FAQ

Can I lock the aspect ratio?

Yes. With aspect-ratio lock enabled, changing one dimension automatically calculates the other.

What is the difference between contain, cover, and stretch?

Contain keeps the full image and may add padding, cover fills the target size by cropping edges, and stretch forces the image into the exact dimensions.

Does batch resizing work?

Yes. All selected images are processed with the same dimension settings.

Are images uploaded to a server?

No. Resizing runs locally in your browser.
