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's the difference between crop, fit, and stretch?
Crop to fill cuts off edges to fill the new ratio exactly. Fit with padding keeps the entire image visible and adds a background color to fill the extra space. Stretch distorts the image to match — useful only in specific cases.
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 change the background color for padded areas?
Yes. When using the Fit (pad) mode, a color picker appears so you can set any background color — white, black, transparent, or any custom color.
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.
