About this tool
Shrinking a GIF is the most effective way to cut its file size: halving the width cuts the pixels per frame by 75%. This tool decodes every frame of the animation, scales it with a high-quality filter, and re-encodes the result with the original timing and looping intact.
Common targets: 320 px wide for chat apps and forum avatars, 480 px for social posts, 128 px or smaller for emoji-style stickers. Enlarging is possible but will look soft, since GIFs are usually low-resolution to begin with.
Everything happens inside your browser. Your file is never uploaded to a server: the conversion runs on your own device using WebAssembly, and the result is downloaded straight from memory. Close the tab and nothing is left behind.
How to use it
- Drop your GIF files into the box above, or click to browse. Nothing is uploaded.
- Adjust the options if you want; the defaults suit most files.
- Click the button and wait a moment.
- Download the results individually or all at once as a ZIP.
Frequently asked questions
How much smaller will the file be?
Roughly proportional to the pixel count: resizing from 640 px to 320 px wide typically cuts the size by 70-75%.
Can I set an exact height?
Height is derived from the width to keep the proportions. Cropping to a different aspect ratio is planned.
Is this really free?
Yes. The site is supported by ads, and there are no limits on how many files you convert.
Are my files uploaded anywhere?
No. The converter runs entirely in your browser. Files stay on your device, which also makes it faster than upload-based converters for anything larger than a few megabytes.
Is there a file size limit?
The only limit is your device's memory. Images and audio of any normal size are fine; for video, files under about 500 MB work well on most laptops and phones.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox, and Safari on desktop and mobile. Very old browsers without WebAssembly support will not work.
