About Smart Crop

The HAXTANX Smart Crop tool automatically analyzes your photos in the browser to identify focal subjects, faces, and key visual areas. It recommends the best crop rectangle for any standard or custom aspect ratio—ensuring key subjects are never clipped—while giving you complete interactive control to fine-tune framing before exporting.
