thanks there is only one downside... JPEG takes more space than PDF i had about 20 gig of pdf converted to 80 gig of pngs (1 picture per page) i then converted those pngs to JPEG at 95% quality and it was about 60 gig. Am currently redoing them at 85% quality to see how big it is then. Space is not an issue for me though but just interested in knowing. Thats the only downside but for the rest i'm happy with it and i can use it on my raspberry pi also (also got a disk there)EDIT: same manuals at 85% jpeg quality is only 36 gigabyte so going to use 85% almost halved in size compared to 95% quality
