Whether you need half-size images or an exact banner width, open our Image Resizer to change dimensions without installing design software.
Percentage resizing for quick scaling
Percentage is the fastest choice when proportions should remain unchanged. A 50 percent setting reduces both width and height by half, which works well for preparing a lighter copy of a large original. It also avoids manual calculations when several images need the same scale.
Pixel dimensions for a specific placement
Use exact pixels when an image must fit a CMS hero area, a marketplace requirement, an email template, or a social profile frame. Keep aspect ratio enabled when the final image does not need a prescribed shape; that prevents people and products from looking stretched.
Check the destination, not just the file
The best dimensions depend on where the image will appear. A file intended for a wide desktop banner should not use the same crop or width as a square mobile card. Resize a copy, preserve the original, and view the output in the layout where it will be used.
