How to split or cut raster image object that was placed in Adobe Illustrator?

The Knife Tool doesn't work on raster images.

  • I'm afraid we may need a bit more to go on. There's the Knife Tool, The Scissors Tool, Pathfinder, Pen Tool, Masks.. so many things. Which one to use depends upon what specifically you need to do.

    You cannot slice images. But you can use clipping masks to fake the cuts.

  • @LeoNas you can slice images in the general sense of "slice". You can't use the Knife tool on raster images though. :)

Images can't be cut using standard tools in Illustrator because it is a Vector editing software. (Your images are raster)

Your options are (ordered from most ideal to least)

  • Use a clipping masks.

  • Use Photoshop (or other Raster editing software)

  • Use autotrace to make the image Vector and then you can cut it how you like (problem is, you'll have many paths)
