About Image Cropper
Cropping is a fundamental photo-editing operation: trim unwanted edges, adjust composition, or fit a fixed size or ratio. This tool provides a visual drag-to-select cropping editor in your browser, supporting free crop and locked ratios like 1:1, 16:9 and 4:3, with PNG, JPEG or WebP export. Everything is processed locally - images are never uploaded.
