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
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.
What is the most common mistake when resizing GIF animations?
+
Upscaling. Enlarging cannot invent detail that was never captured, so the result is a soft version of the original at a bigger size. Always resize down from the largest source you have, and resize once rather than in stages.
What dimensions should I actually target?
+
Match the slot it will live in. A full-width web hero rarely needs more than 1920 pixels wide, a content image 1200, a thumbnail 400, and doubling those numbers covers high-DPI screens. Anything beyond that is bytes nobody sees.
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 run Resize 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.
Does Resize GIF cost anything?
+
No. Resize GIF is free, needs no account, and adds no watermark to the output. Uploaded animations are deleted from the workers a short time after the job completes.
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.
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.
Does Resize GIF belong on a site about a photo format?
+
JPEG.to is built around the format that carries nearly every photograph in existence — thirty years old, opened by literally everything, and still the right default for a photographic image. The jobs people bring here are the ones a photograph collects over its life — too big to email, wrong dimensions for a form, wrong way up out of a phone. Resize GIF runs on the same upload and the same account as the conversions because that is where those jobs land.
What is the sensible next step after Resize GIF?
+
The converter on this site moves images to and from JPEG, PNG, WebP and HEIC, which is where the trade between file size and one more generation of loss gets settled. Deciding the format last rather than first is the whole point: every extra save of a photographic image is another generation, and the fewer of them you spend, the more of the picture survives.
Is this the same engine as the other converter sites?
+
Yes — the same libraries, the same workers, the same caps. The difference is which advice is on the page, and here that advice is built on one property of the format the site is named after: the .jpeg and .jpg extensions are the same bitstream, so nothing here behaves differently from a .jpg — only the filename changes.
Is anything kept, and do I need to sign in?
+
Nothing is kept and no account is needed. Uploads are removed from the workers shortly after the job finishes; nothing is looked at, listed or indexed. An account buys history and larger batches, not access.
