What Image Cropper does
Cropping is the only edit on this site that changes what a picture is about rather than how it is stored. Removing the empty half of a photograph makes the subject larger in the frame, and moving the edges changes where the eye goes. It is a compositional decision expressed as a technical operation.
Technically it is the simplest operation there is: the pixels inside your selection are copied out and everything else is discarded. Nothing is resampled or recalculated, so a cropped image is exactly as sharp as the original was in that region. The catch is that you are also discarding pixels permanently, which is why what remains has to be enough for whatever comes next.
When to use it
- Removing dead space
- A photo taken from too far away has a subject occupying a fraction of the frame. Cropping in makes it the picture rather than a detail within one.
- Meeting a required aspect ratio
- Profile pictures want a square, banners want something wide. Locking the ratio means the result fits without the platform cropping it for you at a point you did not choose.
- Removing something at the edge
- A stray hand, a bin, a bystander at the margin of an otherwise good photograph disappears with a crop, and no editing is needed.
- Straightening a composition
- Shifting the frame slightly to put the subject on a third, or to level a horizon after rotating, is a crop rather than a transformation.
Image Cropper settings explained
- Selection
- Dragged directly on the image, with handles on each edge and corner. What is inside is kept and everything outside is discarded — there is no partial or feathered crop.
- Aspect ratio lock
- Constrains the selection to a fixed shape — square, or a specific ratio — so the result fits a destination that requires one. Without it the selection is free in both dimensions.
- Output dimensions
- Shown as you drag, so you can see whether what remains is enough. This matters when the image has a minimum size requirement, because cropping only ever reduces the pixel count.
- Lossless within the crop
- Pixels inside the selection are copied without resampling, so the kept region is exactly as sharp as it was. Only the format's own encoding step, if you save to a lossy format, affects it.
Cropping compared with resizing
| Cropping | Resizing | |
|---|---|---|
| What changes | Which part you keep | How many pixels describe it |
| Composition | Changed | Unchanged |
| Pixel density | Unchanged | Reduced |
| Detail in what remains | Identical | Reduced |
Limits and what to expect
- Cropping only removes — it cannot extend a photo beyond its original edges.
- The result always has fewer pixels than the source, which matters if a minimum size is required.
- Cropping heavily into a small image leaves too little to enlarge again usefully.
- There is no feathering or rounded selection here; the crop is a hard rectangle.
- Images beyond roughly 100 megapixels are refused, because an oversized browser canvas renders blank.
Troubleshooting
- The cropped image is too small for what I need
- Cropping removes pixels, so the result cannot meet a size requirement the crop took it below. Crop less tightly, or start from a higher-resolution original — enlarging afterwards only interpolates and looks soft.
- The image looks soft after cropping
- Cropping itself does not soften anything; the pixels you kept are untouched. What has changed is that you are now viewing a smaller region at the same display size, so any softness already present is more visible.
- I cannot get the exact aspect ratio
- Turn on the ratio lock before dragging. Constraining the selection is far more reliable than trying to match a ratio by eye, and it prevents the destination cropping your image again at a point of its choosing.
- I cropped too much and want it back
- The discarded pixels are gone from the output. Your original file is never modified, though, so open it again and crop differently.
Your files and your privacy
The crop is performed on a canvas inside your browser tab on your own device. Nothing is uploaded at any point, including the full image before you crop it — which is worth noting, since the reason for cropping is often that something at the edge of the frame should not be shared.

FAQ
Does cropping reduce image quality?
No. The pixels inside your selection are copied out without being resampled, so the kept region is exactly as sharp as it was in the original. The only quality change comes from the format you save to, not from the crop itself.
What is the difference between cropping and resizing?
Cropping changes which part of the image you keep, leaving the remaining pixels untouched. Resizing keeps the whole image and changes how many pixels describe it. Cropping alters the composition; resizing alters the resolution.
How do I crop to a square?
Turn on the aspect ratio lock and set it to 1:1 before dragging. The selection is then constrained to a square whatever you do, which is more reliable than matching it by eye — and stops a platform cropping your image again for you.
Can I make an image bigger by cropping?
No — cropping only ever removes. If the subject needs to fill more of the frame you can crop in, but the result has fewer total pixels. Enlarging it afterwards interpolates rather than recovering detail, so it will look softer.
Can I undo a crop?
Not from the downloaded file, but your original is never modified. Open it again and crop differently as many times as you like.
Is my image uploaded?
No. Cropping happens on a canvas in your browser, on your own device, with no request to any server.
