Change a picture to 1:1, 4:5, 9:16, 16:9 or any ratio by cropping it or fitting it with colour, blurred or transparent borders
Add the picture to the Image Aspect Ratio Changer, pick a ratio such as 1:1, 4:5, 9:16 or 16:9, and choose Crop (cut the edges, slide to choose what stays) or Fit (keep the whole picture and fill the bands with a colour, a blurred copy or transparency). Save it; nothing is stretched or uploaded.
The proportion between an image's width and height, written width:height. 16:9 is widescreen, 9:16 a vertical phone screen, 1:1 a square and 4:5 Instagram's portrait post.

Result: The picture in the new aspect ratio
Fit keeps the whole picture and adds bands to reach the new shape. Fill them with any colour, a blurred copy of the picture (popular for Stories and Reels) or transparency (PNG or WebP).
Crop cuts the edges and Fit adds bands; neither stretches the picture, so faces and objects keep their shape.
Square posts are 1:1, portrait posts 4:5 (1080 × 1350 px), and Stories and Reels 9:16 (1080 × 1920 px). Choose the ratio and the 1080 px width.
Use the crop position slider to move the frame left or right (or up and down) over the picture; the preview updates as you move it.
It is changed in your browser. Like any canvas edit, the camera data (EXIF) is not copied to the new file.
Add several pictures; they all get the same ratio and settings and download as a ZIP.
Crop cuts out the largest area of the new shape that fits inside the picture, at the position you choose. Fit makes the smallest canvas of the new shape that holds the whole picture, centres it, and fills the rest with a colour, a blurred copy of the picture or transparency.
By default the result keeps the picture's own resolution. Width presets (1080, 1200, 1920 px) scale it down to that width; a smaller picture is never enlarged. JPG and WebP are saved at 92% quality, PNG losslessly.
1:1 and 4:5 for Instagram posts, 9:16 for Stories, Reels, TikTok and YouTube Shorts, 16:9 for YouTube and slides, 1.91:1 for link previews, 2:1 for banners and X cards, 3:2 for camera photos, and 4:3 for classic screens.
The picture is processed in the browser and not uploaded; EXIF camera data is not copied into the new file.

| Adds borders | No | Yes: colour, blur or transparent |
| Best for | Photos with space around the subject | Group photos, text, screenshots |

Neither method stretches the picture.
