I scanned a document and would like to crop out around half of the image.
I can crop using Preview or using Adobe Acrobat Pro. But neither program permanently crops the file. The file size never decreases.
I tried using "Remove Hidden Information" on Adobe Acrobat Pro which was able to permanently crop the file. After the process completed, I clicked Save which opened a new Save As prompt. So, I re-saved the document, but the file size grew tenfold. No idea why.
I tried exporting to Optimized PDF on Adobe Acrobat Pro and the PDF was still not permanently cropped.
I tried exporting to Reduced Size PDF on Adobe Acrobat Pro and the PDF was permanently cropped, but the image quality was decreased.
I tried exporting to PostScript on Adobe Acrobat Pro, and from that, creating a new PDF. The PDF was permanently cropped, but the image quality significantly decreased.
I tried creating a custom Preflight Fixup in Adobe Acrobat Pro, using "Set page geometry boxes". The resulting PDF was not permanently cropped.
Are there seriously no options to remove the cropped area without exporting the file as TIFF and importing the TIFF files to create a new PDF file or ->Print->Save As PDF? I don't want to do these because the image quality will decrease.
I'm on OS X but I also have a Windows machine I can use.
