Image Cropper
Crops to a freeform or fixed-ratio region and can auto-trim uniform or transparent borders.
Cropping is the one image operation where the automatic answer is almost always wrong, because the interesting rectangle is a judgement about the picture. So this is a rectangle you place by hand, with the ratio presets and the border trim as the two cases where a machine can decide.
Drag the box to place the crop, or press Trim borders to cut away a uniform or transparent margin automatically. Cropping to PNG keeps the pixels exactly; cropping to JPEG re-encodes them.
Drop an image to crop
PNG, JPEG, WebP or GIF. Read in this tab and never uploaded.
How to use it
Drop one image
PNG goes through a decoder that keeps straight alpha, so a soft shadow is not altered before you have done anything.
Place the rectangle
Drag it, or type exact numbers into the X/Y/width/height boxes. Locking a ratio shrinks the rectangle to fit rather than growing it, so the corner you anchored stays where you put it.
Or trim the border automatically
The corner pixel is the reference: anything matching it within a small tolerance is border. That handles a transparent margin and a white scan with the same rule.
Choose the output format
PNG keeps the pixels exactly — a crop is just a smaller window on the same buffer. JPEG re-encodes, which is a loss the crop itself did not cause.
Common questions
It says there is no border to trim.
The edge pixels are not all the same colour as the corner. A photograph with a vignette or a screenshot with a gradient background has no uniform margin to find; place the rectangle by hand instead.
Can I crop many images the same way?
Not here — a hand-placed crop is about this picture. The resizer’s “cover” mode is the batch answer, and it centres the crop because that is the only defensible automatic choice.
Does cropping remove the EXIF data?
Yes. The output is written from the pixel buffer, so camera, GPS and timestamp tags do not survive. If you wanted them gone that is convenient; if you wanted them kept, crop last.
