How to resize an animated GIF
- Choose a GIF from your device. The tool shows its original dimensions and duration.
- Select Width and enter the target pixel width, or select Percent and enter a scale such as 50.
- Process the GIF, check its dimensions and animation, then download it. Use Continue compressing if you also need fewer KB.
Choose width or percentage
| Setting | What to choose |
|---|---|
| Width | Use a pixel width when a page or design has a known space, such as 400 px. Height is calculated automatically. |
| Percentage | Use 50% to halve both dimensions. Use 100% to keep the original dimensions. |
| Output size | Maximum side: 4,096 px. The 1,000-frame and 50-million-frame-pixel budgets still apply. |
| GIF input | Up to 10 MB on Free or 50 MB on a paid plan. No account is needed for free resizing. |
A single result must be 50 MB or smaller. GIF results sent to the compressor must also fit its input limit: 10 MB on Free or 50 MB on a paid plan.
Example: resize 800 × 600 to 400 × 300
Setting an 800 × 600 GIF to a width of 400 px produces 400 × 300. Choosing 50% gives the same dimensions. Each frame has one quarter as many pixels, but the file size is not guaranteed to fall to one quarter: colors, motion and encoding also affect it.
Resizing, cropping and compression solve different problems
Resize to keep the whole picture at a different scale. Crop to remove part of the picture. Compress when the problem is a byte limit such as 256 KB. Enlarging a GIF does not restore detail that was missing in the source; text and edges can look softer.
The edited GIF is encoded again and can be larger than its source. Check the result size before uploading it elsewhere.
Questions about this tool
Can I resize a GIF without losing the animation?
Yes. This tool resizes every frame and keeps the source frame delays and loop setting. It outputs an animated GIF, rather than exporting only the first frame.
Can I set both width and height?
This version accepts width or a percentage and calculates height to keep the original proportions. For a square result, use Crop GIF and select a square instead of stretching the image.
Will making a GIF smaller reduce its file size?
It often reduces the number of pixels to encode, but it does not set a target in KB or guarantee a smaller file. Download and compare the result, or pass it to the compressor for a separate size reduction step.
Why is my resized GIF rejected?
File size is only one limit. An output can exceed the maximum side, frame count or total frame-pixel budget. Choose a smaller width or percentage. If the source itself has too many frames or frame pixels, export a smaller or shorter version from the original editor first.
