GIF Cropper
Cut an animated GIF down to the region that matters. Every frame is cropped the same way, so the motion stays intact.
Crop a GIF to a square or circle
Pick “Square” to force a 1:1 box, or “Circle” for a round crop with transparent corners. A circular GIF sits cleanly inside avatar slots and emoji pickers, since the corners are truly transparent rather than white.
Crop a GIF on iPhone or Android
This tool is a web page, not an app: open it in Safari or Chrome on your phone, drop in a GIF from your photo library or files, and drag the box with a finger. Nothing is uploaded, so it also works on a slow connection.
Crop a reaction GIF for Discord or Mudae
Reaction GIFs pulled from the web often carry letterbox bars or a caption strip. Drag the box past the bars, then crop. If the result is still over Discord’s 256 KB emoji limit, run it through the GIF Resizer at 128 × 128 next.
