Online OCR - How to use it
The OCR.space Online OCR service converts images and PDF documents into editable text files using Optical Character Recognition (OCR). The service also supports creating searchable PDF documents.
Our Online OCR service is free to use with no registration required. Simply upload your image files in JPG, PNG, GIF, or PDF format. The service supports multi-page documents and multi-column text recognition. The free tier has a file size limit of 5MB per document.
For automated OCR processing and batch document conversion, please use our free OCR API instead of web-scraping this interface, which is designed for interactive use only.
Data Privacy & Security: All uploaded files and extracted text are automatically deleted immediately after OCR processing is complete. We do not store, archive, or retain any of your data, as detailed in our privacy policy.
EU Data Protection & GDPR Compliance: All OCR servers are located exclusively within
the European Union
. Your data never leaves EU jurisdiction.
Our OCR API is fully GDPR compliant, ensuring the highest standards of data protection and privacy for all users.
