How to use Resize a GIF Animation
- 1. Upload the GIF. Drop in or browse for the animated GIF you want to resize. Every frame is decoded so it can be resampled to the new dimensions in one pass.
- 2. Enter the new dimensions. Set Width and Height in pixels for the output. Enter both values directly if you want an exact size regardless of the original aspect ratio.
- 3. Download the resized GIF. Download the resulting GIF once resampling completes. Every frame is now redrawn at the new width and height while keeping the original frame delays and loop settings.
When to use Resize a GIF Animation
Resize a GIF Animation changes the pixel dimensions of every frame in an animated GIF at once. It is the direct fix for a GIF that is the wrong size for where it needs to go, whether that means shrinking it or scaling it up. The resampling happens locally in your browser.
- Shrinking a large export for chat apps. A GIF exported at full video resolution is too large for a messaging app that caps dimensions before upload. Resizing it down to 200 by 200 keeps it under the limit.
- Matching a fixed thumbnail size. A CMS template expects animated thumbnails at an exact pixel size. Resizing a source GIF to those dimensions before upload avoids the platform's own resizing distorting it.
- Preparing a GIF for a specific ad slot. An ad platform specifies exact width and height for animated creatives. Resizing the source GIF to that precise size ensures it passes the platform's asset validation.

About the Resize a GIF Animation tool
Resize a GIF Animation does its work locally, right in the browser. Scale every frame of an animated GIF to new pixel dimensions. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the GIF Tools collection on EditSafely, a set of 110 small, focused GIF utilities that share the same instant, private workspace.
You can shape the output with 2 settings, including Width (px) and Height (px), and the result refreshes the moment you change one. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
