Why are my Illustrator images blurry when placed in InDesign?
I am creating simple, clean designs in Illustrator, but when saved as .jpegs or .pngs and placed in an InDesign file at 100% resolution they are blurry as heck.
Converting vector files to bitmaps always degrades quality. And since they are not vector anymore, your title is wrong.
There is no need to convert AI files to bitmaps to place them into InDesign. Place the native AI files instead.
