A decision guide for choosing pixels, file type, transparency, compression, and product-specific exports before uploading to Redbubble.
When an artist prepares Redbubble sticker artwork, apparel graphics, posters, phone cases, mugs, bags, or puzzles before upload, the right size and format depend on the product. Redbubble accepts JPEG and PNG, product minimums vary, and files above current large-file limits cannot be accepted.
Choose Size By Product Coverage
Redbubble's product dimension list is the safest starting point because a file that fits stickers may not cover wall art, backpacks, tapestries, duffle bags, or jigsaw puzzles. A 9075 x 6201 px master is useful when broad product coverage is the goal, but product-specific exports are still often better for mugs, cases, patterns, and apparel placement.
| Artwork role | Size or export logic | Format logic | Transparency or template risk | Preview checklist |
|---|---|---|---|---|
| Transparent sticker | Use enough pixels for the sticker size you want, up to the current extra-large sticker requirement. | PNG is required when transparency must be preserved. | Rough halos or a background box can appear around the art. | Sticker border, dark/light products, and edge cleanliness. |
| Apparel graphic | Plan around printable area and use larger source art when scaling is needed. | PNG for transparency and crisp type; JPG only for full-background art. | Background boxes, low chest placement, or text near edges. | T-shirt colors, hoodie preview, and print area. |
| Poster or wall art | Use high pixel dimensions and preserve aspect ratio for the selected print products. | JPG often works well for full artwork and photographic texture. | Compression can damage gradients, texture, and fine detail. | Large print options, padding, borders, and crop. |
| Phone case or mug | Create product-specific crops for narrow, curved, or cutout-heavy templates. | JPG for full art; PNG for text or isolated graphics. | Faces, text, or logos can land on cutouts or wraps. | Each device model, mug wrap, and safe area. |
| Pattern or all-over product | Test repeat edges and scale before enabling bags, notebooks, or decor. | PNG for sharp pattern edges; JPG for rich full-bleed artwork. | Seams, huge pattern scale, or visible compression blocks. | Tile repeat, orientation, and all-over preview. |
| Partner Program fan art | Follow the specific brand guideline, tags, and review flow. | Use the format that keeps the approved design clear. | Partner-specific rules are not universal permission. | Brand guideline, review status, and product scope. |
Use PNG And JPG For Different Jobs
PNG is often the safer first choice for transparent stickers, apparel graphics, line art, typography, logos you own, and crisp-edged designs. JPG is often practical for posters, photographic artwork, full-background illustrations, gradients, and texture-heavy images. Avoid saving a transparent design as JPG unless you want a solid background.

PNG is better when a sticker needs transparency. JPG is not appropriate for transparent sticker art because it creates a solid background.
No. That dimension appears for some products and partner contexts, but Redbubble product requirements vary by product and orientation.
