Round GIF Corners
Round the corners of any animated GIF to your chosen radius with transparent or solid fills. Fast, private client-side processing keeps your file on device.
GIF, APNG, WebP, AVIF · static images are accepted too
Tips
- GIF format uses 1-bit binary transparency, which can cause jagged staircase edges along curved cuts.
- Fill the outer corner area with your webpage background color instead of transparency for smooth edges.
- Set the corner radius to half of the image width to generate a perfect circular animated GIF.
How to use it
- 1 Upload your animated GIF from your local drive.
- 2 Adjust the corner radius slider and select transparent or a solid fill color.
- 3 Preview the animation and download the rounded GIF directly to your computer.
What you should know
Standard animated GIFs rely on indexed color palettes capped at 256 colors per frame and support only 1-bit binary transparency. Because partial alpha transparency is impossible in standard GIF files, clipping a rectangular animation into rounded borders often introduces jagged, aliased stair-stepping along curves. Web designers, app developers, and profile badge creators frequently need rounded avatar animations or interface elements without embedding heavy video wrappers. Matching the corner clipping fill to the destination background eliminates visual pixel fringing while keeping playback compatible across all browsers and legacy platforms without CSS masking.
This tool decodes each frame of your animation, clips the layout to your chosen corner radius, and re-encodes the entire sequence entirely inside your browser. You can configure whether the shaved corner regions remain transparent or receive a custom solid background color to ensure smooth blending. Because frames are re-quantized during export, the final file regenerates a synchronized 256-color palette per frame. Existing text metadata, embedded color profiles, and audio tracks are discarded during the re-encoding pass, but timing delays and loop counters are preserved.
Frequently asked questions
Why do the transparent rounded edges look jagged?
GIF only supports 1-bit transparency, meaning a pixel is either 100% visible or 100% transparent without semi-transparent anti-aliasing. To achieve smooth curves, fill the outer corner area with the specific background color of the webpage where you plan to display the GIF.
Does rounding the corners reduce visual quality or frame timing?
Frame durations, dimensions, and loop counts remain intact, but re-encoding rebuilds the 256-color palette for each frame. Subtle dithering may appear on complex gradients, but overall playback timing is unaffected.
Are my files uploaded to a remote server?
No, all frame extraction, corner mask rendering, and GIF re-encoding take place entirely within your browser memory. Your files never leave your computer or phone.
