About
Sometimes you need extra space around your GIF without scaling the animation itself. This tool changes the canvas dimensions — add padding on any side, center the animation in a larger frame, or trim excess whitespace from the edges. It is especially useful when preparing GIFs for layouts that expect a specific aspect ratio or fixed container size.
Features
Expand or shrink the canvas independently from the animation itself
Anchor the animation to any corner, edge, or center of the new canvas
Fill extra space with a solid color, gradient, or transparency
All frames are adjusted together so the animation stays perfectly aligned
Guide
Upload the GIF whose canvas you want to adjust
Enter the new canvas width and height in pixels
Choose where to anchor the animation — center, top-left, or any edge
Pick a background color for the added space (or transparent) and download
Pro Tips
Use this to add consistent margins before embedding a GIF in a webpage
Set the canvas to a square aspect ratio for social media profiles that crop to circles
Transparent canvas extension works best when the GIF is going on a colored background
