How to Format Graphic Designs for Redbubble & TeePublic

Unlike marketplaces where you create separate listings for each item, Redbubble and TeePublic apply a single uploaded image to their entire product catalog.

If your uploaded graphic is too small or lacks transparency, it will show a solid white box on clothing or fail to fit large products like duvet covers.

By formatting your uploads with transparency and high resolutions, you can list designs on 50+ products simultaneously.

Follow these standard export guidelines to secure clean listings:

• Transparency: Save your design with an active alpha channel (transparent background).
• Dimensions: Minimum 5000 x 5000 pixels at 300 DPI to support large merchandise.
• Formats: Export as PNG for apparel and stickers, and JPEG for wall art. Refer to JPEG vs PDF format guide.

Step 1: Isolate the Graphic

Ensure that your graphic has no background layers. If you are uploading a photo, keep the borders clean.

Step 2: Optimize Canvas Space

Trim any excess empty margins around your design to prevent it from showing up tiny on stickers and phone cases.

Step 3: Upscale to Maximum Resolution

Make sure your designs meet the platform limits to ensure prints are sharp.
