Resize image to 1200x400
Drop one or more images into the dropzone to instantly resize them to a 1200×400 compact banner size. The tool uses a cover fit approach to fill the wide, modular frame without stretching or squishing your source material. If your original image doesn’t match the 3:1 aspect ratio perfectly, the edges will be cropped evenly to lock onto the 1200x400 dimensions.
Automatic cover cropping
There are no complex settings or crop boxes to configure. The layout strictly enforces the target dimensions, running a fast local algorithm to anchor your image centrally and trim the overflow. This guarantees every exported file is ready to use for UI sections, feature banners, or embedded website visuals.
Batch processing
If you need to resize images for website sections in bulk, you can queue multiple files at once. Each image will be processed individually on your device. Once complete, click “Download all as ZIP” to grab all your formatted 1200x400 images in a single archive. All image processing stays completely within your browser.
