Does anyone know how to compress GIFs without blurring them?

I'm creating some GIFs for a project and I'm having trouble with Among Us compression; the images are blurry, have color noise, and lose detail.

I've tried reducing the color saturation, lowering the FPS, changing tools… but the quality is still not good.

Does anyone have any tips or better GIF optimization tools they can share?

I need to keep the images clear but with a small file size for web use.

Thanks in advance.
