We accept all of the standard image formats for both raster and vector art, these include, jpg, png, BMP, and pdf.
You could also be running into trouble because your file is too large, we only accept files up to 10mb. If your file is taking a while to load onto the shirt this could also mean that our site is processing it in the background. This is normal and can take a minute or 2 sometimes, depending on the file type and size, just be patient and it should load 😊
If you are unsure of your file or are still having issues please reach out to us!
