To compress images in a PDF, extract and compress the images, then replace them in the PDF. You can use tools like Debenu PDF library or QuickPDF. And For different image format such as JPEG, PNG, WEBP, etc you can also try online imagecompressor tool.

QP aren't able to use MRC.
Relevant images for mrc-compression need a special internal data structure.
These special internal data structure isn't taken into account regarding the image handling in the QP-functionalities.

I also staying in hope that we can use:
OriginalImageIDint32 = NewImageIDint32
In such case we should be able to do this without any file/disc operation.

Oh I see.

Maybe we can combine:

http://www.debenu.com/kb/extract-images-from-pdf-files-as-the-appropriate-image-type/
http://www.debenu.com/docs/pdf_library_reference/ReplaceImage.php
http://www.debenu.com/docs/pdf_library_reference/CompressImages.php

I mean extract, + replace with the same data but + CompressImages

I hope CompressImages toogether with ReplaceImage should made the trick..... but I never tested this before.

Thanks so much guys for your help. I will try out the "extract image, compress and replace" algorithm. I'm sure it will work good.
