OCR stands for Optical Character Recognition — a technology that reads text from images and scanned documents and converts it into actual, selectable, searchable text. When you scan a physical document, photograph a receipt, or receive a PDF that was created from a scanner, the result is an image file that looks like text but contains no actual text data. You cannot search it, copy from it, or edit it.
The PDFSass OCR PDF tool solves this problem. Upload your scanned PDF or image-based document and OCR technology will analyse each page, recognise the characters, and return a new PDF or text output where every word is fully searchable and selectable. This is essential for filing documents in digital archives, making contracts searchable, or extracting data from old records.
