PFP Maker

A PFP maker crops a photo into the square a profile picture has to be, at the pixel size the place you are uploading it to wants. PFP is short for profile picture, and the job is narrower than photo editing: pick the part of the photo that should be in the circle, get it to the right size, and export it without the edges going wrong.

The reason a dedicated crop tool beats a general image editor here is that profile pictures are square files displayed as circles. Almost every site that shows one masks it to a circle at display time, which means roughly 21 per cent of your square is never seen, and all of it is in the corners. Framing by eye in a rectangular editor is how a chin or the top of a head ends up clipped once the circle is applied. This tool shows the circle while you position the photo, so what you see framed is what gets shown.

Dragging moves the photo under a fixed square frame, and zooming scales it. The two are clamped together rather than separately, which is what keeps a blank wedge out of the corner of the export: the zoom has a floor at the point where the photo still covers the whole frame, and how far you can drag depends on the zoom you are at. Drag to an edge and the photo stops there rather than sliding past it, so an export with a transparent or white corner is not reachable.

The size choices run from 128 to 1024 pixels square. Bigger is not automatically better. If the photo's shortest side is smaller than the size you pick, the result is an upscale of that side and looks soft, so the tool says which size the photo fills rather than enlarging it quietly. A 1024 pixel export from a 400 pixel crop is a 400 pixel picture with more pixels in it.

Shape changes what format the file can be. A square crop can be a PNG or a JPG, and JPG is smaller for a photograph. A circle crop has to be a PNG, because the corners outside the circle are transparent and JPEG has no alpha channel, so exporting a circle as JPG would turn those corners black. The format switches on its own when you choose circle, rather than offering a choice that produces a broken file.

The photo is decoded and drawn in your browser and the export is generated locally, so nothing is uploaded. A photo of your own face is about as personal as a file gets, and there is no reason for it to travel to a server to be cropped into a square.
