What is the Image Resizer?
An image resizer changes the pixel dimensions of a photo so it fits wherever you need it — a profile picture, a website banner, a forum avatar or an upload with size rules. You can type exact dimensions, keep the aspect ratio locked so it does not stretch, or use quick presets. This tool shows the new size before you download and keeps everything in your browser, so your images are never sent anywhere.
How to use the Image Resizer
- Drop in an image or click to choose one.
- Enter the width or height, with aspect lock on to keep proportions.
- Or tap a preset for a common size.
- Download the resized image.

Frequently asked questions
How do I resize without stretching the image?
Keep the aspect-ratio lock on. Change one dimension and the other adjusts automatically to keep the proportions.
Can I make an image larger?
Yes, though enlarging beyond the original size can look soft. Reducing size keeps things crisp.
Which formats are supported?
JPG, PNG and WebP, and you can pick the output format.
Is the image resizer free?
Yes, free with no sign-up.
