gif corner rounder

world's simplest gif tool

This online utility lets you round the corners of animated GIF files. You can switch between quadratic and circle rounding modes, and round each corner to any radius. By adjusting the radiuses, you can make circular, oval, or parallelogram-like animations. The cropped rounded corners can be filled with any color and the rounded GIF can be easily downloaded from the output preview area. Created by GIF experts from team Browserling.

What is a gif corner rounder?

This is a browser-based program that clips the sharp corners of a GIF and makes them round and smooth. Each corner can be rounded separately by assigning an integer rounding for its radius. In the options, you can find radius fields for the top-left, top-right, bottom-left, and bottom-right corners. The smoothness of rounding is measured in pixels. Bigger radius values crop a larger and smoother arc off the corner but if the radius is set to zero, then the corner remains sharp and isn't rounded. There are two corner rounding techniques that you can choose between: "Quadratic" and "Circle". When using the quadratic rounding mode, the corners are cropped along a path of a quadratic Bézier curve. It's slightly egg-shaped and is actually a parabola. In the circle rounding mode, the corners take the shape of a quarter circle. If the input animation is a square and you set all radiuses equal to half of its width (or height), then the output animation will get cropped to a round circle. You can experiment with the rounding methods and different radiuses as much as you like and you'll instantly see the rounding differences on the screen. In the options, you can also turn the animation mode on or off, as well as view GIF's metadata. To download the rounded GIF, use the buttons below the GIF preview field. Gifabulous!

Round all GIF Corners

In this example, the program cuts off the sharp GIF corners using the quadratic rounding mode. It makes the corners follow a parabolic arc that with a curvature of 40px for each corner. The clipped corners are made transparent by entering "transparent" in the background color option. (Source: Pexels.)

Create a Circular GIF

In this example, we convert a square puppy animation into a circle that's suitable for profile pictures. To do this, we set the radius of all corners to a half of the GIF dimension (its width and height is 320px, so the radius is a half, which is 160px). We use the circle rounding mode and get a perfect circle shape GIF with transparency in the corners. (Source: Pexels.)

Cut Leaf Shape from a GIF

In this example, we create a leaf-shaped autumn forest GIF from a regular rectangular GIF. We use the Bezier curve for rounding the corners and set a different radius for each of the four corners as follows: upper left = 220px, upper right = 5px, lower left = 10px, and lower right = 200px. In the corner fill option, we enter the word "white" that paints the curved corner regions with white color. (Source: Pexels.)
