A transparent vector SVG file will provide the best results for both engraving and color print.
However, our site will accept any SVG, JPG/JPEG, or PNG file smaller than 10 MB. If you’re uploading a JPG/JPEG or PNG, you’ll want your artwork at least 1000x1000px for drinkware, and 1800x3300px for coolers. Please contact us directly for more specific design specs.
