Merging/Flattening Layers
I want to reduce the file size of a SVG image by making a copy of my Illustrator document and merging all the layers. But how do I do it?
I've checked out several references, but none of them work for me. I can't find a "Flatten Artwork" or "Merge Layers" option. Clicking on layers while holding down the Command or Shift key doesn't work, either. On top of that, I have a lot of layers that I can't click to begin with. There's no way to select them.
Has the process changed in Illustrator 2021?
