lassocrop

LassoCrop is a free, browser-based lasso crop tool that lets users cut out any shape from an image and export it as a transparent PNG. It combines manual selection modes—Rectangle, Polygon, and Freehand—with optional AI-assisted subject detection, allowing users to isolate exact content such as products, people, logos, or interface elements. The tool addresses the problem where a standard rectangular crop retains too much background or where users need to define the result themselves, providing a direct path from upload to export without sign-up or installation.
