GIF resizer
Scale a GIF down for a forum avatar or up-to-spec for a sticker slot. The animation and its loop survive intact.
Scale
Type a width and the height follows, unless you unlock the ratio.

Resizing a GIF is not like resizing a photo
Scaling a JPEG is one operation. Scaling a GIF is two, because every frame shares one palette of at most 256 colours, and the moment you resample the pixels you invent colours that were not in it. Tools that skip the second step — rebuilding the palette afterwards — give you back a GIF with muddy edges and dirty gradients.
This one always rebuilds. That is also why the output sometimes weighs slightly more than a naive resize would: it is a cleaner picture.
Percentage or exact pixels
Percentages are for "make it smaller" — 50% is the safe default and removes three quarters of the pixels. Exact dimensions are for slots with a rule: an avatar box, a sticker spec, a table cell in an email that must not reflow.
Keep the ratio locked unless the target genuinely demands a different shape, and remember that stretching a GIF upward past its original size will not add detail. If you need a bigger version, go back to the source video and convert it again at the width you want.
Questions
Does the animation survive?
Yes — every frame, the timing between them and the infinite loop all come through. Only the dimensions change.
Can I make a GIF larger?
You can, and it will look soft. Upscaling invents pixels rather than recovering them. Converting again from the original video at a higher width always beats upscaling a finished GIF.
Why does the height change on its own?
The aspect ratio is locked by default, so the height follows the width. Switch it to free if you need to squash the picture into a fixed box.
Is there a size limit?
Nothing imposed by us. Very large GIFs are limited by the memory your browser tab can hold.
