How do I resize an image online?

Drop a JPG, PNG, WebP, or similar file on this resizer, set width and height, preview, and download. Nothing is uploaded to RootoverZero for this step.

Can I keep the aspect ratio?

Yes. Lock it unless you intend to change the shape with a crop first.

Does making an image smaller always look worse?

No. A decent shrink from a large original looks sharp at the new size. Enlarging a tiny source looks soft.

What if I need a square?

Crop 1:1 in the [Image Cropper](/tools/image-cropper), then resize that square here if you need exact pixels such as 1080 × 1080.

No. Processing stays in the browser. The image is not sent to RootoverZero to be resized.

What formats can I export?

Use JPG for photographs going to forms, PNG for graphics and transparency, WebP when the destination can open it.
