How To Get Rounded Corners With Shift+Command+3, Shift+Command+4

As you know, “We” are users like you and have no power to implement any suggestions. To have Apple consider your feedback, submit it here:

If you want to screenshot a window and include the rounded corners, you can press Command-Shift-4 then Space and use that to capture an entire window. You will get a transparent-ish border, which I typically remove in Photoshop for a result like this:

For what it's worth, that's not a screenshot with rounded corners. That is an image of a window with rounded corners on a rectangular transparent background.

lol No, it's a screenshot of an object with round corners. The screenshot does not have round corners. Nor can it.

Potato, potaaahto.

Yes, the image file is rectangular. But the periphery of the object is transparent.

Practically, that means I can drop that object onto any background and the area left blank by the rounded corners shows the background.

So practically, a screenshot with rounded corners.

Apple which it seems doesn't give the enduser the option of going back to rectangle corners and is sticking with rounded corners then they should make it system wide and that includes with Shift+Command+3 or Shift+Command+4 since they are still rectangle.

Hopefully you see you can't take a screenshot with rounded corners using command+shift+3 & command+shift+4. Taking a screenshot of a window with rounded corners didn't seem to be the object of your post.

I can’t even see how Apple (or anyone) could do it, technically. Like most image formats, the PNG header/metadata specify an image height and an image width.

That’s a rectangular spec with no fields to specify a rounded corner. The only way it could actually be implemented would be for Apple to apply a radius to the corners and replace the image data outside that radius with the transparent pixel mask. But you’d still have a rectangular image being saved. Technically.

Agreed. That's what I said all along.

Technically, yes. But since the background is transparent it's functionally a screenshot with rounded corners. Compared to something like this, where there are bits of the background visible:

But thanks to the graphical quirks of Tahoe, when you Quick Look that screenshot, macOS also rounds off the corners of the image preview so you no longer see the bits of background.

The updated one is, indeed, a screenshot with rounded corners from a practical perspective. Though I agree with your initial point that I personally do not want my screenshots to have rounded corners.

Rounded corners are a feature of the GUI elements. It doesn't change files.

Personally I sure wouldn't want screenshots with rounded corners.

Then this is a screenshot with rounded corners.

Technically not, because by definition a circle has no corners. 😝

There you go.
