interactive pdf causing pixelation

[rosemary5CFA]

Hi there, im creating interactive pdfs and they are exporting to a very low resolution. I have set dpi to 300 and have slected maximum quality. 

First photo attached is from indeisgn and the second is the file exported to interactive pdf 

Can anyone help?

A couple things:

If those are placed raster images, it is their actual resolution that's exporting, not the 300 ppi set in the Interactive PDF Export dialog. That is, export doesn't up-sample them.

If they are very small, and screen-resolution, the result isn't all that surprising. It takes a lot of pixels to render clean edges on a circle.

If better graphics aren't available, one fix I'd consider trying is just drawing an InDesign-native (vector) black-filled circle to position behind each icon to "supplement" its edges. (The white symbol on each icon looks satisfactory to me.)
