About
A stroke adds a distinct colored edge around the entire outer boundary of your GIF canvas, giving it a bold visual frame. Unlike a border that sits outside the image, a stroke overlays onto the edge of the existing canvas. This is a quick way to make your GIF look more defined, especially when it will sit on a background with a similar color to the animation's edges.
Features
Full color and width control for a stroke that matches your exact design needs

Guide
Upload the GIF you want to add a stroke to
Choose a stroke color and width — thicker strokes are more dramatic, thinner ones are subtle
Preview how the stroke looks on the animation in real time
Download the stroked GIF when you are satisfied with the look
Pro Tips
A contrasting stroke color (like white on a dark GIF) creates the most visual impact
Keep the stroke width proportional to the GIF size — a 2-pixel stroke looks great on small GIFs, but may be invisible on large ones
If you want the stroke outside the canvas rather than overlapping the edges, add space around the GIF first
