Imagemagick 7 introduce breaking changes :

  • convert is deprecated in favor of magick (#2366)
  • -coalesce is not implied when formating webp which break compression

webp conversion should be handle like this :

magick "input.webp" -coalesce -filter Lanczos -resize 120x120! -strip -quality 70 -interlace line -sampling-factor 4:2:2 "output.webp"

Command detection should be handled with

if ('command -v magick') {
    shell_exec('magick ....');
} else {
    shell_exec('convert ....');
}
