Crop an image around what matters
Cropping to a square or a 16:9 banner usually means chopping equal amounts off each side and hoping the important part survives. This tool measures where the visual detail actually sits - edges, texture and contrast - and picks the framing that keeps most of it. Choose one of five aspect ratios, compare it with the original, and use the regular crop tool if you want a different shape or want to place the rectangle yourself. Everything runs on your device.
How to crop an image around what matters
- Drop an image onto the upload area, or choose a file from your device.
- Pick one of the five aspect ratios: square, 4:5, 16:9, 9:16 or 3:2.
- Review the suggested framing against the original.
- Download the crop, or switch ratios to compare.
Supported formats
This tool accepts JPG, PNG, WebP, GIF, BMP and AVIF files. Everything is decoded by your own browser, so the formats available depend on what your browser can open - which for HEIC in particular varies between Safari and other browsers.
Frequently asked questions
How does it decide where to crop?
It builds a map of where visual detail sits by measuring brightness gradients and local contrast, then tests thousands of candidate rectangles and keeps the one with the densest detail. There is no object detection and no face recognition involved, so it will not tell you it found a person - it tells you where the detail is, which is what it actually measured.
Does this use AI?
No, and that is deliberate. A neural model would mean a multi-megabyte download and a slower result for a job that arithmetic already does well. The analysis is a few milliseconds of maths on a small copy of your image, so there is nothing to download and nothing to wait for.
Is my image uploaded?
No. The analysis and the crop both happen inside your browser, and a content security policy the browser enforces stops this page sending anything to another domain. You can watch the network panel while you use it and see that no request carries your image.
What if I disagree with the crop?
Switch to a different aspect ratio to see other framings, or use the regular crop tool to place the rectangle yourself. The suggestion is a starting point, not a verdict, and the tool tells you how much of the image's detail a given framing actually keeps so you can judge it.
Why did it choose an odd framing for my photo?
Usually because the detail is spread evenly, which happens with landscapes, patterns and busy scenes. When no single region stands out the tool says so rather than pretending to be confident, and that is the moment to crop it by hand.
Does it lose quality?
Cropping removes pixels but does not re-compress the ones it keeps any more than saving the file normally would. The output keeps the source resolution within the cropped area, and the format is preserved where your browser can encode it.
