Good to know

Turn off the lock to set width and height separately and intentionally change the ratio. Downsizing oversized images also improves load speed and mobile data use.

Frequently asked questions

How do I avoid distortion?

Enable aspect-ratio lock and enter only one side; the ratio adjusts automatically.

Can I enlarge?

You can, but going above the original may look soft.

Can I match many images to one size?

Enter the same dimensions for each to standardize them.
