Frequently Asked Questions
Common questions
16:9, 4:3, 3:2, 1:1, 9:16, and 21:9 presets are available, plus custom ratios.
We use smart center cropping or letterbox padding — never stretching.
The image is resized to a standard resolution fitting the target ratio (e.g., 1920×1080 for 16:9).
Letterbox adds colored bars (usually black or white) to fill the target ratio without cropping.
