hi thx for share.I have checked that.it works but the facilities are not complete enough .Once I used Adobe Acrobat. but it becomes more and more expensive for public users who haven;t got many pdf files to process. here I would like to share with you the tool Im using now ,it is denefinitly easier to handle than Adobe Pro.This pdf to Jpg convert will enable you to do a wide variety of ways to do batch conversion of your pdf files in just a few clicks.If you donnot have a good choice.You can download the free trail package and have a try.
