Everything runs locally in your browser — nothing is uploaded.
How to use
Upload an image, enter the width and height in pixels (keep the aspect-ratio lock on to avoid distortion), pick an output format, then download the resized image.
Frequently asked questions
Is the image resizer free?
Yes, free with no limits or signup.
Are my images uploaded?
No. Resizing happens in your browser; your images never leave your device.
Will resizing make my image blurry?
Shrinking is safe. Enlarging beyond the original size can look soft — the tool warns you when upscaling.
