What is OCR?
OCR (Optical Character Recognition) is technology that recognizes text within images and converts it to actual text data. When you scan a document, it becomes an image. OCR reads that image and extracts the text, making it searchable, editable, and copyable.
Output Format Options
Searchable PDF: Creates a PDF where text is searchable and selectable while maintaining the original document appearance. Best for archiving and sharing.
Word Document (DOCX): Exports recognized text to an editable Word document. Perfect for editing, reformatting, or reusing content.
Plain Text (TXT): Extracts pure text without formatting. Useful for data extraction or text analysis.
Why Use OCR?
- Make Scans Searchable: Find specific words or phrases in scanned documents
- Edit Scanned Documents: Convert to Word for editing and reformatting
- Data Extraction: Extract text from invoices, receipts, or forms
