We HIGHLY recommend uploading .AI or .EPS files. These are the original design files that you can usually obtain from your graphic designer. If you have a vectored .PDF, that will work as well.
Our secondary preferred files are transparent PNG files (meaning, no white background). If you don't have those, we can attempt to work with JPEG and TIFF files. Please send all image files at the highest resolution you have on hand (the bigger the better!)
Note: If you aren't sure which of your files might be best to send, feel free to upload everything you have on hand (seriously) – then we can choose the easiest to work with.
