About Free Online Image Cropper & Resizer
The Free Online Image Cropper & Resizer is a powerful, local-first utility designed to give you complete control over your photo dimensions without compromising your privacy. Developed using HTML5 Canvas APIs, this tool allows you to crop specific regions, rotate images by 90 degrees, flip them horizontally or vertically, and resize them to exact pixel dimensions. You can choose from popular aspect ratio presets (such as 1:1 for social profiles, 16:9 for landscape, and 9:16 for vertical stories) or define custom crops freely. Adjust the quality slider to optimize image file size and export the final result in PNG, JPEG, or WebP formats. Since all operations run locally in your browser, your private photos and sensitive images are never uploaded to any external servers.
