If you need this icon available in another format, it should be pretty straight forward to download it as an SVG image file, and then import it into apps like Crello, Easil, Illustrator or Pixlr. Converting it to an ICO, JPEG or WebP image format or file type should also be pretty simple (we hope to add that feature to Iconduck soon).
This icon can be used for both Personal & Commercial purposes and projects, but please check the license to see if the designer is requesting attribution (for example, a link back to their website).
