Choosing the right image dimensions
For website images, use the dimensions your layout actually needs instead of keeping a very large original. For profile images, banners and forms, exact pixel dimensions can make cropping and placement easier.
Changing dimensions can affect image sharpness and file size. Check the result at the size where it will actually be displayed.
FAQ
Image Resizer questions
Can I resize images without uploading them to a server?
Yes. This tool uses browser image APIs, so the resize operation is designed to happen on your device.
Which image formats are supported?
The interface accepts JPG, PNG and WebP files supported by modern browsers.
Why should I keep aspect ratio enabled?
Keeping the aspect ratio helps prevent the image from looking stretched or squashed when only one dimension needs to change.
