Splitting 30 page 15.9Mb pdf into 30 separate pdfs. Why are the resultant files each 15.9Mb?

Hi

 

As the heading says! Why are the resultant files each 15.9Mb, rather than say .53Mb each. Sloppy programming?

 

Anyone know how to solve this? I've looked at Reduce file size. AAPro forces me to have at least 1 file open for the Reduce File Size option to be available under File. I open a random file, select Reduce File Size, select the file I want to reduce, it says Done and the file size has reduced to 14.3Mb. When I open it, it has only the 1st page.

 

Which idiot designed this? I despair!

 

The content of the pdf is individual music scores, no more than 10 rows per page.

 

TIA.

 

Doug

    Re the first issue: Imagine the file uses a custom-made font that's very heavy, and that's fully embedded in it. When you split the pages they still need to have a copy of that font, so instead of one file with a 15MB font for all 30 pages you end up with 30 files, each one with a unique 15MB copy of it. The same can happen with other things, such as background images, etc.

    Probably the bulk of the size comes from something that is kept in all the files. Likely if it's exported from Adobe Illustrator for example. On the one page thing: surely your files after splitting are just one page? Or are you saving over the original? Reduce File Size includes a save.
