1Upload the GIF animations that came out the wrong way round.
2Pick a turn of 90, 180 or 270 degrees.
3Apply the rotation; the pixels and the orientation flag are reconciled so every viewer agrees on which way is up.

Rotate GIF FAQ
Can I rotate a whole batch in one go?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
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.
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.
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 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 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.
Can I run Rotate GIF on several GIF animations at once?
+
Yes, and it is worth doing — per-file overhead on an animation is dominated by decoding every frame, so a batch amortises far better than the equivalent set of single runs.
Why does a EPUB site host Rotate GIF?
+
EPUB.to is built around the open eBook format — XHTML in a zip, reflowable by design, and readable on hardware nobody has thought about the layout for. A book is a zip full of markup, images and fonts, so almost every job people bring to an eBook site is really a job on one of those things. Rotate GIF runs on the same upload and the same account as the conversions because that is where it is needed.
What should I do with the result once Rotate GIF is finished?
+
The converter on this site moves books between EPUB, MOBI, AZW3, PDF and DOCX, so a title ends up on whatever hardware is actually going to read it. Doing that after Rotate GIF means the conversion is made from the version you settled on, not from the one you were still fixing.
Is Rotate GIF here the same tool the sibling sites run?
+
The engines are shared — the same toolchain, the same workers, the same limits. What a EPUB site adds is a view on reflow: which of these operations a reflowable book genuinely supports, and which ones only make sense on the fixed-layout media inside it. It also starts from one fact about the format this site is named after: the book is a zip of XHTML with a manifest, so the text costs almost nothing and every decision that matters is about the embedded images and font subsets.
Do I need an account, and does anything get kept?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
