I suppose ffmpeg is the weapon of choice but I didn't find out how to reach my goal.

From here:

ffmpeg -i input.webm -pix_fmt rgb24 output.gif

    @brubaker I think I got you beat: 120K .webm → 2.7G .gif. Yes, that's with a G.

    rgb24 is not supported for gif, ffmpeg would use rgb8 instead automatically. Jan 22 '17 at 8:59

Barafu's answer is alright. But, the resulting gif may have color conversion issue as ffmpeg complains on Incompatible pixel format 'rgb24' for codec 'gif'. Here is what I find works:

First, create PNG Palette:

ffmpeg -y -i input.webm -vf palettegen palette.png

Then, use the palette to produce gif:

ffmpeg -y -i input.webm -i palette.png -filter_complex paletteuse -r 10 output.gif

Extending Raynal's answer, here's a script one can add to .bashrc to do the conversion:

function webm2gif() {
    ffmpeg -y -i $1 -vf palettegen _tmp_palette.png
    ffmpeg -y -i $1 -i _tmp_palette.png -filter_complex paletteuse -r 10  ${1%.webm}.gif
    rm _tmp_palette.png
}

e.g.

webm2gif recording.webm

will create recording.gif.
