Change an image's aspect ratio
Reshape any picture to a square, story, widescreen or custom ratio — by cropping the edges or padding with a background colour.
Drop a photo to change its aspect ratio
Crop or pad any image to 1:1, 4:5, 16:9 and more — processed in your browser.
Crop or pad — which should you pick?
Every platform wants a different shape: 1:1 for a profile picture, 4:5 for an Instagram post, 9:16 for a story or reel, 16:9 for YouTube and presentations. Getting the ratio wrong means the platform crops it for you, often badly.
Cropping fills the frame completely by trimming the edges — best when the subject is centred. Padding keeps the whole picture and fills the leftover space with a colour you choose — best when nothing can be cut off, like product shots or artwork.

Frequently asked questions
How do I change a photo to 1:1 or 16:9?
Drop the photo above and tap the 1:1 or 16:9 preset. Choose Crop to fill the frame or Pad to keep the whole image with a coloured background, then download.
Will changing the ratio reduce quality?
No upscaling is applied — the tool works from your original resolution and only trims or pads, so the picture stays as sharp as the source.
Can I use a custom aspect ratio?
Yes. Enter any two numbers, for example 21:9 or 5:7, and the preview updates instantly.
