Redbubble t-shirt mockup generator for your Redbubble artwork

Redbubble accepts JPEG or PNG artwork, capped at 300 MB or 13,500 × 13,500px. Its own guidance is direct on one point sellers often ask about: DPI doesn't affect the final image — pixel dimensions do.

Uploading one piece of artwork on Redbubble automatically applies it across its full product line, so a mockup isn't required for the listing itself. A t-shirt scene here is useful for social posts, a portfolio, or promoting a specific product from your Redbubble catalog outside the marketplace.

Upload up to 50 designs — PNG, JPEG, or WebP, each up to 20 MB — then pick your t-shirt scenes. Mockraft renders every design across every scene you selected in a single batch.

Backgrounds are removed automatically when needed, and the finished batch downloads as one ZIP.

Free renders are unlimited, with a watermark and lower resolution, so you can test a full batch of t-shirt mockups before paying anything.

Pro removes the watermark, renders at full resolution, and runs up to 2 batches in parallel, for $15 / month or $99 / year — no credits to track.
