How to use it

- Choose quality or target size — Lower colours and scale reduce size.
- Download the optimized GIF — The encoder tries multiple settings automatically.
Features that matter
What GIF Optimizer & Compressor does well.
- Nothing leaves your device — The work happens in your browser tab. There is no upload endpoint in this app, so your files and text cannot be stored, logged or seen by us.
- No upload wait — You skip the round trip to a server entirely. Results are limited by your own CPU, not by network speed or queue size.
- Free, no account, no quotas — No sign-up wall, no watermark, no daily limit. Optional accounts only exist to save favourites and presets across devices.
Frequently asked questions
Is my GIF safe to use here?
Yes. This tool runs entirely in your browser using JavaScript. Nothing you paste or open is sent to a server, and the page keeps no copy after you close it.
Do I need to create an account?
No. Every tool is fully usable without signing in. An account only adds saved favourites and reusable presets.
Does it work on a phone?
Yes. The interface is mobile-first with large touch targets and a stacked layout, so it works on phones and tablets as well as desktops.
How accurate is target size?
It is an approximation based on re-encoding passes. The final file is usually at or below the target, but not byte-exact.
Why do colours look banded?
GIF supports at most 256 colours per frame. Reducing the palette saves space but makes gradients and photos show bands.
