Frequently Asked Questions

What aspect ratio presets are available?
You can choose from 16:9, 4:3, 1:1 (square), 9:16 (portrait), 3:2, 21:9 (ultrawide), circle, and more. You can also type in any custom ratio you need.
What happens if the crop area extends outside the image?
Enable the outside-image option when you need the selected ratio without cutting away more of the photo. The added area uses your chosen background color, or transparency when the selected output format supports it. The original pixels are not stretched.
Can I set a custom aspect ratio?
Yes. Enter any width-to-height ratio you need in the custom input. The tool applies it instantly so you can preview the result before downloading.
Can I choose the background outside the original image?
Yes. Choose a solid background color, or use transparency with PNG, WebP, AVIF or GIF. This setting is used wherever an allowed crop extends beyond the original image.
What output formats are supported?
You can save as PNG, JPG, WebP, AVIF, and other common formats. Pick the one that fits your needs from the format selector.
