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.

- 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.

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.
