Reducing file size caused by ultra high resolutions

Post by samurai »

I have a pdf file with size of 1,4 Gb. In pdf-xchange I can see the resolution of the scanned jpg's is like 3000 x 5000. Much too big for my screen.

I could not find a feature to reduce size/resolution of pages. So I exported 5 files with 72 dpi, and got 5 files of around 100 Kb.

When I make a new pdf with the 5 files of total 500 Kb, the resulting pdf is 4,5 Mb?? My tryout to reduce the size failed, why is it still so big?

Can somebody help me with reducing this filesize of 1,4 Gb?

Hello samurai,

And welcome to our forums! If you have our Printing drivers as well - try directly "printing" your document to pdf again - without first exporting the pages as images - and see if that will produce a smaller file.

As for conversing 500 KB of images to a 4.5 MB PDF - please check the image compression settings you are using at creation time, and also have in mind that there is some inevitable overhead as a PDF file contains more than just the images - so you won't be able to get a PDF file exactly matching the size of your images.

Best,
Stefan
