GIF Resizer
Resize animated GIFs while keeping every frame, the timing and the loop. Runs entirely in your browser — nothing is uploaded.
Animation, frame timing and loop are preserved · nothing is uploaded.
How to resize an animated GIF
- 1
Drop or browse an animated GIF.
- 2
Resize by percentage or exact dimensions (aspect ratio locked by default).
- 3
Pick a resampling quality — 'Smooth (fast)' suits GIFs with many frames.
- 4
Click Resize and download — the animation is preserved.
About the GIF Resizer
Animated GIFs are everywhere, but they're often too large or the wrong size. The GIF resizer decodes every frame, scales it while preserving the animation, frame timing and loop, then re-encodes an optimized GIF — useful for fitting a reaction GIF to a chat, a banner, or a forum signature, without uploading the file.
Why resize a GIF?
Animated GIFs are rarely the size you need them to be. A reaction GIF might be too big to fit a chat window, a banner GIF has to match exact ad dimensions, and a forum or email signature often caps how wide an image can be. Resizing solves all of these — but a GIF isn't a single picture, it's a stack of frames, which is exactly why an ordinary image resizer mangles them. This tool is built for the animated case.
What stays intact
Every frame is decoded, scaled, and re-encoded so the animation, the timing between frames, and the loop all survive the resize. The color palette is optimized automatically for the new size, which keeps the result looking clean. For GIFs with a lot of frames, the Smooth (fast) resampling option trades a little sharpness for speed; for short GIFs you can use the higher-quality setting. Because each frame is re-rendered in your browser, a long or large GIF takes a few moments — that processing time is the cost of doing it locally rather than uploading the file.
Making the file smaller too
File size and dimensions go hand in hand with GIFs: reducing the width and height is the most reliable way to bring a heavy GIF down to a manageable size, since fewer pixels per frame means a smaller file overall. If your real goal is a much smaller, shareable animation, it's worth knowing that modern formats are dramatically more efficient than GIF — converting to MP4 or animated WebP with the GIF converter can cut the size by a large margin while keeping the motion smooth.
Frequently asked questions
Does it keep the animation?
Yes — all frames, their timing and the loop are preserved in the resized GIF.
Why does encoding take a moment?
Every frame is re-rendered and re-encoded in your browser, so larger GIFs with many frames take a little longer.
Can I make the GIF smaller in file size?
Resizing to smaller dimensions reduces the file size, and the palette is optimized automatically.
Are my files uploaded to a server?
No. The GIF is decoded and re-encoded entirely in your browser.
Will resizing make my GIF blurry?
Downscaling stays sharp. The higher-quality resampling option is best for short GIFs, while 'Smooth (fast)' suits GIFs with many frames. Enlarging a GIF can soften it.
Is there a limit on GIF size?
There's no fixed limit — it depends on your device's memory. Large GIFs with many frames take longer because every frame is re-rendered in your browser.
