Quick answer

Resize image to 1584 × 396 directly in your browser. Upload an image, use the prefilled settings, process it locally, and download the result.

How it works

1584 × 396 is a 4:1 landscape frame (about 0.6 megapixels), commonly used for thumbnails, banners, slides, and video covers. The resizer below is preset to these exact pixels, so you can drop in any photo and get a correctly sized file without opening a heavy image editor.

Upload your image.
ResizeWizard applies the 1584 × 396 pixel preset.
Choose an output format and process the file.
Download the resized image.

Tips for the best result

Your source image should ideally have a 4:1 aspect ratio; if it does not, expect some cropping to reach 1584 × 396 cleanly.
Keep important details away from the edges so nothing critical is lost in the 4:1 crop.
Resize to these pixels first, then compress to a KB limit if the destination also caps file size.

Common mistakes to avoid

Do not edit the only copy of your image. Keep the original before using this page.
Do not judge the result by file size alone. Open the downloaded image and check important details.
Do not stretch the image to 1584 × 396 if the aspect ratio does not match. Crop or contain it instead.

Example workflows
