Question

Illustrator PDF scales up all images

Hi. I really wish to know if there's any way to configure illustrator PDF file to embed images as they are without scaling them up or changing their format. I got many PNG and JPEG files of width 1920 pixels and they're about 50 to 75 KB each (some JPEG about 150 KB). But when saving them as PDF files they become 9 MB. Is there any way not to scale them up or to embed them as they are? Thanks in advance.

Not sure what you are meaning by "scale them up" but I certainly understand that the way Illy saves a pdf with images is not what I often expect. I just exported a file from InDesign to pdf (Press Quality) and get a 2.3M file (it contains a 60x28 72dpi image that has been cropped and scaled to give and effective dpi of 40- not great but it's going on Amormesh so ok-ish). I'd already quit out of InDesign (I rarely use it) forgot there was ONE small text change (one letter typo!), opened the pdf in Illy, saved out and file is now 40M (Illustrator Default). I went back to the original 2.3M file made the change and saved as Press Quality pdf - 22M. I went back to InDesign, made the change there, saved as Press Quality get the same 2.3M pdf...

Check the compression settings in the pdf settings for downsampling and compression type.

I don't think you can just embed the images as they are compressed.

In fact I have an alternative. But it is strange that Adobe doesn't give the option not to compress. In fact if you downsample the compression ratio to 72 dpi, you still don't save a lot in size. My alternative that I have been doing is through LaTex code. The LaTex app generats the PDF without modifying any image. I wish Adobe does the same thing.

I think it would be a good option not to recompress images if they are unchanged.

Interesting, so the LaTex app can take an Illustrator file and generate a PDF from it?
