GIF Resizer
GIF Resizer is a free online tool for resizing animated GIFs. Resize by pixels, by percentage or to a target file size. Everything happens in your browser: no software to install, and your files are never uploaded to a server.

What the GIF Resizer can do
Several ways to resize
Resize by width and height in pixels, by a scale percentage or to a target file size.
Keeps every frame
When you only change the dimensions, every frame and its original delay are kept, so the animation plays at the same speed.
File size presets
Common size presets: 256KB, 512KB, 1MB, 2MB, 5MB and 8MB.
Processed locally
Your files are processed in your browser and never uploaded to a server.
Change the frame rate
Lowering the frame rate (for example 30fps to 15fps) can noticeably reduce the file size.
Batch processing
Import several GIFs at once, resize them all with the same settings, then download them together.
How it works

Real results
See how GIF resizing changes the result
One GIF, any size
The same animated GIF exported at 240, 160 and 96 pixels. Every frame and its timing is kept, and smaller sizes give much smaller files, which helps for avatars, emoji and chat.
- Every frame and its delay are kept, so the motion looks the same.
- Smaller dimensions usually mean a much smaller file.
- Great for avatars, emoji, chat stickers and forum signatures.
Keep the proportions
Lock the aspect ratio and the other side is worked out for you, so the animation never ends up squashed or stretched. Unlock it only when you really need an exact width and height.
- Lock the ratio and type just one side.
- Unlock it only when a platform needs an exact width and height.
- Upscaling past the original size can look soft, so resize down when you can.
Scale by percentage
Halve or quarter a GIF in one step. The tool works out the pixels, so the result stays sharp and in proportion.
- 100%, 50% and 25% of the same flower GIF.
- The file drops from 422 KB to 67 KB at 25%.
- Handy when you don't know the exact pixel size you need.
Frames and timing stay the same
Resizing only changes the pixels in each frame. The number of frames, their order and the speed of the loop do not change.
- 49 frames before, 49 frames after.
- The loop still lasts 2.0 seconds.
- No frames are dropped or merged.

Frequently asked questions
Will my GIF still animate smoothly after resizing?
Yes. The GIF resizer processes every frame and keeps the original frame delays, so the playback speed stays the same.
Why do the colors look slightly different after compressing?
When you compress to a small file size, the tool reduces the number of colors in the palette to save space, which can cause slight banding or noise. Choosing a larger target size reduces this.
What if the GIF can't reach my target size?
If the GIF has many frames or a high resolution, shrink its dimensions first and then compress, or choose a larger target size.
Can I resize several GIFs at once?
Yes. Import several GIFs, resize them all with the same settings, then download them together.
Will lowering the frame rate slow the animation down?
No. When you lower the frame rate, the tool drops frames and lengthens the delay of the remaining ones, so the total duration stays about the same. Motion just looks a little less smooth.
Do I need to pay or sign up?
No. The GIF resizer is free and doesn't require an account.
