Custom ratio input

Guided crop preview
When ratios differ, the preview highlights the crop frame so you can drag the image and keep the subject centered. No surprise cuts after export.
Aspect locked resizing
Keep the ratio locked while adjusting dimensions to avoid stretching or distortion. This keeps logos, faces, and graphics proportional across exports.

Aspect Ratio Resize FAQ
Helpful answers about ratios, cropping, and exporting.
An aspect ratio is the relationship between width and height, such as 16:9 or 1:1. It defines the shape of an image. Choosing the right ratio helps your image fit layouts for video, web banners, or social media.
If the new ratio differs from the original, cropping is required. The tool shows the crop frame so you can reposition the image. It does not stretch your image unless you manually change dimensions without the ratio locked.
Yes. Choose the custom option and enter a width and height ratio. The tool applies it instantly so you can match exact layout specs, packaging templates, or unique design grids without manual math. Save the ratio and reuse it.
If the ratio matches, no cropping is needed. The image keeps its full frame, and you can simply export in the same dimensions. The preview still lets you confirm framing before delivery and adjust size if needed.
The ratio controls the shape. The pixel dimensions can change depending on how you crop or resize. You can adjust width and height while keeping the ratio locked to maintain the chosen shape and size for each output.
Common choices are 1:1 for square posts, 4:5 for portrait feeds, and 16:9 or 9:16 for video. Check each platform guide, then choose that ratio so your images fit without auto cropping and keep captions visible.
Use the crop preview to drag the image within the frame. Move the subject into the safe area before exporting. Use zoom and drag controls to keep faces, logos, or key details inside the final crop with breathing room.
