Change the dimensions of an animated GIF without breaking the animation. Set a width, height or percentage, optionally drop frames or colors to make the file smaller, and see the before and after file size. Everything runs in your browser.

Skipped frames add their delay to the frame before, so the animation keeps its total length.

How to use the Resize GIF
Add your GIF by dropping it into the box, choosing it or pasting it with Ctrl+V. A sample GIF is loaded so you can try it right away.
Set the new size with a scale button, or type a width, height or percentage. The chain button keeps the aspect ratio.
Pick resampling: Smooth for photos and video clips, Pixelated for pixel art and icons.
Reduce the file size further by keeping every 2nd frame or using fewer colors, if needed.
Press Resize GIF, compare the before and after size, and download the new GIF.
How much smaller will my GIF get?
A GIF's file size is roughly proportional to the number of pixels it stores across all frames. This table shows the share of pixels left for common settings (actual savings vary with content):

The new height is calculated from the aspect ratio: new height = new width × original height ÷ original width, rounded to whole pixels. A 480 × 270 GIF resized to 320 px wide becomes 320 × 180.
Common GIF sizes
Chat and messaging reactions: 240 to 320 px wide keeps files small and fast.
Emotes and stickers: 112 × 112 or 128 × 128 px, often with Pixelated resampling.
Email newsletters: 600 px wide or less; keep the file under about 1 MB so it loads quickly.
Websites and docs: match the display width of the column (for example 640 or 800 px).
Smooth vs. pixelated resampling
Smooth scaling averages neighboring pixels with a high-quality filter; strong reductions are done in halving steps, which avoids the jagged, noisy look of a single big step. Pixelated (nearest-neighbor) scaling copies pixels as they are, ideal for pixel art and for enlarging small sprites by whole multiples such as 200% or 300%. To cut away parts of the animation instead of scaling it, use Crop GIF. For still images use the Image Resizer.
Frequently asked questions
How do I resize an animated GIF without losing the animation?
Load the GIF above, choose the new width, height or percentage and press Resize GIF. The tool rebuilds every frame, scales each one and writes a new animated GIF with the same delays and loop setting.
How can I make a GIF file smaller?
The biggest savings come from fewer pixels: 50% scale leaves a quarter of the pixels and usually cuts the file by 60 to 75 percent. Keeping every 2nd frame roughly halves it again, and 64 colors instead of 256 often saves another 10 to 30 percent.
Does skipping frames make the GIF play faster?
No. When a frame is skipped, its delay is added to the frame that is kept, so the animation lasts as long as the original. The motion just becomes a little less smooth.
Which resampling should I choose?
Smooth uses high-quality filtering and suits photos, screen recordings and video clips. Pixelated copies pixels without blending, so pixel art, emotes and icons stay sharp, especially when you enlarge them by 200% or more.
Can I enlarge a GIF?
Yes, up to 4000 pixels per side. Enlarging cannot add detail: smooth scaling makes it slightly soft, and pixelated scaling keeps hard edges. Larger GIFs also produce larger files.
Why is my resized GIF sometimes bigger than the original?
Smooth scaling blends neighboring pixels and creates new in-between colors, which can compress less well than the original flat colors. Try Pixelated resampling, fewer colors, or skipping frames to get a smaller file.
Is my GIF uploaded?
No. The GIF is decoded, resized and encoded by JavaScript in your browser, so it never leaves your device.
