I want to know how to edit jpg file which is in text format... if I convert it into word file than how can I edit that word file... let me know the answer..

I'm sorry but I didn't got your question. You have an image of a word file, am I rite? Is this your question. Then use Abby fine reader which can convert image files into editable word documents. For more information visit ABBYY OCR SDK for integrating intelligent and accurate OCR, ICR, OMR, barcode recognition and PDF conversion technologies

Hope that works
