The uploader accepts both JPEG and PNG, but we recommend uploading in PNG format because they allow for transparent backgrounds and their small size makes for quicker uploads. We also recommend choosing a software that supports the CMYK color profile.
These are some of the most popular programs:
- Adobe Photoshop (Paid, CMYK feature built in)
- GIMP (Free, requires CMYK plugin)
- Paint.NET (Paid, requires CMYK plugin)
- Procreate (Paid, only for iOS and iPadOS, CMYK feature built in)
