Answer 1

Modifying hnasarat's answer for windows users. The easiest way to is install InkScape and ImageMagick using Chocolatey and then run the following in a batch file. (It is not as flexible as the other answers you just pass in one svg but it pumps out all the favicons recommended in Favicon Cheat Sheet.

@ECHO off

IF "%1"=="" (
    ECHO You must provide an svg file
    EXIT /b
) 

IF NOT EXIST favicons MD favicons

SET "sizes=16 24 32 48 57 64 72 96 120 128 144 152 195 228 256 512"

FOR %%s IN (%sizes%) DO (
    inkscape -z -e favicons/favicon-%%s.png -w %%s -h %%s %1
)

convert favicons/favicon-16.png favicons/favicon-24.png favicons/favicon-32.png favicons/favicon-48.png favicons/favicon-64.png favicons/favicon.ico

Answer 2

Bash one-liner to convert logo.svg into logo.ico, using Inkscape to export the png images at various sizes:

eval convert \
  '<(inkscape -e /dev/stderr logo.svg -w '{16,24,32,48,64,128,256}' 2>&1 > /dev/null)' \
  logo.ico

Inspired by Malcolm MacLeod's answer, but avoiding the explicit loop and the temporary files.

The stderr and redirection is to avoid Inkscape's success message on stdout (“Bitmap saved as: /dev/stdout”) ending up in the image data.
