QuoteInstalled the program, wow, this is nice program, very handy for website makers. Thanks a lot! - By Bart Vreeswijk
QuoteVery useful for me, I often have to convert pdf drawings into jpg so I can manipulate them in photoshop equivalent or import into CAD program. Previously done via serif pageplus or paperport but this is simpler. Easy install into Windows 7 64 laptop and worked fine when tested. Will keep and use, thank you. - By bungalowbuild
QuoteInstalled and registered the program on Win 10 Pro 64bit desktop. Registration and etc. was a breeze. The program works as stated and I will keep it until I have another that is better. Thank you TriSun! - By Rick Martin
QuoteWhy convert a pdf to jpg? Microsoft Publisher doesn’t import pdf’s. Just one thought. Someone sends me a pdf, I can convert it to jpg and import it. Copy/paste isn’t so good of an option. - By RW
QuoteI am very pleased with the software. There is not a lot of software that I like and find a waste of time, but am impressed with your sofyware. - By James A Weir (GB)
