As the title implies, I have drawn a rounded rectangle with a larger radius in Photoshop. Now I want to reduce its radius. Is this possible without deleting it?
AFAIK, there is no convenient way of changing corner radius in Photoshop after you've begun drawing a shape. This is one area where Fireworks is pretty nice, as you can simply click on the diamonds at each corner to change the radius.
However, one work around is to use an outer stroke. If the stroke is the same color as the shape, then it will create the illusion of rounded corners. The stroke thickness will be the corner radius, and you can change that at any time.
No, you have to delete it, or trying to work on the mask that is generating to create the radious (but is quicker to delete and restart than not touching the mask).
This is an old question, but it seems like there is still interest in a good answer. Here is the short version: Use smart objects. Make the rectangle as a symbol in Illustrator.
In a bit more detail, here is how you do it:
Now the rectangle is ready to use in photoshop.
Yes you can all you need to do is install

I assume that the shape is already created. Select the shape layer and click the shape using Path selection tool (A). Then go to
How to add or modify round corners to a square or rectangle already created in Photoshop
If you already have your rectangle and want to add some round corners, you can do it this way:
If you need to decrease the radius (corner less rounded), the easiest is to use the guides to trace a new rectangle with the "Rectangle Selection Tool", do the steps below and use these new smaller corner radius as a layer mask on your larger corner radius rectangle... and fill the shape.
If your rectangle had a texture, you might need to use the "Clone Stamp Tool" and fill these new corners. That's where using a layer mask is useful.
If you have many round corner rectangles to adjust, you can simply duplicate the layer mask you just created and apply it to your other rectangles. Layer mask can be resized as well.
Unless you previously used a layer mask on your round corner rectangle, you can't "invent" pixels; you'll need to add them back somehow.
How to create a round corner rectangle or square in Photoshop
To correct a round corner rectangles or squares directly in Adobe Photoshop, you can create a new round corner rectangle, and use it on a layer mask to help you fill the corner to be smaller.
1) Select the "Rectangle Marquee Tool" and trace a rectangle the size you need on a new layer
2) Go in the menu "Select", then "Modify", then "Smooth"
3) Enter the value of the corner radius you want for your rectangle or square.
4) Add this new rectangle to a layer mask on the layer where the original rectangle is, and use the "Clone Stamp Tool" to fill the new corners or simply fill it with a solid color.
How to use a round corner rectangle or square from Adobe Illustrator and import it in Photoshop to modify an existing shape
Another way is to simply create it in Adobe Illustrator, and copy/paste the shape on a layer in Photoshop... and use it as layer mask. You will still need to fill the missing parts of the corner as mentioned above.
1) Press on the "Rectangle Tool" until you see a menu offering you other shapes. Select the "Rounded Rectangle Tool."
2) Click once on your canvas (don't trace the rectangle) and some options will appear.
You can enter your corner radius there and the size of your shape if you want.
If you don't know what size you want, you can still select your corner radius, create that shape and then delete it. THEN trace your rectangle as you want; that's a quick way to set the corner radius of the next rectangles you'll trace!
If you don't really care about a precise measure for the corner radius or simply don't know what value to use, you can simply trace your rectangle or square, and click on the little dot in the corners; drag them to adjust the corner to the shape you want.
You can also import your Photoshop rectangle image if you want to adjust your new round corner visually and prefer Illustrator to do it. The Photoshop image will only serve as a guide.
3) Once you're done, you can simply copy and paste that new round corner rectangle in your Photoshop file, on a layer mask applied to your previous shape. Then you'll need to fill that shape with the "Clone Stamp Tool" or a solid color to fill back these new corners.
