A 4K screenshot at full resolution is usually 3-5MB — resize to 1920px wide first, then compress. The visual difference is negligible on most screens.
For screenshots with mostly solid colors or UI panels, PNG with reduced color depth can be surprisingly small — test PNG output before switching to JPEG.
Use the quality slider to preview the trade-off: most screenshots look identical down to 70-80% quality while cutting file size by 50% or more.
