Image Resizer
Resize an image to an exact width and height or by percentage.
Resize Image
The Image Resizer changes an image's dimensions to a specific width and height, or by a percentage of the original size. It is free and requires no sign-up. Website owners fitting images to a layout, sellers meeting a marketplace's size requirements, and anyone shrinking a photo before emailing it will find this tool straightforward to use.
What does an image resizer do?
Resizing scales an image's pixel dimensions up or down while keeping all of the original content visible, unlike cropping which removes parts of the picture. You can lock the aspect ratio so the image doesn't look stretched, or set width and height independently if you need an exact, non-proportional size. Many platforms specify pixel dimensions for banners, thumbnails, or profile photos, and resizing is the direct way to hit those exact numbers.

Frequently asked questions
Is the Image Resizer free?
Yes, resizing images is free and does not require sign-up. You can resize as many images as you need.
Can I resize without distorting the image?
Yes, locking the aspect ratio keeps width and height proportional so the image doesn't look stretched or squeezed. Unlocking it lets you set both dimensions independently if you need an exact, non-proportional size.
What's the difference between resizing and cropping?
Resizing scales the whole image to new dimensions, while cropping cuts away part of the image to change its shape or focus. Use resizing when you want to keep everything visible at a different size.
Does resizing reduce file size too?
Smaller pixel dimensions generally result in a smaller file size, since there is less pixel data to store. For further size reduction beyond dimension changes, pairing this with a compressor helps.
