing is limited to desktop and the Document Reader Web Service on Windows and is unavailable for Docker.
