After trying out various converters, I finally found a freeware converter that offers you a choice on whether to convert a PDF document to a Word file with or without text boxes, and with or without line breaks in the output. So here's one that's free and with no nags, and no ads with a cryptic name: Some PDF to Word Converter.
It also offers batch processing and other customizability such as selecting the number of pages to convert, deleting graphics, pictures, and so on. Although online converters exist that do a fairly good job, I would rather handle sensitive documents on my desktop rather than uploading them for online conversion. Here are the options this utility offers (see image):
The application works on Windows NT/2000/XP/2003/Vista. This one is a keeper. I am, however, yet to find a similar one that has like features and works with Japanese PDF documents; would any of our Japanese readers who frequently scan Vector, Mado no Mori or similar Japanese websites like to add some information on Japanese freeware to convert Japanese PDF documents to Word documents? This is a long-felt need for JE translators.
Your results may vary with Some PDF to Word Converter – try out conversions with and without line breaks too. I had good results with a PDF document in English without fancy formatting.
Incidentally, the downloads page on the same site has other converters also to convert PDF to html, txt and so on; and all free, of course.
