Circle Crop Image - Free Online PFP Cropper

What Circle Crop Does

This tool measures your image, takes the shorter of its two sides as the output size, and draws a centered square region onto an in-browser canvas at that size. With Circle selected, it then defines a circular path inscribed in that square and clips to it, so every pixel outside the circle is written as fully transparent rather than filled with a color. With Square selected, the clip is skipped and you get the centered square crop on its own — useful when a platform will apply its own circular mask later. The circle's diameter always equals the shorter edge of your source image, and there is no way to shift the crop off-center. The transparency is the reason the output is always encoded as PNG. JPG has no alpha channel at all, so a circle-cropped image saved as JPG would come back with the corners filled solid black or white and the circular shape effectively gone; the tool does not offer JPG for that reason. The optional border is stroked along the same path used for the clip, inset by half its width so it stays inside the canvas rather than being cut off at the edge. Setting Border Width to 0 disables it entirely. The tool does not resize, upscale, or resample the area it keeps — the pixels inside the circle are the original pixels at their original resolution, and the canvas comes out exactly as wide and tall as your image's shorter side. One side effect worth knowing: if your source was a JPG, the PNG that comes out can be larger than the file you started with, sometimes considerably, because PNG stores photographic detail losslessly instead of discarding it.
