Halloween IconsbyFreepik
The pack is free, and it contains 100 high-quality funny and scary Halloween icons.
Inside, you will find things like the aforementioned pumpkins, bats, ghosts; but also graves, skulls, candles, black cats, candy, plus a handful of “all too familiar” characters, like Freddy Krueger or Dracula.
Everything is available in .PNG and .SVG formats, so you can make your own customizations, or just use the simple black-and-white outlined versions.
