Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To resize a GIF, open it in the tool and enter the output width and height. GIF Resizer can lock the aspect ratio so the GIF scales proportionally, and it resizes every frame of the animation before exporting a new animated GIF at your target size.
Choose contain mode to fit the whole GIF inside the target box, optionally with transparent padding or a solid background color, or cover mode to fill the box completely by cropping the overflow. This lets you hit an exact size whether you need the full image or an edge-to-edge fill.
All resizing happens locally in your browser. The GIF is never uploaded to a server, so the file stays private on your device while you scale it up or down for a specific layout, upload limit, or platform.
Resizing and cropping are related but different jobs. Resizing changes the overall dimensions of the GIF, while cropping changes the framing by cutting away part of the image. GIF Resizer focuses on hitting an exact size, which keeps the workflow fast and clear.
If you only want to trim edges or reframe the subject, a crop tool is the better fit. When you need a specific pixel size for an upload, embed, or layout slot, resizing is the right choice and keeps the animation intact.
