In short: Cropping an image cuts away its outer parts to keep a chosen rectangle, either freely or at a fixed aspect ratio such as 1:1 or 16:9.
About Crop Image
Cropping removes distractions, straightens the focus on your subject, and fits an image to the shape a platform expects: square for profile pictures, 4:5 for portrait social posts, 16:9 for video thumbnails and slides, 1.91:1 for link previews.
Drag on the image to move the crop box and use the corner handle to resize it. With a ratio locked, the box keeps its proportions. For precise work, type exact X, Y, width and height values in pixels of the original image. The crop is taken from the full-resolution original, not from the scaled-down preview.
How to use Crop Image
- Choose or drop an image.
- Pick an aspect ratio, or leave it on Free.
- Drag the box to position it and drag the round handle to resize, or type exact pixel values.
- Choose the output format and press Crop and download.
Examples
Select 1:1, center the box on the face and download as PNG for a profile picture.
Select 1.91:1 to cut a 1200 × 628 area that social networks display without further cropping.
Frequently asked questions
Does cropping reduce quality?
No. Cropped pixels are copied exactly from the original. Only JPG or WebP encoding is lossy; choose PNG for a perfect copy.
Can I crop on a phone?
Yes. Drag with one finger to move the box and drag the handle to resize it.
How do I crop to an exact pixel size?
Type the width and height in the selection fields, then resize the result with the Image Resizer if you also need to scale it.
Are my images uploaded?
No. Cropping happens in your browser. You can check this yourself: open your browser’s developer tools, switch to the Network tab and use the tool — no request carries your input.
