Thanks

I know but the PDF version just looks better all round, especially zoomed in. It looks more natural, like looking at the actual piece of paper, and not a pixilated JPEG. I just want to get PDF’s like that if possible, but not if it’s going to be so much bigger files.
What they are on about there about options for compression etc would be very helpful.
I don’t have a clue how it is smoothing things out nicely though. Is the data still JPEG wrapped in a PDF, or was it changed to BMP and wrapped in a PDF?..
That won’t get things smooth like the PDF. And I want each book to end up in one PDF, not a folder full of JPEGs for each book.
I’ve got Libre Office, can’t scan into it though because the drivers are a bit duff, (Canon can't be bothered to update them probably to force people to buy a newer scanner. If I go to scan from Windows 10 it says "You need a WIA driver to use this device. Scanning with the Canon Software works though). I tried importing the JPEGs into Libre Office and Draw. The problem is the images are not perfect a4 size and I would have to move each one in place. 17600 pages is the estimation I need to do. NOT a chance am I moving each one into place manually lol… No batch import in Libre either >.<
Plus still no smoothing that way. Kind of wish I never saw the smoothed version now, because I want it.
Yeah I saw that somewhere else. I didn’t import a PDF though, only JPEGs.
I’ve been trying out a load of JPEG to PDF programs.
Some make uncompressed PDFs but they make big files (Same 4 JPEGS is 97 MB in one of them), and no smoothing like with GIMP's. I haven't found any that just put the JPEGs into the PDF wrapper without messing with the quality at all. Found one that makes minimal difference though.

Quote:“How to make smaller ? Stick with jpeg and for photo quality, 300 ppi but for pure text and line illustrations use a greyscale scan.”
