Quick Answer: Optimize
Open Gifur's GIF optimizer, choose a preset or enter a target size, then run the compression search. The tool adjusts colors, scale, frame rate, and duplicate-frame handling; inspect the result because platform limits and encoder output can vary.
Shrink GIFs to hit a target file size — Presets for Discord (8 MB), Twitter (15 MB), and Slack (500 KB), or aim at a custom size — the tool searches for the right quality settings automatically.
Gifur GIF Optimizer is a browser-based compression tool with manual controls, target-size search, and platform-oriented presets.
