How can I remove the white pixels around the edges when exporting a transparent GIF?

Transparent smooth edges are impossible in GIF, and Photoshop attempts to reduce these to 1bit by dithering the edges and introducing a matte colour (in your case white, which is the default) as well. This results in the white halos/pixels.

How do I get rid of the white edges on a GIF?

No dithering results in flat, adjacent areas of black, white or a limited number of grays. Pattern dithering places the black-and-white pixels in a grid. Diffusion dithering results in random but evenly spaced pixels and noise dithering pixels are unevenly spaced. The dithering methods give differing shading effects.

What is Alpha dithering?

Dither Transparency If we use dithering as an alpha cutoff threshold, we can set each pixel of an object ‘on’ or ‘off’ (rendered or culled). Even algorithms that render transparent objects in an unsorted order have their own overhead, which screen-door transparency eliminates.
