Frequently asked questions about resizing
Can I enlarge a small image without loss?
Enlarging an image (upscaling) beyond its native resolution will inevitably lead to a loss of sharpness (blurry or pixelated effect). Our tool is optimized for reducing dimensions (downscaling) while maintaining perfect definition.
Why is my final image distorted?
If your image looks squashed or stretched, you have modified the width and height asymmetrically. Make sure to activate the 'Locked proportions' option (padlock icon) before entering your values.
