1Upload the GIF animations that came out the wrong way round.
2Pick a quarter turn or a half turn, or type an arbitrary angle and choose a colour for the corners it will expose.
3Apply the rotation; the pixels and the orientation flag are reconciled so every viewer agrees on which way is up.

Rotate GIF FAQ
Does the format decide whether rotation is lossless?
+
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 property is exactly what determines whether a quarter turn is free or costs a re-encode.
Anything specific to GIF I should know?
+
Yes — the palette is shared across the whole animation, so any change to one frame is negotiated against the colours every other frame needs. It is the kind of thing that explains why a file looks right in one application and wrong in another.
How does Rotate GIF turn the file?
+
Concretely, each frame is rotated by the same amount and the palette is preserved, so timing and loop behaviour survive; the canvas dimensions swap on a quarter turn, which is expected rather than a bug. Quarter turns and half turns are the common case and take the cheapest path available for the format.
Can I rotate by an arbitrary angle, not just 90 degrees?
+
Yes, though the two are different operations underneath. A multiple of 90 degrees rearranges existing data; any other angle has to rebuild the grid and fill the corners, so it costs a resample and usually wants a background colour choosing.
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 Rotate 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 Rotate GIF?
+
Yes: free accounts process images up to 25 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 Rotate 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 Rotate 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. Rotate GIF is on the same upload and the same account so those questions get answered in one place.
Once Rotate 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.
