Capture GIF optimizer and GIF compressor intent with one browser-first tool that focuses on animated output rather than static image compression
Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To compress a GIF, open it in the tool and choose an optimization preset such as balanced, smaller, or aggressive. GIF Optimizer reduces file size by limiting the color palette, capping the frame rate, and applying a lossy level you control, then exports a lighter animated GIF.
You can adjust the controls to find the sweet spot for your use case. Fewer colors and a lower FPS cap shrink the file the most, while a gentler lossy level keeps the animation crisp. The preview lets you weigh size against quality before you download.
All optimization happens locally in your browser. The GIF is never uploaded to a server, so the file stays private on your device while you make it lighter for email, chat, or the web.
Animated GIFs have different tradeoffs from static images. Color count, dithering, and frame-rate limits all shape both file size and playback quality at once, so a dedicated GIF optimizer gives more predictable results than a generic image compressor.
GIF Optimizer focuses on shrinking without changing dimensions. If you also need to change the width and height, that is a separate resizing job. Keeping optimization focused makes it easier to trust the size and quality you end up with.
Short answers for the questions people usually have before trying a utility like this.
Yes. GIF Optimizer is free to use and runs entirely in your browser with no account needed.
No. Optimization runs locally in your browser, so the GIF never leaves your device.
No. This tool focuses on optimization only. Use a GIF resizer when the dimensions need to change.
It depends on the source, but reducing colors, lowering the FPS cap, and increasing the lossy level can cut size significantly while keeping the animation watchable.
Yes. The output remains an animated GIF; only the file size and quality settings change.
