Keep the aspect ratio when shape matters
Aspect ratio is the relationship between width and height. If you change one dimension without changing the other proportionally, the image can look stretched or squeezed.
ConvertZiva's Image Resizer keeps aspect ratio locked by default so common resizing tasks preserve the original shape unless you intentionally unlock it.
Downscaling versus upscaling
Downscaling removes pixels and usually works well when you need a smaller image for web pages, forms, or messages. Upscaling adds pixels and can make soft or blurry details more noticeable.
A practical rule: resize to the largest size you actually need, then compress if the file is still too large.
Useful examples
For a profile image, you might resize a large photo to a square dimension after cropping elsewhere. For a website image, you might reduce a 4000 pixel-wide file to 1600 pixels wide while keeping the original ratio.
ConvertZiva's image tools currently support up to 12 JPG, PNG, or WebP images, with each image up to 10 MB.

FAQ
Why does my image look stretched?
The width and height were probably changed without preserving the original aspect ratio.
Does resizing improve image quality?
No. Resizing can make dimensions more useful, but it cannot recreate detail that was not in the original image.
