How OCR Technology Works

Our OCR (Optical Character Recognition) technology analyzes the scanned image, identifies text characters, and converts them into editable, searchable text. This is especially useful for extracting information from receipts, business cards, contracts, and forms. The extracted text can be copied, edited, or saved as a text file for further use.

Privacy & Security

Your scanned documents are never stored permanently. Images are automatically deleted from our servers within 60 minutes of processing. We do not access, view, or analyze your document content beyond the scanning and OCR operations. No personal information is collected or required to use this tool.
