Frequently Asked Questions

What is the difference between contain and cover?

Contain keeps the whole image visible with padding. Cover fills the target box but can crop the edges.

What happens if I enter only the width?

Width-only mode keeps the original ratio and calculates height automatically.

Can I keep the original aspect ratio?

Yes. Use contain, width-only, or height-only mode to preserve the ratio.

JPG, PNG, and WebP input are supported. Output formats depend on the tool purpose.

HEIC, RAW, SVG editing, animated GIF preservation, and AI background removal are not currently supported.
