When you have an image file with characters (alphabets), it may be useful to convert the image to a text file. You can do this by using OCR (Optical Character Recognition) software. There are both online OCR and also those you have to download and install into your computer. The former is more convenient.
I have found one particular online OCR which
. supports 46 languages including Chinese, Japanese and Korean
. convert scanned PDF to MS WORD
. extract text from PDF and images (jpg, bmp, tiff, gif) and convert to editable WORD, Excel, Text formats.
Just upload image file from your computer, select language and output format, complete a CAPTCHA to prove you are human, click CONVERT.
It was amazingly accurate with no mistakes that needs to be corrected other than when there are formatting columns, some may be jumbled up and you have to reorganize. I am saving here so I can get back to that online OCR service when needed.
