Optimize GIF

Re-encode an animated GIF with selectable frame rate and width using a two-pass palette. File-size savings and visual quality depend on the source and settings. Browser-only, no upload.

Runs entirely in your browser. Your file is never uploaded — no watermark, no account.

Get a better result

Best for
Animated GIFs that exceed chat, email, documentation, or embed limits and can tolerate fewer frames or a smaller canvas.
Input → output
GIF becomes a new looping GIF at 8–15 fps and 320–640 pixels wide with a regenerated two-pass colour palette.
Quality tip
Keep width at or below the source and lower frame rate gradually. Compare text edges and motion after each more aggressive setting.
Know before running
Savings vary, and an already optimized source may not shrink. Fewer frames can make movement less fluid, while palette quantization can alter gradients and subtle colours.
Next step
GIF to MP4 to try H.264 delivery when a video file is acceptable.

    Download. Review the result, then download the finished file from your browser with no watermark.

Frequently asked questions

Is Optimize GIF free? Is there a watermark?
Yes — Optimize GIF is free to use with no sign-up or watermark. Very large files can still be limited by your browser's available memory and processing resources.
Do my files get uploaded to a server?
No. Optimize GIF runs entirely in your browser with WebAssembly, so your GIF file never leaves your device and nothing is stored or seen by us.
What can I put in, and what do I get out?
Optimize GIF accepts GIF and gives you back a GIF file. You can also set frame rate and width before you run it. Actual codec support depends on what the bundled engine or browser decoder can read.
Can I control the output?
Yes — you can adjust frame rate and width, so you decide the balance between file size and quality.
