NinjaSell supports the most commonly used design file formats for print-on-demand products:
- PNG (recommended)
- SVG
- JPG / JPEG
Among these, PNG files are highly recommended because they support transparent backgrounds, which results in cleaner and more professional-looking prints.
ℹ️ Info: Transparent backgrounds help your designs blend naturally with products like t-shirts and mugs.
💡 Tip: Always export your designs as PNG with transparency for the best results.
