Image Cropper changes the picture you already have
Cut a center crop when you need a tighter frame and do not have an editor open.
A percentage is trimmed evenly from the edges.
What Image Cropper cannot recover
This is a center crop, not a freehand crop. If the subject is in a corner, crop in another app first.
Why Image Cropper is its own job
Image Cropper sits on this site because Image and Image are not interchangeable, even when they look similar in a file list. Cut a center crop when you need a tighter frame and do not have an editor open. Resize, crop, rotate, compress, or change a photo when the next form has rules. Resize, crop, rotate, compress, or change a photo when the next form has rules.

The Image file you already have
Image tools redraw the picture in your browser. They do not upload the file. These tools do not recover detail the camera never captured. Upscale and HD modes enlarge pixels. They are not AI reconstruction.
Keep the original photo.
What a Image result is for
Image Cropper keeps the format family as Image and still changes the file you can use. Resize, crop, rotate, compress, or change a photo when the next form has rules. The original pixels are what you have to work with. The edit is local.
Compress from the best original, once. A second lossy save softens detail that is already gone.
How to tell that Image Cropper worked
Image Cropper is worth using only when Image is what the next step actually named. Cut a center crop when you need a tighter frame and do not have an editor open. What you get from Image Cropper: A percentage is trimmed evenly from the edges. Before you trust it: This is a center crop, not a freehand crop. If the subject is in a corner, crop in another app first. The file stays in your browser and is not uploaded. The limit is 100 MB. Keep the original until the download has been opened in the program that will use it. A second pass rarely helps. If the first Image file is rejected, read the error from the program that rejected it. Another conversion of a bad result usually makes the file worse, not more compatible. When you are done, you should still have the Image original and one Image download that you have opened. If those two are the same kind of failure, this was the wrong tool and the page above is the place that says so. Photos fail uploads for three separate reasons: the format name, the pixel size, and the kilobyte size. Image Cropper only does the Image to Image step. If the form also prints a pixel size or a 20 KB or 50 KB cap, do that step with the matching tool, starting from the original each time. A second lossy save will not recover detail.
Here is the decision for Image Cropper. You start with Image and you stop when a real program accepts Image. The original pixels are what you have to work with. The edit is local. These tools do not recover detail the camera never captured. Upscale and HD modes enlarge pixels. They are not AI reconstruction. If those two sentences describe a tradeoff you do not want, do not convert. Renaming the extension by hand will not do this job. Running the tool twice on its own output will not do it either.

A related step, if you still need one, is Image Compressor.
Other jobs start from the homepage, where each tool is named for the conversion it actually does.
