1Upload the GIF animations you want resized — work from the largest original you have rather than from a copy you already shrank once.
2Type a target width, a target height or a percentage, and leave the aspect-ratio lock on unless you deliberately want stretching.
3Run the resize; every file in the batch is taken to the same target in a single pass.
4Download the resized GIF file, or the whole set together as one archive.
Resize GIF FAQ
Does the source format affect the result of a resize?
+
It does. GIF is capped at a 256-colour palette with single-bit (on/off) transparency and no partial alpha, which is why photographs band and dither in it. That is what decides whether shrinking the file is purely a question of pixels or also a question of re-encoding.
Is there anything specific to GIF I should watch for?
+
Yes — the palette is shared across the whole animation, so any change to one frame is negotiated against the colours every other frame needs. Worth checking before you resize a file you will not be able to regenerate.
How does Resize GIF change the dimensions?
+
Concretely, every frame is resampled to the new dimensions and the palette is re-derived afterwards, because a palette optimised for the original pixel grid is rarely the right one for a smaller grid. You give it a target width, a target height or a percentage, and it works from the original rather than from a previously resized copy.
Can I keep the aspect ratio, or force exact dimensions?
+
Both. Lock the ratio and one dimension is derived from the other, which is what you want almost always. Unlock it and you get exactly the numbers you typed, at the cost of stretching — useful for a fixed slot, wrong for a photograph.
Is animation preserved, or do I get a still?
+
Animation is preserved. Every frame is decoded, processed and re-assembled with the original delays and loop count intact. You only get a still if you explicitly ask for a single frame.
What can I upload to Resize GIF?
+
Animated and static GIFs, plus animated WebP. Still images work too and are treated as a single-frame animation, which is occasionally what you want when building one.
Is there a file size limit on Resize GIF?
+
Yes: free accounts process images up to 5 MB each, which is a real constraint for animation — a few seconds of full-frame GIF reaches that quickly. If an animation is over the limit, cutting the frame rate is almost always a better first move than cutting the dimensions — the eye forgives 12 fps far more readily than it forgives a smaller picture.
Will Resize GIF lower the quality of my GIF animations?
+
The binding constraint on a GIF is not the operation, it is the 256-colour palette. Anything that changes pixel values forces a re-quantisation against a palette shared by every frame, which is where banding and dithering come from. Frame timing and loop count are preserved.
Why would a modern-format site run Resize GIF?
+
WEBP.to is built around the modern replacement for both of the old defaults: one format that does lossy, lossless, alpha and animation, and reliably lands smaller than the JPEG or PNG it came from. People arrive here having decided the old defaults are costing them bandwidth, and that decision immediately raises the rest: what size, what quality, what happens to the transparency. Resize GIF is on the same upload and the same account so those questions get answered in one place.
Once Resize GIF has run, what is worth doing next?
+
The converter on this site moves images to and from WebP, PNG, JPG and AVIF, which is where you decide whether a smaller file is worth losing the older browsers. Doing it in that order matters: pick the pixels first and the container afterwards, because the container is the cheap decision and the pixels are the expensive one.
Do the sibling sites run something different?
+
The engines are identical — same libraries, same workers, same caps. What is different is the opinion attached, and the opinion here rests on a property of the format this site is named after: the same .webp extension can hold a lossy VP8 frame, a lossless one, or an animation, so the sensible processing path is decided per file rather than per extension.
What happens to my file, and is an account required?
+
No account, and nothing is retained: uploads are deleted from the workers shortly after the job finishes, and nothing is inspected, listed or indexed. Accounts exist for history and batch size only.
