[Image-SIG] PIL - problem with crop()

I have a bunch of .jpg images of 2866 x 4047. When I
right-click on them and use the "Convert to Adobe PDF" option from
Acrobat, an Acrobat window opens showing the document with great
quality and zoom of 121% - and if I zoom down to 100%, it looks like
the original quality.
However, I would like to crop the bottom
of all pages before conveting to PDF, so i get back to the original and
use "im.crop((0, 0, 2866, 3760))".
Now, if I use the method
above to convert to PDF, the PDF will open at 21,9% - the image got
much bigger! - and if I zoom up to 100%, it gets awful. I understand
PIl is not only cropping the image, but also affecting its quality.
Any suggestions on how to avoid that?
Here is the complete script:
import os, Image
preCropFolder = "C:\\PDF\\preCropFolder"
postCropFolder = "C:\\PDF\\postCropFolder"
inputImages = os.listdir(preCropFolder)
for file in inputImages:
eachImage = preCropFolder + "\\" + file
im = Image.open(eachImage)
im = im.crop((0, 0, 2866, 3760)) # original is 2866 x 4047
eachImage = postCropFolder + "\\" + file
