As you drag, you may notice that the artwork is snapping to the pixel grid.Aligning existing artwork to the pixel grid
You can also align existing artwork to the pixel grid in several ways, which is what you will do
in this section.
Press Command and - (macOS) or Ctrl and - (Windows) once to zoom out.
Select the Selection tool ( ), and click to select the blue stroked rectangle surrounding the
rectangle you drew.
Click the Align To Pixel Grid button in the Properties panel to the right (or choose Object >
Make Pixel Perfect).
Note
In this instance, the Align To Pixel Grid button in the Properties panel and the Object >
Make Pixel Perfect command will do the same thing.The rectangle was created when View > Snap To Pixel wasn’t selected. After you aligned the
rectangle to the pixel grid, the horizontal and vertical straight edges were snapped to the closest
pixel grid lines. Live Shapes and Live Corners are preserved when this is done.Objects that you pixel-align that have no straight vertical or horizontal segments are not
modified to align to the pixel grid. For example, because a rotated rectangle does not have
straight vertical or horizontal segments, it is not nudged to produce crisp paths when the pixel-
aligned property is set for it.- Click to select the blue “V” to the left of the button. You may need to scroll to the left. Choose
Object > Make Pixel Perfect.
You will see a message in the Document window, “Selection Contains Art That Cannot Be
Made Pixel Perfect.” In this case, this means there are no vertical or horizontal straight edges
to align.
