Selecting an area

Ranjesha's suggestion to disable anti-aliasing should fix the issue.

In Preferences > Cursors, choosing Precise will let you more exactly view the area being selected.

Hi @toddt51923266 

We understand the situation when there's an interruption in workflow. We're here to help! 

Which version of Photoshop are you using? Does this happen with all images?

Before selecting, you can try disabling anti-aliasing in the options bar at the top of the screen. Look for the " Anti-alias " checkbox and uncheck it before selecting. This might reduce the likelihood of extra pixels being copied. When making your selection, try to ensure that the edges align precisely with the pixels you want to copy. This can sometimes prevent the anti-aliasing from adding extra pixels outside the selection.

If you're using the Marquee tool and still encountering issues, consider the "Magnetic Lasso" tool instead. This tool can help you create a more precise selection by automatically snapping to the edges of objects.

We're here to help, just need some info.

Best,
