How to convert scanned TIFF documents to text files
When a paper document is scanned, it is usually saved as a TIFF file on the computer. In order to convert this file into a text file that can be searched and edited, you need to have OCR software on your computer. OCR, or optical character recognition, uses the optical properties of the text characters in a scanned document to identify the characters, which ultimately makes all of the text in the scanned document available to the computer.
Features of text recognition
OCR software is able to recognize printed text with high accuracy. Though accuracy ratings vary from one product to another, in general OCR is quite reliable and allows you to avoid retyping information unnecessarily. Some OCR tools have batch processing capabilities, meaning that they can process entire folders in a single step. This is important in industrial use, where large groups of documents may need to be processed at once.
Best TIFF to text software
Instead of limiting your search to programs that can OCR TIFF files directly, you may want to consider the possibility of using PDF OCR, converting your files into PDF before OCRing them. PDF is a more convenient format in general, and is known for its portability and lossless compression. CVISION software can convert TIFF files into PDF, compress them, and OCR them, all in a single step. Download the free trial version to check it out.
