Image Resizer

Resize Images Online — Free

Resize any image to exact pixel dimensions, or scale it down by percentage, without installing an editor or losing more quality than necessary.

How to Resize an Image

Upload your image, then enter the width and height you need — or pick a percentage to scale it down by. A live preview shows the result at the new size, and clicking "Resize" downloads it immediately.

Keeping the Right Proportions

Locking the aspect ratio means changing one dimension automatically adjusts the other, so your image never ends up stretched or squashed. Turning that off gives you full control over width and height independently — useful when a specific size is required regardless of the original shape, like a banner ad slot or a profile picture with fixed dimensions.

Good Uses for This Tool

Shrinking a large photo down to a size that's actually usable on a website, meeting a platform's exact image dimension requirements, preparing a batch of images to a consistent size, or resizing a photo before attaching it somewhere with a small upload size limit.

Is It Actually Private?

Yes. The resizing happens entirely in your browser using canvas — your image is never uploaded anywhere.
