Free browser tool. GIF only. Typical limit 20 MB (10 MB on low-memory devices). Your animation never leaves this device.
Compression runs with Gifsicle in WebAssembly inside your browser. Fogkits does not upload the animation for this tool — no account and no credits required to download. Choosing between GIF tools? Read the Fogkits vs Ezgif comparison.
How to use
No account, no queue, no cloud job. Pick a file, tune the tradeoff, and download when the preview still looks good enough.
01
Drop an animated GIF onto the compressor, or try a sample. The file stays in your browser and is not uploaded to Fogkits for this tool.
02
Start with the quality slider. Optionally set a target size in KB, a max width, or frame skip when chat, email, or an ad platform rejects a large GIF.
03
Compare original and compressed previews, check how much you saved, then download the result. Compression runs locally with Gifsicle in WebAssembly.
Proof
Demo stills from the live Horse sample (Muybridge-style gallop). After a lossy palette and frame-rate pass the file lands around 70% smaller in this static pair. Your savings depend on colors, motion, and the controls you choose — Fogkits does not invent traffic or engagement numbers for this page.
Quality slider
Maps to gifsicle lossy strength and color count.
Target size
Optional KB cap with escalating passes until it fits.
Max width
Downscale to 640, 480 or 320 px while keeping aspect ratio.
Frame skip
Keep every 2nd or 3rd frame when motion can tolerate it.

Demo stills from the Horse sample. Try Fireworks, Celebration, or Pi above to compress another loop in your browser.

Lighten GIF creatives before you upload to ads or a landing page.

Yes. This browser-local GIF compressor is free — no account and no credits. Compress a GIF and download the result when the preview looks right.
No. Fogkits compresses the GIF in your browser with WebAssembly (gifsicle). The original animation is not sent to Fogkits servers for this tool.
Enter a target size in KB. The tool starts from your quality setting, then escalates lossy compression, color count, scale and frame skip until the file fits or the aggressive passes finish.
Start with a higher quality value to keep more detail. Stronger settings shrink the file further but can add dither noise, fewer colors, a smaller canvas, or fewer frames — that tradeoff is intentional.
Frame skip keeps every 2nd or 3rd frame so the animation uses fewer frames and a smaller file. Use it when motion can tolerate a lower frame rate, such as chat stickers or simple loops.
About 20 MB on typical desktops, or 10 MB on devices that report 4 GB of memory or less. GIF only — JPG, PNG and video files are not accepted on this page.
MP4 is usually smaller for video-like clips. Use this page when you specifically need a GIF for chat, email, ads, or platforms that reject other formats.
