Loss image quality after editing in Acrobat

[Dariusz5C5F]

Hi,
I was editing pdf in Acrobat (pulling one page out of the entire document and removing short text overlapping the image) and it resulted in a loss of image quality. I searched Acrobat Preferences but did not find. Thanks if anyone knows the solution.

If all your “editing” was done in Acrobat itself, there is nothing in the process of such editing or in the removal of a page that Acrobat would do to change anything whatsoever in terms of the resolution, compression type, compression quality, and/or color of a raster image within the PDF file.

On the other hand, if you opened the PDF file or a page of same in Illustrator to do any editing, all bets are off completely.

Thank you for your response. But I still have my doubts. See pictures below: the first is the image before editing, the second is selecting the text frame, and the last is the image after removing the text frame. When you select a text frame, the image underneath it becomes distorted (see top edge), and the pixels look like a compressed JPEG file.

Regrettably, the screen shots are insufficient for us to really see what has happened or analyze the situation.

Post “before” and “after” PDF files for us to examine and we can try to determine what is actually going on - whether the image has been changed or whether there is some display issue.

Hello,
I send links to separated pages before and after.
