Frequently asked questions
What is the difference between resizing and changing aspect ratio?
Resizing scales the full image. Changing aspect ratio adjusts the canvas shape, potentially cropping or padding.
Do composition tools upload my images?
No. All geometry changes run locally in your browser.
Can I use custom aspect ratios?
Yes. Enter any width and height values to create a custom ratio.
