Will resizing reduce image quality?

Making images smaller typically maintains good quality. Making images larger may reduce sharpness. Use high-quality originals when possible.

What dimensions should I use for web?

Can I maintain aspect ratio?

Yes, you can maintain aspect ratio to prevent distortion. The tool will calculate one dimension based on the other.

Is my image data secure?

Can I resize multiple images?
