Frequently Asked Questions

How do I round the corners of an image online?

Drop your image, drag the radius slider to taste (or pick circle crop), and download. It runs in your browser — nothing is uploaded.

Does it keep PNG transparency?

Yes. The rounded or circular corners are exported as a transparent PNG (a WebP stays WebP, which keeps transparency too), so they sit cleanly on any background.

Can I make a circle crop for a profile picture?

Yes — switch to circle mode for a perfectly round crop, ideal for avatars and app icons. On a tall or wide photo, slide the circle so the face stays inside it.

Why is the radius a percentage?

It is a share of the picture's shorter side, so the corners look the same on a phone photo and on a small logo — and every image in a batch gets the same shape. The pixel size for your picture is shown next to it; 50% is fully rounded.

Are my images uploaded?

No. Everything is processed locally in your browser — no upload, no account, no watermark.

Notes from Milo 🐨

The radius slider was in pixels and stopped at 200, which sounds fine until you drop a phone photo: the default 30 px was a hairline on a 4032 × 3024 picture, the slider could never get anywhere near the "fully rounded" it promised, and a batch of a photo plus a small logo came back with two different shapes. The radius is now a share of the picture's shorter side (the pixel size is shown next to it), and 50% really is fully rounded. Circle crop always took the middle of the picture, so on a portrait photo the face at the top was simply cut off; there's now a slider to move the circle. And the download is called photo-rounded.png instead of reusing your original's name.

Drop a whole set now, not one image at a time — the same radius (or circle crop) goes on all of them, and you get them back in a ZIP.
