Hello,

I've got an artboard in A4 format with two images at the top.

The images, a JPEG of high resolution 3000 x 1500 for one a TIFF more than 4000px for the other,  placed on the artboard.

When I export for screens, as PDF, the resulting PDF has the images pixelated / compressed / look really bad.

The text is perfectly sharp, everything is sharp but the images are terrible.

This is a link to my screenshot for a better resolution as to see what I'm saying.

I've tried changing the scale in the formats, but when PDF is selected the scale drop down and suffix columns are grayed out.

If I export for Screens as JPEG2000 and select 300ppi for the scale there is no issue.

Here is a screenshot of the result

I could definitely export at Jpeg and then convert to PDF in other application, but is there a way to export a PDF from illustrator without affecting the picture qualities. ?

looking at the PDF settings in Export for Screens (click on the gear icon and pick PDF from the list), it looks like 'Smallest File Size' is selected by default. this sets images to 100 ppi and low quality compression.

pick a different set of PDF options, like High Quality Print for instance, or create your own.

You need to edit the PDF options.

So use File > Save as > PDF

Then in the image compression part of the option, set it to something higher than 72 ppi

Hey Monika.

Ok, I see now.

I was actually trying to save as PDF but by doing, Export As. There is no PDF in the drop-down menu of the format:

But apparently it's possible in Save as. Thanks

I spent half the day trying to fix pixelation of linked images when saving as PDF. Here are a couple extra steps which solved the problem for me: 

In the Compression tab, change all the downsampling settings to "Do Not Downsample." My file sizes are huge, but I don't care. At least the placed images aren't pixelated.

Nice, I didn't realize that gear icon would open up a menu with options.

Indeed, the PDF was set to smallest file size

Thanks.
