Fast Answer: Resizing Without Distortion
When you upload an oversized 4000x3000 photo to a website, the browser has to spend CPU cycles downscaling it every time a visitor views your page. Furthermore, forcing arbitrary width and height tags often stretches or squashes the image.
The Image Resizer Tool on Tools24Now lets you lock the aspect ratio and downsample high-res imagery to exact target dimensions in your browser.
