Unlock the hidden text in your scanned documents and image-based PDFs by learning how to programmatically OCR PDFs to create searchable documents using the pdfRest OCR PDF API Tool. This advanced REST API tool leverages state-of-the-art Optical Character Recognition (OCR) technology to convert scanned documents and images within PDFs into accurately recognized, searchable, and extractable text. If you're looking for a powerful solution to programmatically OCR PDFs, pdfRest transforms static documents into dynamic, usable data, significantly enhancing your document management and data processing workflows.

Why Programmatically OCR PDFs to Create Searchable Documents?

Transform Non-Searchable PDFs: Convert image-based or scanned PDFs into fully searchable documents, making previously inaccessible text selectable, searchable, and copyable.
Boost Efficiency and Accuracy: Automate text recognition and extraction, eliminating the need for manual data entry and significantly saving development time and resources.
Improve Data Accessibility: Enhance user workflows by enabling easy highlighting, copying, and searching of text directly within images present in the PDF.
Enable Comprehensive Text Extraction: Serve as an essential pre-processing step for the Extract Text API Tool, ensuring all text, including rasterized content, is extractable.
Streamline Document Management: Implement robust OCR PDF solutions to effectively manage large volumes of scanned files, turning them into dynamic data sources for archiving, analysis, and compliance.

Why Choose pdfRest API for Programmatic PDF OCR?

Supports Image-Based Text Extraction: Designed specifically to address the challenge of text trapped within scanned documents or PDFs containing embedded images, ensuring all content is recognized.
Seamless PDF and OCR Integration: Our API offers a developer-friendly, frictionless integration experience with well-documented references and readily available code samples, allowing you to implement OCR workflows with minimal code and effort.
Multi-Language Support: Specify a comma-separated list of languages (e.g., English, German, French, Chinese, Japanese, Korean) for the OCR engine to recognize, optimizing accuracy for multilingual documents.
State-of-the-Art OCR Technology: Leverages advanced OCR algorithms to provide high accuracy in text recognition.
Scalable and Reliable: Built for consistent performance, capable of handling large volumes of scanned files efficiently.

How to Programmatically OCR PDFs with pdfRest

Here's a simple example of how to use cURL to send a request to the pdfRest API to programmatically OCR a PDF to make its text searchable, specifying a language:

curl -X POST "https://api.pdfrest.com/pdf-with-ocr-text" \
  -H "Accept: application/json" \
  -H "Content-Type: multipart/form-data" \
  -H "Api-Key: YOUR_API_KEY" \
  -F "file=@/path/to/your_scanned_document.pdf" \
  -F "languages=English,Spanish" \
  -F "output=searchable_document"

Replace YOUR_API_KEY with your actual pdfRest API key and adjust the file path to your PDF document. You can specify multiple languages (comma-separated) for accurate recognition.
