How to compress a GIF
Adjust compression

NEED TO KNOW
Frequently asked questions
How do I compress a GIF?
Choose a GIF, adjust the resize and maximum color settings, then select Compress GIF. Preview the result and download it if you are happy with the output.
Are my GIF files uploaded?
No. The compression runs in your browser using a Web Worker. Your selected file is processed locally and is not sent to our server.
Will compression reduce image quality?
It can. Reducing dimensions or the color palette may affect sharpness, gradients, and transparency. Try a higher color count or a larger size if the result looks too rough.
Will the compressed GIF keep its animation?
The tool is designed to decode and encode animated frames. Some complex GIFs with unusual transparency or frame disposal behavior may render differently, so always preview the output before using it.
Can I use GIFSmall on mobile?
You can use the page on a modern mobile browser, but large GIFs may require substantial memory and processing time. Desktop browsers are recommended for large files.
Is there a file size limit?
There is no server upload limit because files are processed locally. Practical limits depend on your device memory, browser, GIF dimensions, and frame count.
Does GIFSmall add a watermark?
No watermark is added to the output.
Why is the output file sometimes larger?
Some GIFs are already highly optimized. Re-encoding can occasionally increase file size; compare the before and after sizes and keep the original if it is smaller.
ALSO USEFUL
Need a different size instead?
Resizing changes the dimensions; compressing reduces the file size. If your GIF is the right size but still heavy, stay here. If it's simply too large in pixels, use the GIF resizer to set an exact width and height.
