We explain how to remove screenshot backgrounds on Mac using Preview’s Instant Alpha, online tools, or LazyScreenshots. Preview works best for solid backgrounds but is manual and can produce rough edges. LazyScreenshots uses local AI: capture with `Cmd+Shift+2`, choose **AI Background Remove**, then press **Enter** to paste the result into an AI tool. PNG preserves transparency, and LazyScreenshots costs $29 one-time.
