change dimensions
The Image Resizer changes an image's width and height to dimensions you specify, with an option to lock the aspect ratio so the image doesn't stretch or distort. It's a quick fix for images that need to fit a specific size requirement.
Meeting a platform's exact image size requirement, like a profile picture or banner.
Shrinking a large photo down to a size that's easier to embed in a document or email.
Preparing a batch of product images to a consistent, uniform size.
Scaling an image up slightly for a print or display requirement.
Not if you keep aspect ratio locked — the tool scales width and height proportionally so the image keeps its original shape.
Enlarging an image stretches its existing pixel data, so significant upscaling can look softer; small increases are usually fine.
You can enter any pixel dimensions; very large targets are limited only by your browser's available memory.
