How it works
Round avatars are everywhere, but most places that display them crop a square for you — which is no help when you need the round version as an actual file, for a slide, a signature block, a printed card or a site that does not do the cropping itself.
Circle or rounded square
The circle takes the largest circle that fits, centred on the middle of the picture, so a portrait should have the face roughly centred before you start. The rounded square keeps the whole frame and softens the corners by whatever radius you choose.
Why the result is always a PNG
The corners have to be transparent, and JPEG has no transparency at all — saving as JPEG would fill them with white, which defeats the point. PNG keeps them properly clear, so the shape sits correctly on any background.
Check it on a dark background too
Transparent corners look identical to white ones on a white page. If the image will sit on a dark background, view it against one before using it — that is where a badly cut edge shows.
File size
PNG is lossless, so a photographic image saved this way is usually larger than the JPEG you started with. Run it through the image compressor afterwards if size matters, but keep it as a PNG.
Circle crop an image — questions
Why is the result a PNG and not a JPEG?
JPEG cannot store transparency, so the corners would come out white. PNG keeps them genuinely clear.
Does it crop to the centre?
Yes, the circle is centred. Centre the subject first with the crop tool if it sits off to one side.
Is my photo uploaded?
No. The crop happens in your browser.
Why is the file bigger than my original?
PNG is lossless. Compress it afterwards if you need it smaller, but keep the PNG format.
