Why do my pdfs become pixelated when I touch it with mouse in acrobat pro on mac but same pdf is OK in Reader.
If the pdf was created from a Word document there is no problem.
If created from an image and then converted to pdf and OCR performed, the areas where there is blank space are susceptable but not areas of text.
Compression settings for images converted to PDF can be found in the Preferences of Acrobat Pro:
Thank you for your help. I have for a few hours been trying to replicate your screenshot which I cannot do. However I have gotten close as you can see. As well as that I have been experienting ways of creating my pdfs. At the moment they are mostly downloaded jpg files and screenshots which I edit and clean up in Adobe Elements and save as Photoshop pdf. I combine these documents in Acrobat Pro recognise text and save with no compression. It is these pdfs that are causing me concern. Should I be doing this in a different way?
"Not applicable" means that Acrobat always leave JPEGs and JPEG2000s untouched when converted to PDF.
Can you share (part of) this PDF?
"Not applicable" is on your capture, it means that Acrobat will not recompress JPEGs images.
It has nothing to do with headers and/or footers.
Thank you, I now know where the Adobe Acrobat Pro compression settings are. But I still don't know why my pdfs that are created from scanned images pixelate when touched by the cursor but don't when opened by reader.

This will happen if you are in the EDIT tool. Not if you are in the default tool. There is no Edit tool in Reader.
Thank you for the clarification. Because my Reader opens with what looks like the standard Acrobat Pro tools I assumed they were usable. However on trying them I am directed to a seven day trial which must be Acrobat. Now I will have to find out how to hide those tools in Reader. Once again Thank you.
