What shapes can I apply?

Rounded rectangle (with adjustable radius) and perfect circle crop. Both preserve animation and apply to every frame.

How do I make a circular GIF?

Select the 'Circle' shape option. The tool crops the GIF to a circle inscribed within its canvas.

Yes. Areas outside the shape become transparent. Make sure your target platform supports GIF transparency (most do).

Use the radius slider. A value of 0 gives sharp corners; higher values create more rounded corners. Use the maximum for a pill shape.

Yes. The same mask is applied to every frame so the shape remains consistent throughout the animation.

You can choose a background color or set it to transparent. Transparent is recommended for overlay use.

Transparent GIFs adapt to any background color in the browser or application. If you set a specific background color, it will show on all platforms.

Re-encoding slightly changes file size. The transparent areas compress efficiently so overall size change is minimal.

The current tool applies the corner mask only. Border drawing may be added in a future update.

No. A new GIF with rounded corners is created in your browser. Your original file is not changed.
