Why compress GIF files?
GIF is one of the oldest image formats still in wide use, and its file sizes can be enormous for what it contains. A moderate-sized GIF can easily reach several megabytes, which is problematic for web pages, email, Slack messages, and social media uploads that enforce size limits.
The format itself uses LZW compression, which is efficient for simple graphics but struggles with photographic or high-resolution content. Reducing the dimensions is often the single most effective way to shrink a GIF. Cutting the width in half typically reduces the file size by 75% or more, since file size scales with the square of the dimensions.
For sharing on messaging apps, embedding in documents, or including in emails, a smaller GIF loads faster and hits fewer size restrictions. This tool extracts the content and outputs a compressed version without requiring any software installation.
This tool outputs a static PNG (the first frame) rather than a re-encoded GIF. PNG offers better lossless compression than GIF for still images.
Compress your GIF in three steps
The compression runs instantly on your device. No files are ever shared or stored.
Upload the GIF
Drag your GIF file onto the tool or click to browse. A preview of the image appears immediately.
Set maximum width
Enter a max width to scale the image down. Reducing from 800px to 400px typically cuts the file size by 70-80%.
Download compressed output

Tips for compressing GIF files effectively
Reduce dimensions aggressively
Cutting the width by half reduces file size by about 75%. For web use, 400-600px is usually plenty of resolution.
Use WebP for web images
If the GIF is going onto a website, convert to WebP instead. WebP offers far better compression than GIF with much higher quality.
Only the first frame is kept
This tool outputs a still PNG from the first frame. Animated GIFs lose their animation in the output.
Check the file size limit
Different platforms have different limits. Slack has a 50 MB limit; Twitter enforces a 5 MB limit for GIFs. Aim to compress until you are well under the limit.
Consider format alternatives
For animation, modern alternatives like WebM or APNG offer much better compression than GIF. For still images, PNG is always superior to GIF.
Frequently asked questions
Will the animation be preserved?
No. This tool extracts the first frame and converts it to a static PNG image. The animation is not preserved in the output.
How much can I reduce the file size?
Results vary, but scaling down a large GIF by reducing dimensions by 50% typically reduces file size by 70-80%. The output PNG also compresses more efficiently than the original GIF format.
What is the output format?
The output is a PNG file, which uses lossless compression and is more efficient than GIF for still images.
Is my file uploaded to a server?
Your images are processed securely and stay private. They are never shared or stored anywhere.
