How to resize an image online
Upload an image, enter the width or height you need, and click resize. Keep the aspect-ratio lock on to avoid distortion, or unlock it to stretch to precise dimensions. Preview the result, then download.
Resizing is handy for fitting profile pictures, thumbnails, social banners, and web images to exact size requirements. Everything runs locally in your browser, so your images stay private.
Frequently asked questions
Can I keep the aspect ratio?
Yes. With the lock enabled, changing the width updates the height automatically (and vice versa) so your image never looks stretched. Unlock it if you want to set width and height independently.
Will resizing reduce quality?
Shrinking an image keeps it sharp. Enlarging beyond the original dimensions can look soft, since there's no extra detail to add — resizing can't create pixels that weren't there.
What formats are supported?
You can resize PNG, JPG, WebP, and other common web image formats. The output keeps the original format where possible.
Are my images uploaded anywhere?
No. Resizing happens locally in your browser using the HTML canvas — your images never leave your device.
