Round the corners of an image and save it as a PNG with transparent corners.
The corners outside the curve are cut away and left transparent, so the image sits cleanly on any background colour. JPG can't store transparency, which is why the output is always PNG, even if you upload a JPG. For photos that means a bigger file; resize the image first if that matters.
The radius is measured in pixels of the original image, up to 200, and is capped at half the shorter side. On a 1000-pixel image, 50 to 100 gives a familiar card look. On a large camera photo, even 200 can look subtle, so shrink the photo with the Image Resizer first for rounder-looking corners. On a small square image, the maximum radius rounds it almost into a circle.
On a square image, setting the radius to its maximum makes it close to a circle. For a perfect circle, crop square first and use a circle crop in an editor.
Transparent corners blend with any background. If you need white, place the PNG on a white background in your document or editor.
PNG is needed for transparent corners and stores photos less compactly than JPG.
No. The corners are cut in your browser.
